DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel seal supply sheet in which one or a plurality of blind seals are releasably attached to a backing paper. In particular, the present invention relates to a seal supply sheet for supplying a blind seal provided with a blind layer that an individual can hide below written in a personal communication or the like, and can be easily removed by a recipient by rubbing with a nail or a coin.

[0002]

2. Description of the Related Art Scratch sheets and the like which are conventionally used for simple lotteries and the like are provided as a cover having a blindfold layer which can hide a material written below and can be easily removed by rubbing or the like. Can be.

[0003] This scratch sheet has a structure in which a blind layer is formed on a part of the surface of a printed material to hide what is written underneath. The blind layer may be rubbed with nails or coins, or the blind layer may be hidden. It can be easily removed by sticking an adhesive tape on and peeling it off.

[0004]

However, the conventional scratch sheet is formed by printing a blindfold layer on a printed material which has been printed in advance, and is used for personal enjoyment such as blindfolding in private communication. I couldn't do that.

[0005] In view of the above, an object of the present invention is to provide a blind seal supply sheet that can be used personally, such as a blindfold in a private communication.

[0006]

The present invention solves the above-mentioned problems by the following constitutions.

[0007] A seal supply sheet comprising one or a plurality of blind seals releasably attached on a backing sheet,
A re-adhesion layer (pressure-sensitive adhesive layer) and a transparent seal carrier layer are sequentially laminated on the surface of the mount via a release layer if necessary, and a blindfold layer is formed entirely or partially on the seal carrier layer. The blindfold layer is formed by printing with an ink containing an inorganic powder concealing agent and a silicone release agent as essential components, and can be easily removed by rubbing (scratch) or the like. In addition, a notch is formed up to the re-adhesive layer, and if necessary, the cutout is removed leaving a blind seal portion.

[0008] The blindfold seal supply sheet has a structure in which the blindfold layer has a hydrophilic surface on which an electrophotographic toner or a heat-sensitive or ink-jet ink can be placed, so that the blindfold layer can be individually placed on the blindfold layer. Any information such as pictures and characters can be added to the screen, and the way of enjoying using the blindfold seal is diversified.

[0009] Further, by making the above-mentioned blinding layer a multilayer structure of a hiding layer and a printing surface layer, it becomes easy to select a material composition more suitable for hiding and printing, respectively.

In the above, the printing surface layer is formed of a coating film of a paint containing a white pigment or a light-colored pigment and a hydrophilic resin, so that the blindfold layer is formed of an electrophotographic toner or a heat-sensitive ink jet. It is easy to provide a hydrophilic surface on which the ink for the system can be placed.

[0011] The blind seal supply sheet of each of the above constitutions is
By further printing information such as pictures and characters on the surface of the blindfold layer, the commercial value of the supply sheet can be increased.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

(1) Basically, as shown in FIGS. 1 and 6, one or a plurality of (in the illustrated example, a plurality of) blindfold seals 11,
11A are the seal supply sheets 12 and 12A which are releasably attached to the mount 13.

The blind seals 11, 11A are shown in FIGS.
As shown in FIG. 1, a release layer 15, a re-adhesive layer (adhesive layer) 17, and a transparent seal carrier layer (hereinafter simply referred to as "carrier layer") 19 are sequentially laminated on the surface of the mount 13, and on the carrier layer 19, The blindfold layer 20 is formed entirely or partially (in the illustrated example, partially). Then, a notch 18 is formed up to the re-adhesive layer 17 on the outer peripheral side or the inner peripheral side according to the shape of the blindfold seals 11 and 11A,
If necessary, the extra re-adhesive layer / transparent carrier layer is removed.

The mount 13 is not particularly limited as long as it can be used for a mount such as a seal, and pulp paper, synthetic paper, plastic sheet, transparent film or the like can be used as a base material. When a non-polar polymer such as PE or PP is used as the backing material and has releasability itself, a release layer described later is not required. Its thickness is usually
The thickness is 8 to 450 μm (preferably 10 to 400 μm, more preferably 20 to 350 μm). If it is too thin, it is difficult to obtain the necessary strength when peeling off (removing) the seal from the backing sheet, and the workability of removal is not good. If it is too thick, it becomes bulky during storage and wastes material.

The release layer 15 remains on the backing sheet 13 until the seal is applied.
And the film layer 19 are temporarily bonded, and there is no particular limitation as long as both the mount 13 and the re-adhesive layer 17 have adhesiveness. The thickness of the release layer 15 is usually 0.5 to
50 μm (preferably 1 to 40 μm, more preferably 1 μm
３０30 μm). Instead of applying a release agent on the surface of the mount 13 and laminating the release layer 15, a commercially available release paper having both the mount 13 and the release layer 15 may be used.

The re-adhesive layer 17 has a general-purpose adhesive (for example, acrylic or silicone) used for the re-adhesive layer such as a seal, which has adhesiveness to both the film layer 19 and the paper to which the seal is applied. ) Can be used. The thickness of the re-adhesive layer 17 is usually 2 to 70 μm (preferably 5 to 6 μm).
0 μm, more preferably 5 to 50 μm).

As the transparent carrier layer 19, a layer made of polypropylene (PP), polyethylene (PE), polyester, or the like can be used.
It is desirable to use PP. The thickness of the carrier layer 19 is generally 16 to 150 μm (preferably 20 to 1 μm).
00 μm, more preferably 40 to 70 μm). If the carrier layer 19 is too thin, peeling (removal) of the blind seal 11 and handling after removal are not good. If the carrier layer is too thick, as in the case of the backing paper, it becomes bulky during storage and wastes material.

As the carrier layer 19, a commercially available transparent adhesive film having the re-adhesive layer 17 can be used instead of laminating the re-adhesive layer 17 on the back surface.

The cover layer 20 is formed by printing an ink containing an inorganic powder cover agent and a silicone release agent as essential components on the surface of the film layer. The thickness of the blindfold layer 20 is usually 2 to 100 μm (preferably 5 to 80 μm, more preferably 5 to 50 μm) in a case where the blindfold layer 20 is rubbed off with a scratch. If it is too thin, it is difficult to secure the concealing property, and if it is too thick, the same material as described above is wasted, and furthermore, it is troublesome to remove the blindfold layer by scratching. When the edges are to be peeled off together, the thickness is usually 50 μm, preferably 100 μm or more, and the upper limit is from the viewpoint of material saving.
It is 200 μm or less.

The ink forming the blindfold layer 20 contains an inorganic powder concealing agent and a silicone release agent as essential components. In addition to the above components, a synthetic resin such as an acrylic resin or a polyester resin and the above components are dissolved. Containing an organic solvent or the like. As the inorganic powder concealing agent, metal powders such as aluminum powder, inorganic pigments such as titanium oxide and carbon black and the like can be used, and among these, aluminum powder has a high concealing property and can be suitably used. The content of the inorganic powder hiding agent in the ink is usually
It should be 10 to 50% by weight (preferably 20 to 40% by weight).

The content of the silicone release agent in the ink is usually 0.1 to 10% by weight (preferably 0.2 to 8% by weight).
wt%, more preferably 0.5 to 5 wt%). If the content is too low, the carrier layer 19 of the blind layer 20
On the contrary, if it is excessive, it is difficult to secure temporary adhesiveness until the carrier layer 19 is peeled off.

Screen printing, gravure printing, sticker printing, and the like are possible as the printing method of the cover layer 20 on the carrier layer 19, and screen printing is preferable because a thick ink film can be printed.

It is also possible to make the ink contain a dye such as a sublimable dye or an organic dye (organic pigment).
When the sublimation dye is contained, the carrier layer 19 can be colored simultaneously with the blindfold layer 20 when the blindfold layer 20 is printed. At this time, as a material for forming the carrier layer, PP is preferable because of relatively good dyeability.

When an organic pigment is contained, only the blindfold layer 20 can be colored. Furthermore, it is also possible to use a previously colored film as the carrier layer 19, in which case the carrier layer 1
It is possible to manufacture a material in which only 9 is colored, or a material in which the carrier layer 19 and the blind layer 20 are colored in different colors. As the sublimable dye and the organic pigment, general-purpose dyes can be used.

In the case where the carrier layer 19 is colored, the blind seal 11 is removed even after the blind layer 20 is removed.
It is easy to check the location where the label is attached. In addition, the blindfold layer 20
Is colored to a chromatic color other than gray (silver),
An increase in the decorative effect can be expected by attaching a seal.

FIG. 4 shows another embodiment of the present invention.
As shown in 6.8, information 23 such as pictures and characters is printed on the surface of the blindfold layer 20, and the blindfold seal supply sheet 2 is printed.
It is also possible to increase the commercial value of 2, 12B.

Examples of a method for printing the information 23 include gravure printing, screen printing, offset printing, resin letterpress printing, and the like. Since the blindfold layer 20 does not easily peel off, printing by resin letterpress printing is preferable.

When printing is performed personally, at least the surface side of the blindfold layer 20 has a hydrophilic property on which hydrophilic ink or toner can be placed so that color copying, laser printer, ink jet, etc. can be easily applied. Configuration.

The hydrophilic aspect is not particularly limited. For example, (1) the blinding layer 20 may be a printing layer of an ink containing a hydrophilic resin and a concealing agent, or (2) the blinding layer 20 may be The multilayer structure of the concealing layer 20a and the printing surface layer 20b (see FIG. 9), and the printing surface layer 20b is formed of a coating film of a paint containing a light-colored pigment and a hydrophilic resin. Here, it is usually desirable to use a white pigment as the light-colored pigment for clear printing.

As the hydrophilic polymer, polyurethane resins, acrylic resins, etc., and further, low-substituted starch derivatives, dextrins and cellulose derivatives can be suitably used.

Further, as still another embodiment of the present invention,
As shown in FIG. 5, a blind seal supply sheet 32 in which a protective layer 25 is laminated so as to cover at least the entire blind layer 20 from the front side of the information 23 may be used.

The protective layer 25 is formed by attaching a film made of a synthetic resin such as PP or PE to the surface of the blindfold layer 20 via an adhesive or the like, or laminating the above film to a blindfold seal. Can be. The protective layer 25 can of course be laminated on the surface of the blind layer 20 even when the information 23 is not formed on the surface of the blind layer 20.

By forming this protective layer 25,
There is no possibility that the blindfold layer 20 is damaged due to being overwhelmed or the blindfold layer 20 is rubbed and peeled off, and the concealing property can be reliably maintained until the blindfold layer 20 is peeled off.

In the blind seal 11 of the present invention, since the blind layer 20 can be easily peeled off from the carrier layer 19, it can be rubbed with a nail or a coin, or a tape or the like can be attached to the blind layer 20 and peeled off. Can be easily removed. Further, in the blindfold seal 31 in which the protective layer 25 is formed on the surface of the blindfold layer 20, one end of a tape or the like is attached to the protective layer 25 and the other end of the tape is pulled, thereby utilizing the adhesive force of the tape. Therefore, the blindfold layer 20 can be easily removed at the same time as the protective layer 25.

(2) Next, a method for manufacturing the blind seal supply sheet of the present invention will be described.

Blind seal supply sheet 1 shown in FIGS.
2 is manufactured as follows.

[0038] The blind seal supply sheet 12 is provided by the A.I. As shown in the figure, a release layer 15, a re-adhesive layer 17, and a transparent carrier layer 19 are sequentially laminated on the surface of the mount 13, and a blindfold layer 20 is formed on the surface of the carrier layer 19 by printing by screen printing. Is done. As shown in FIG. 3B, the thus formed product is subjected to press punching (for example, half-cut in seal printing, leaving the carrier layer 19 little by little (usually 1 to 2 mm) on the outer peripheral side of the blindfold layer 20). A cut 18 is made up to the re-adhesion layer 17 by Thomson processing in offset printing or the like. Then, in FIG. As shown in the figure, the extra re-adhesive layer 17 / transparent carrier layer 19 is removed.

The extra re-adhesive layer 17 / transparent carrier layer 19 does not need to be removed, and may be left in a notched state. Further, in the case of the blind seal 31 in which the protective layer 25 is formed on the surface of the blind layer 20, a protective layer having the same size as the mount is laminated from the front side of the blind layer 20, and, as described above, A notch is formed up to the re-adhesion layer by press punching or the like.

The same applies to the other examples of the seal supply sheet described above, but in the case of the seal supply sheet 12A,
As shown in FIGS. 6 and 7, a notch 18 is made up to the re-adhesive layer 17 while leaving the blindfold layer 19 little by little (usually 1 to 2 mm) on the inner peripheral side of the blindfold layer 20. In this case, usually, the re-adhesive layer 1
7 / Transparent carrier layer 19 is left.
