The present invention relates to a postcard and a `~
manufacturing method thereof, more specifically, the present ~:-
~: .
invention relates to a postcard for covering temporarily a
portion provided with a confidential matter formed on a ~ :
surface of a postcard material by adhereing it the portion,
and a manufactu~ing method thereof.
Background Art ~::
As a conventional postcard which constitutes a
background of this invention, there is material including a, ~:~
postcard material formed a confidential matter on a surface
thereof, and a stic~ing material which a pressure sensitive
adhesive layer is formed on the reverse side of postcard
material. ~-
In this conventional postcard, a surface of a postcard `. :~
material can be covered by adhereing it on the surface of the ~.
. ~ . .
postcard material, however, it is not preferably used for :~:
covering temporarily th:e confidentlal matter, since the
sticking material is hardly peeled off from the surface of

the postcard material.
In order to facilitate peeling the sticking material
from the surface of the the material, it is thinking that a
peeling process such as silicon processing is applied on the
surface of the postcard material so as to be peeled off the
sticking material. However, an applying the peeling process
on the postcard material complicates a machinery, and the
cost for manufacturing increases. Therefore, it is hardly to
apply the peeing process. And, further, if peeling process
.::: :.. ::
is applied on the surface of the postcard material, the
sticking material is separated from the postcard material
' '~
inadvertently.

Next, a method of manufacturing the postcard will be
explained.
First, continuous paper for forming the postcard stuff
10 is prepared. The postcard material 12 portion and the
base materlal 18 portion are formed continuously in the
direction of width of this continuous paper. Accordingly,
the length of the continuous paper in the direction of width
is a sum of the length of the postcard material 12 and the
lenyth of the base material 18. And the suppression layer 20
is formed on one main surface of the base material 18 of the
continuous paper by allover printing with a silver ink, for
: 1,: . I ;
example, by the known printing method as the offset printing
or coating.
As showing Fig. 3, a rolled laminate comprising the
: . :
postcard stuff 10 formed with the suppression layer 20 -~
12
:~ '
~ .
~" 2~2~
is mounted on a hold roller 32 of a manufacturing machine 30
for the covering material.
The postcard stuff 10 held by the hold rc>ller 32 is
loosen at one end and led to a resin coater 34. The resin
coater 34 is designed to print and coat the resin 22a such
as the aforesaid vinyl chloride-vinyl acetate copolymer on
- ,:
the suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is
printed and coated is then guided to a dryer 36, whereby the
resin 22a is dried and the primer layer 22 is formed.
Next, the base material 18 -formed with the primer layer
22 is directed to a heat adherent resin coa~er 40 for
printing and coating the heat adherent resin 24a containing,
for example, the aforesaid ethylene-vinyl acetate
copolymerized resin as a main component. The heat adherent
resin coater 40 is a printing or coating machine utilizing
known printing and coating methods such as a typographic
printing, gravure printing, silk screen printing, o-ffset
printing or the like.
By- the heat adherent resln coater 40, the heat adherent
resin 24a is printincJ or coating on the surface of the primer
layer 22.
The base material 18 onto which the heat adherent resin
~ .
~ 24a lS printed or coated is led to a dryer 42, whereby the
~ -:
heat adherent resin 24a is dried and the first heat adherent
13
"` :'. :'
2 ~
resin layer 24 is formed. -
Thus, as shown in Fig. 4, the covering material 14 of
the postcard stuff lO is formed with the suppression layer
20, the primer layer 22 and the heat adherent resin layer 24
on the surface of the base material 18.
The continuous postcard stuff lO is wound round a take-
up roller 44 ayain.
In this embodiment, as shown in Fig. 2A and Fig. 4, the
suppression layer 20 is formed on one main surface of the
base material 18, the primer layer 22 is formed on the
surface of the suppression layer 20, and the heat adherent
resin layer 24 is formed on the surface of the primer layer
22. The adhesion of the heat adherent resin layer 24 is
increased by the primer layer 22. Therefore, the heat
adherent resin layer 24 is adhered strongly to the base
~::
material 18, and adhered weakly to the postcard material 12.
-~ Wl en the aluminum foil and the like having a ~ood
suppressiveness is selected as the base material 18, the
suppression layer 20 is not necessary. In this case, the
primer layer 22 is formed on one main surface of the base
material l8.
Further, as a material of the postcard stuff lO, a ~ -
rolled coI1tinuous paper is selected, but a loose paper, that
; is to say, a separated paper may be selected.
~ ~ ~ Also, on the base material 18, any suitable printiny
;~ 14
-
: ' :
--~ 2~2~
which fits to properties of the postcard may be perforrned, or
when the continuous material is used as aforesaid
embodil~ents, for example, a detecting mark(arrow) for
detecting feeding pitches of the base material 18 may be
printed with a black color or the like.
Subse~uently, this postcard stuff 10 is led to a
covering material sticking apparatus stic]cing this covering
raaterial 14 to the postcard material 12. At this time, to
cover a confidential matter such as a residual amount
deposited in a bank which is formed on part of the surface of
the postcard with the covering material 14, it is necessary
to print proper characters in advance on a proper place, for
example, the lower column of the postcard material.
:~ :
~ In addition, in the case of making this covering ~
. ~ ,.
material 14 adhere, for example, to the lower column of the ;~
postcard, as shown in Fig. 5, the postcard stuff 10 is fed
sequentially, and it is folded back at the boundary between ~;
the postcard material 12 portion and the covering material 14
portion, and the covering material 14 and the postcard ~ ;~
material 12 are bonded. Then, the surface of postcard stuff
10 is pressed by a pressing roller, and the covering material
14 is stuck to the surface of the postcard material 12. ~ `
Then, the postcard stuff 10 i9 cut in a proper size, and the
postcard of the present invention is formed.
In the adhered covering material 14, the adherent resin
;~
: ' ~
','.,.'f', ," '
--` 2~2~
layer 24 is adhered strongly to the kase material 1~, and
suppression layer 20 is adh~red wea]~ly to the postcard
material 12. Thus, as shown in Fig. lA and Fi~ , the
covering material 14 can be peeled off relatively easily from
the postcard material 12 by cutting it.
Also, the covering material 14 can be peeled off
relatively easily by not cuttins.
And, the lottery part 16a and the confidential matter
16b formed on a ~urface of the postcard material 12 can be
seeing.
Fig. 6A and Fig. 6B are views showing an another
embodiment Gf the present invention, in which Fig. 6A is a
perspective vieu therof, and Fig. 6B is a sectional view
thereof.
In this embodiment, cuts 26a and 26b forming with
~;~ parforations are forn~ed specifically in the upside and the
downside of the base material 18, the suppression layer 20,
the prlmer layer 22 and the heat adherent resin layer 24. The
cuts 26a and 26b are formed by a perforator including a
cutter roll so-called die roll or by a perforator including~
a die cutter having a cutter blade.
In this embodiment, when the center portion of the
covering material 14 in the up-and-down direction is peeled
off, as shown in Fig. 7A and Fig. 7B, the center portion can
be ~eeled off relatively easily from the postcard material 12

by cutting the covering material 14 at the cuts 26a and 26b.Then, the lottery part 16a and the confident1al matter 16b on
the surface of the postcard rnaterial 12 can be seeing.
Fig. 8A and Fi~y. 8B are perspective views showiny a ;
separate embodiment of the present invention, in which Fig.
8A is a perspective view thereof, and Fig. 8B is a sectional
view thereof. In this embodiment, a separate cut 26c is
formed specifically in the base material 18, the suppression ;;~
layer 20, the primer layer 22 and the heat adherent resin
layer 24 on the inside of the cut 26b. The cut 26c is formed
by a die roll together with the cuts 26a and 26b.
Furtherrnore, a half circle cut portion 26d is formed at one
end of the base material 18, the suppression layer 20, the
primer layer 22 and the heat adherent resin layer 24 in
between the cuts 26b and 26c.
In this embodiment, when the center portion of the
covering material 14 in the up-and-down direction is peeled
off, as shown in Fig. 9A and Fig. 9B, a narrow portion
between the cuts 26b and 26c is peeled off, first. In this
case, the narrow portion between the cuts 26b and 26c can be
peeled off easily by hooking a finger to the cut portion 26dn
Then, the lottery part 16a and the confidential matter 16b
can be seen by bending the center portion of the covering `~
material 14 in the up-and-down direction at the cut 26a or by
cutting it at the cut 26a. `~

Meanwhile, in the embodiment shown in Fig. 8A and Fig.
8B a projection extending to the outside in between the cuts
26b and 26c may be formed in place of the cut portion 26d.
Thus, the narrow portion of the covering material 14 is
peeled off more easily by hooking the projection.
Also, a center portion of the covering material 14 may
be formed so as to peel off from the postcard material 12 by
forming a cut alony the surrounding of the base material 18,
the suppression layer 20, the primer layer 22 and the heat
adherent resin layer 24,
Also, the lottery part 16a and the confidential matter
16b may be formed on the surface of the suppression layer 20
or the surface of the postcard material 12 when having the
the suppression layer 20, and may be formed on one main
surface of the base material 18 or the surface of the
postcard material 12 when not having the suppression layer
20.
Fig-. 10 is a sectional view showing a postcard as a

material 14 is formed integral with the postcard material 12
in a manner of extending froln one end thereof and is stuck to
the postcard material 12 in a folded-back fashion.
A lottery part 16a wherein are shown letters such as
"winniny" or "blank" and a confidential matter 16b such as a
inforrnation of the finance or the insurance are formed on the
surface of the postcard material 12.
The covering material 14 comprises a base material 18
for~ed integral with the postcard material 12 in a manner of
extending from one end thereof.
The base material 18 is formed with a relatively soft
material such as paper, synthetic resin film and the like
which can be cut by a scissors or the like. And on one main
surface of the base material 18 a suppression layer 20 is
formed.
: , , .
On the surface of the suppression layer 20, a primer
layer 27 for increasing an adhesion of a heat adherent resin
layer 28 discribed layer is formed. The 2rimer layer 27 is ~;
formed by coating a resin such as vinyl chloride-vinyl
acetate copolymer on the surface of the suppression layer 20. - -~
.
On the surface of the primer layer 27, the first heat ;
adherent resin layer 28 is formed by coating a heat adherent
resin with a weak adhesive strength as heating and extruding
~;it, or by gravure or silk screen printing as dissolving it in

a solvent or despersing in water and the firsts heat adherent
resin layer 28 has a weak adhesive strength.
The first heat adherent resin layer 28 is forrned to melt
at about 100C to 200C so as to be adhered to the postcard
material 12 made of paper or the like with a weak adhesive
strength.
As an example of said heat adherent resin having a weak
adhesive strength, the same adhesives as adhesives of the
aforementioned embodiment shown in Fig. 1 may be selected~
Further, on the surface of the first heat adherent resin
layer 28, a second heat adherent resin layer 29 having a
strong adhesive strength is forr.ledO In this embodiment, the
second heat adherent resin layer 29 is formed at both sides
in the lengthwise direction of the postcard material 12, that
is, in the fixed width at the upside and downside of the
.
covering material 14. ~oreover, tne second heat adherent
resin layer 29 is formed at both sides in the breadthwise
direction of the postcard material 12, that is, at right and
left ends of the covering material 14 in spots. The second
heat adherent resin layer 29 is formed by coating a heat
adherent resin having a strong adhesive strength, for example
adhesives of EVA group, stylene-butadiene-stylene copolymer,
stylene-isoprele-stylene copolymer iIl parts.
In this case, for example, the tackifier is mixed more
as compared with the heat adherent resin having a weak
~,

-~ 2~%~
.
adhesive strength or the release agent is mixed less as
compared with the heat adherent resin having a weak adhesive
strength, in the heat adherent resin having a stron~ adhesive
strentgth. The second heat adherent resin layer 29 may be
formed at only both sides of upside and downside or both
right side and left sides of the coveriny material 14.
In this case, the second heat adherent resin layer 28
may be formed in a fixed width or spots.
Next, a method of manufacturing the postcard shown in
Fig. 10 will be explaned.
First, continuous paper for forming the postcard stuff
10 is prepared. The postcard material 12 portion and the
base material 18 portion are formed continuously in the
direction of width of this continuous paper. Accordingly,
the length of the continuous paper in the direction of width
is a sum of the length of the postcard material 12 and the
length of the base material 1~
As showing Fig. 12, a rolled laminate comprising the
postcard stuff 10 formed with the suppression layer 20
is mounted on a hold roller 132 of a manufacturing machine
130 for the covering material.
The postcard stuff 10 held by the hold roller 132, is
loosen at one end and led to a resin coater 134. The resin
coater 134 is designed to print or coat the resin 27a such as
the aforesaid vinyl chloride-vinyl acetate copolymer on the
~..;.....

suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is
printed or coated is then guided to a dryer 136, whereby the
resin 22a is dried and the primer layer 27 is formed.
NeY.t, the postcard stuff 10 forrned with the primer layer
27 is directed to a heat adherent resin coater 140 for
printing or coating the heat adherent resin 28a with a weak
adhesion containing, for example, the aforesaid ethylene-
vinyl acetate copolymerized resin as a main component. The
heat adherent resin coater, 140 is a printing or coating
machine utilizins known printing and coating methods such as
a typographic printins, gravure printing, silk screen
printing, offset printing or the like.
By the heat adherent resin coater 140, the heat adherent
resin 28a having a weak adhesive power is printing or coating
on the surface of the primer layer 27.
The postcard stuff 10 onto which the heat adherent resin
28a is printed or coated is led to a dryer 142, whereby the
heat adherent resin 28a is dried and the first heat adherent
resin layer 28 is formed.
Then, the postcard stuff 10 formed with the first heat
adherent resin layer 28 or the like led to a heat adherent
resin coater 144 for printing or coating- the heat adherent
~ resin 29a having the strong adhesion. The heat adherent resin
.~; .
coater 144 is a printing or coating machine utilizing known
: `

-`' 2~2~'Z~, ~
printing and coating methods such as a typoZ~raphic printing,
gravure printin4, silk screen printing, offset printing or
the like. By the heat adherent resin coater 144, the heat
adherent resin 29a having the strong adhesion is printed or
coated partially on the surface of the first heat adherent
resin layer 28.
The postcard stuff 10 onto which the heat adherent resin
29a is printed or coated is led to a dryer 146, whereby the
. .
adherent resin 29a is dried and the second heat adherent ~ `
resin layer 29 is formed. ~ ~ ,
Thus, as shown in Fig. 10, the postcard stuff 10 is ;
formed with the base material 18 on which the suppression `~

layer 20, the primer layer 27, the first heat adherent resin ;---
layer 28 and the second heat adherent resin layer 29 is
formed in order.

The postcard stuff 10 is wound round the take-up roller
148 again.
In this embodiment, as shown in Fig. 10, the suppression
layer 20 is formed on one main surface of the base material -~

28 is formed on the surface of the primer layer 27. The ;~
adhesion of the first heat adherent resin layer 28 is
increased by the primer layer 27. Therefore, the first heat -
adherent resin layer 28 is adhered strongly to the base

material 18.
In this embodirnent, the second heat adherent resin layer
29 is formed on a surface of tlle first heat adherent resin
layer 28 in the fixed width at the upside and downside of the
covering material 14. Moreover, the second heat adherent
resin layer 29 is formed on a surface of the first heat
adherent resin layer 28 at right and left ends of the
covering material 14 in spots.
Therefore, at a portion which the second heat adherent
resin layer 29 is formed, the covering material 14 is adhered
to a postcard material 12 strongly, and at a portion which
the second heat acherent resin layer 29 is not formed, the
covering material 14 is adhered to it weakly.
; Thus, as shown in Fig. ll, at the portion where the
second heat adherent resin layer 29 is not formed, the base
material 18, the suppression layer 20, the primer layer 27
and the first heat adherent resin layer 23 can be relatively
easily cut and peeled off from the postcard material 12. In
this case, at a portion which the second heat adherent resin
layer 29 is formed in spots the base rnaterial 18, the
suppression layer 20, the primer layer 27 an~ the first heat

embodiment of the instant invention. In this embodiment,
cuts 26a and 26b forming with parforations are formed
specifically alony the surroundiny of the second heat
adherent resin layer 28 in the upside and the downside of the
base material 18, the suppression layer 20, the primer layer
22 and the first heat adherent resin layer 28.
In this embodirnent, as shown in Fig. 14, the base
rnaterial 18, the suppression layer 20, the prirner layer 27
and the first heat adherent resin layer 28 can be peeled off
relatively easily from the postcard material 12 by cutting at ~
the cuts 26a and 26b, in a portion where the second heat ~- -
adherent resin layer 28 is not formed. Then, the lottery
part 16a and the confidential matter 16b on the surface of
the postcard material 12 can be seeing.
In the aforementioned embodiment, the cut is formed
along the surrounding of the coveriny material, a center
portion of the covering material can be cut by the cut.
In this case, as shown in Fig. 15, when each cuts are
constituted with a linear cut portion 224a and a curvilinear
cut portion 224b respectively so as to overlap a part of one
cut 224 and a part of the next cut 224 in a direction for
peelingoff the covering mateial 212, the center portion of
the covering material 212 can be peeled off easily. In ~
addition, for peeling off the center portion of the coveriny ;~ -
material 312 easily, as shown in Fig. 16, for example, each

linear cuts 324 may be formed along edyes of the base
naterial 314 on a slant so as to overlap a part of one cut
324 and a part of the next cut 324 in a direction for peeling
oI'f the coverins~ material 312.
In the postcard shown in Fic;. 15 and Fiy. 16, by
pulling the covering material between the adjacent
perforations is broken as the direction thereof is shown by
an arrow of dash-dot line, and the covering rnaterial of the
portion encompassed by the perforation is peeled off.
However, as shown in Figs. 15 and 16, the same covering
material as the postcard material rnay be formed and the
covering material may be forrned so as to be stuck to cover

When peeled off the base material, the base material,
the primer layer and the heat adherent resin layer are peeled
off from the postcard material in the postcard including the
base material having the suppressiveness, while, the base
rnaterial, the suppression layer, the primer layer and the
heat adherent resin layer are peeled off from the postcard
material in the postcard including the suppression layer
having the supprssiveness. Therefore, the surface of the
postcard material can be seeing.
The first heat adherent resin layer is adhered weakly to
a postcard material and the second heat adherent resin layer
is adhered strongly to the postcard material.
Also, the adhesion of the first heat adherent resin
layer is increased by the primer layer. Therefore, the first
heat adherent resin layer is adhered stronyly to the base

material or the suppression layer. Therefore, the basematerial is not accidentally peeled off from the material to
be stic]ced with a force applied to the second heat adherent ;
resin layer. Then, the surface of the postcard material is
covered with the base material of the postcard material
including the base material having the suppressiveness or
