It is a card | curd which shows one Embodiment of this invention. It is a card | curd which shows other embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 shows a card according to an embodiment of the present invention. A card main body 2 in which an ink-jet ink receiving layer 5, an ink-jet recording unit 6, and a protective layer 7 are laminated on a substrate 4 in this order, and an opaque group. The concealment label 3 having the individual information recording portion 10 on one surface of the material 8 and the pseudo adhesive layer 9 provided on the other surface of the opaque base material 8 includes the protective layer 7, the pseudo adhesive layer 9, and the like. Is a configuration of the card 1 bonded in a peelable manner. The recording unit for the individual information to be recorded on the opaque base material is only required to be able to record variable information by an electric signal such as inkjet recording, thermal transfer recording, electrophotographic recording, and the like.

  FIG. 2 is a card showing another embodiment of the present invention, in which a receiving layer 5 for inkjet ink is provided on a substrate 4, and a pattern printing unit 11 is formed on the receiving layer 5 by offset printing or the like. In addition, an ink jet recording portion 6 is formed on the receiving layer 5, and the card body portion 2 in which the protective layer 7 is laminated so as to cover the entire surface of the receiving layer 5, and one surface of the opaque base material 8, The tint block printing unit 12 is formed by offset printing or the like, has the individual information recording unit 10 on the tint block printing unit 12, and has a pseudo adhesive layer 9 provided on the other surface of the opaque base material 8 It consists of label 3. The card body 2 and the concealment label 3 are the card 1 in which the protective layer 7 and the pseudo adhesive layer 9 are detachably bonded. In FIG. 2, although the inkjet recording part 6 and the pattern printing part 11 do not overlap, an inkjet recording part can be formed on the pattern printing part on the inkjet ink receiving layer. In FIG. 2, the opaque base tint pattern printing unit 12 is formed on one entire surface of the non-transparent base. However, a partial tint pattern printing unit is provided on one surface of the opaque base. Can do.

  Compared with the card shown in FIG. 1, the card 1 shown in FIG. 2 is provided with a pattern printing layer 11 on the ink-jet ink receiving layer 5, and further on the opaque base material 8 with a background pattern. The difference is that the printing unit 12 is provided. Although FIG. 2 shows that the tint block printing portion 12 is formed on one whole surface of the opaque base material 8, the present invention is not limited to this, and the tint block printing portion is partially formed on one surface of the opaque base material. May be. In addition to the card shown in FIGS. 1 and 2, for example, a back layer is provided on the surface opposite to the surface of the base material on which the ink-jet ink receiving layer is provided, and ink-jet recording is performed separately on the concealed label surface. It is possible to improve the printer transportability in recording information, and to provide functions such as preventing the front and back surfaces of the cards from adhering (blocking) when a large number of cards are stored.

Each layer which comprises the card | curd of this invention is demonstrated in detail below.
(Base material)
As long as the base material 4 in the card body 2 holds the ink-jet ink receiving layer and the protective layer 7 and does not interfere with the ink-jet recording means and the individual information recording means in a state where the concealment label is laminated. The material constituting the substrate is not limited. For example, synthetic resins such as vinyl chloride, vinyl chloride-vinyl acetate copolymer, PMMA, PET, ABS, polyolefin, PET-G, polycarbonate, acrylonitrile-styrene copolymer, cellulose propionate, and cellulose acetate butyrate are used. .

  In addition, a print layer may be provided on the base material by printing a pattern, a pattern, a character, or the like of a desired design by, for example, silk screen printing or offset printing. A substrate having a thickness of 20 to 500 μm is used.

(Receiving layer for inkjet ink)
The ink-jet ink receiving layer 5 formed on the substrate is not limited as long as it can form an ink-jet recording portion as secret information hidden by the concealment label. However, in order to obtain a high-quality recorded image, it is a void-type receiving layer provided with a fine porous layer containing a hydrophilic polymer and a pigment as a receiving layer excellent in absorbability and drying property of inkjet ink. It is preferable. As the ink-jet ink for recording on such a receiving layer, conventionally known dye-type ink, pigment-type ink, or the like can be used.

  Examples of the pigment used in the receiving layer include light calcium carbonate, heavy calcium carbonate, magnesium carbonate, kaolin, clay, talc, calcium sulfate, barium sulfate, titanium dioxide, zinc oxide, zinc hydroxide, zinc sulfide, and zinc carbonate. , Hydrotalcite, aluminum silicate, diatomaceous earth, calcium silicate, magnesium silicate, synthetic amorphous silica, colloidal silica, alumina, colloidal alumina, pseudoboehmite, aluminum hydroxide, lithopone, zeolite, magnesium hydroxide, The primary particles can be used as they are or in a state where secondary agglomerated particles are formed. In particular, it is preferable to use silica, colloidal silica, and pseudoboehmite synthesized by a gas phase method having an average particle diameter of 100 nm or less.

  As the hydrophilic polymer, polyvinyl alcohol is preferable. In addition to normal polyvinyl alcohol obtained by hydrolyzing polyvinyl acetate, polyvinyl alcohol having a cation-modified terminal can be used. In addition, in the receiving layer, various additives such as boric acid or a salt thereof for improving the film forming property of the receiving layer and increasing the film strength, and a cationic mordant for increasing water resistance and moisture resistance after recording are included. It can also be added. Using the receiving layer coating solution thus adjusted, the receiving layer can be formed on the substrate by a known method such as gravure printing, screen printing, or bar coating. The thickness of the receiving layer is about 5 to 30 μm in a dry state.

(Protective layer)
The protective layer 7 protects information recorded on the ink-jet ink receiving layer, and further prevents the ink-jet recording part and the picture printing part from being taken to the label side when the label is peeled off from the pseudo-adhesive layer of the concealment label. To do. The protective layer is preferably made of a resin, and a resin composition that can exhibit a desired protective function is preferably selected. In general, cellulose derivatives such as ethyl cellulose, nitrocellulose, and cellulose acetate, acrylic resins such as polymethyl methacrylate, polyethyl methacrylate, and polybutyl acrylate, polyvinyl chloride, vinyl chloride vinyl acetate copolymer, polyvinyl Thermoplastic resins such as vinyl polymer thermoplastic resins such as butyral, unsaturated polyester resins, polyurethane resins, and amino alkyd resins can be used.

  Moreover, in order to obtain a highly durable protective layer, it is preferable to form an ionizing radiation curable resin by curing. The curable resin that is cross-linked by ionizing radiation is, for example, a resin containing a monomer / oligomer having a functional group that is polymerized (cured) by ionizing radiation such as ultraviolet (UV) or electron beam (EB). In particular, it is preferable to use an ultraviolet curable resin as a means for easily curing without using a large-scale apparatus as a curing condition. If necessary, an additive is added to the above resin, and a solvent is added, and a protective layer having a thickness of about 0.1 μm to 10 μm is formed by a known method such as offset printing or gravure printing.

(Opaque substrate)
As the opaque base material 8 constituting the concealment label, the ink jet recording part of the card body part is concealed so that the ink jet recording part cannot be read even when viewed through the card with the concealment label attached. It is a base material having properties. As the opaque substrate, a white substrate can be used, a substrate made of a resin film can be used, a white resin film containing a white colorant in the resin substrate, the white resin film or the transparent resin film, etc. A white coat film in which a white coat layer is provided with a white ink or the like on at least one surface layer of the resin film can be used.

  As the white resin film, a resin film containing a white colorant can be used, and specific examples include a white polyethylene terephthalate film, a white polyolefin film, and a white polystyrene film containing a white colorant. The white colorant to be added is not particularly limited, and publicly used white colorants such as titanium dioxide, barium sulfate, calcium carbonate, silica, talc, and clay can be used. As a white coloring method, not only adding a white colorant, but also adding a resin incompatible with a polyester resin such as polymethylpentene to a polyethylene terephthalate film, biaxially stretching, and fine bubbles inside You may use together the method of forming.

  As the opaque base material, the white base material has been described, but the “white” does not have to be pure white, including hues such as gray and yellow, and can be almost white, and is recorded on the opaque base. This is to make the information recording part easy to read. The opaque substrate has a thickness of 20 to 500 μm.

(Pseudo adhesive layer)
The pseudo-adhesive layer 9 in the present invention is formed so that the card body and the opaque base material are in close contact with each other so that they can be peeled off, and the peeled surface after peeling is not sticky and cannot be re-tacked. The pseudo adhesive layer can be composed of a pressure sensitive adhesive and a pigment. Examples of pressure-sensitive adhesives include resins such as acrylic polymers, natural rubber, ethylene-vinyl acetate copolymers, acrylonitrile-butadiene copolymers, styrene-butadiene copolymers, polyisobutylene, and polyvinyl ether. Is mentioned. A pigment is used in the pseudo adhesive layer in order to adjust the adhesive strength. Specifically, the pressure-sensitive adhesive alone has a high adhesive strength, and when the concealment label is peeled off from the card body, the ink jet recording part and the picture printing part are pulled by the pseudo adhesive layer, and the label side It will be taken. Furthermore, there is a problem that after the concealment label is peeled off from the card body part and the secret information is stolen, it is attached to the card body part again. Therefore, a pigment is added to the pressure sensitive adhesive to reduce the adhesive strength.

  Examples of the pigment include inorganic pigments such as kaolin, talc, calcium carbonate, aluminum hydroxide, and amorphous silica, and organic pigments such as urea-formalin resin filler, raw starch, and pulp powder. In addition, fillers such as stearamide and zinc stearate can be added as pigments. It is preferable to adjust the pressure sensitive adhesive by adding about 50 to 200% by mass, preferably about 80 to 150% by mass. When the amount of the pigment added is small, the adhesive force of the pseudo adhesive layer increases, and after the concealment label is peeled off, the concealment label can be re-adhered to the card body with the pseudo adhesive layer. This is a security issue. Moreover, when there is too much addition amount of the said pigment, the adhesiveness at the time of sticking a concealment label on a card | curd main-body part is low, and there exists a possibility that a concealment label may peel off accidentally during handling.

Applying and drying a coating liquid obtained by dissolving or dispersing the material constituting the pseudo-adhesive layer in water or an organic solvent onto an opaque substrate so that the coating amount after drying is about 10 to 40 g / m ^2. Thus, a pseudo adhesive layer is formed.

  The recording unit 10 for individual information provided on the opaque base material is not limited to a recording method as long as variable information can be recorded by an electric signal such as ink jet recording, thermal transfer recording, and electrophotographic recording. The copy-forgery-inhibited pattern printing unit 12 is formed on an opaque base material by an offset printing or the like with an image such as a copy-forgery-inhibited pattern or a pattern such as a line. It is also possible to record and form the tint block printing portion by a recording means for forming a recording portion for individual information.

  On the ink-jet ink receiving layer, the pattern printing unit 11 can be formed by offset printing or the like. The pattern printing portion and the ink jet recording portion may overlap at some places, but it is preferable to provide the ink jet recording portion directly on the ink jet ink receiving layer because the recording fixability is improved. . It is also possible to form the pattern printing layer with the same recording means as the ink jet recording means in which the ink jet recording portion is formed.

The card of the present invention will be described in more detail with reference to examples. In the text, “part” or “%” is based on mass unless otherwise specified.
Example 1
A polyethylene terephthalate resin film (manufactured by Toray Industries, Inc.) having a thickness of 250 μm is prepared as the base material 4, and a vinyl chloride-vinyl acetate copolymer and a urethane acrylate resin (ultraviolet curable resin) are provided on one surface of the base material. In order to make the thickness of 2 μm, apply a roll coating method with a prepared ink (primer manufactured by DNP Fine Chemical Co., Ltd.) and dry with ultraviolet irradiation. An anchor layer was formed on. By gravure printing using a coating liquid for inkjet receptive layer (made by Takamatsu Yushi Co., Ltd., product name MZ-477 diluted with a solvent) in which fine silica and polyurethane resin are mixed on the anchor. The ink-jet ink receiving layer 5 was formed so that the dry thickness was 20 μm.

  Next, offset printing was performed on the above-described ink-jet ink receiving layer 5 using ultraviolet curable ink (blue), and the pattern printing section 11 was formed by ultraviolet irradiation and drying as shown in FIG. In addition, by using a commercially available Epson inkjet printer, personal information (date of birth) and secret information of a personal identification number are printed on the receiving layer 5 with a black inkjet recording ink. The recording part 6 was formed. As shown in FIG. 2, UV L carton OP varnish (manufactured by T & K TOKA) is offset printed as a protective layer ink on the entire surface of the ink-jet ink receiving layer on which the pattern printing portion and the ink jet recording portion are formed. The card body portion was prepared by irradiating with ultraviolet rays and drying, and providing a protective layer 7 having a thickness of 8 μm at the time of drying.

  A white polyethylene terephthalate having a thickness of 125 μm is used as an opaque base 8, offset printing is performed on one surface of the opaque base 8 using an ultraviolet curable ink (yellow color), irradiation with ultraviolet rays, and drying are performed as shown in FIG. As shown in FIG. On the copy-forgery-inhibited pattern printing unit 12, the individual information of the address and name was printed with black inkjet recording ink using the above Epson inkjet printer to form the individual information recording unit 10. Using a pseudo-adhesive layer coating liquid having the following composition on the surface of the opaque base material 8 where the individual information recording unit 10 is not formed, the thickness upon drying is 20 μm by gravure printing. Before applying the pseudo-adhesive layer 6 and drying it, the concealment label is bonded and adhered to the card body so that the protective layer of the card body and the pseudo-adhesive layer are in contact with each other. The card of Example 1 was produced by punching.

(Coating fluid for pseudo adhesive layer)
100 parts of modified natural rubber latex with a solid content of 30% 30 parts of amorphous silica with an average particle diameter of 3 μm

  In the card of Example 1 produced above, the secret information inkjet recording part 6 is covered with the opaque concealment label 3 so that the information of the recording part cannot be recognized at all, and the concealing property is not obtained. It was good. In addition, since the concealment label is the same as the size of the card body and the card is made by stamping the two together, it is difficult to align and apply the blindfold label to conceal the recording part locally. It was easy to produce. Furthermore, the concealment label is the size of a card, and no step is produced in the concealment portion, which is easy to use. Further, after the concealment label is peeled off from the card body, the concealment label cannot be re-adhered, and a third party cannot see the ink jet recording part of the secret information, and the security is high. Furthermore, when the concealment label was peeled off with the obtained card, the person himself was able to confirm the secret information of the concealed ink jet recording unit. In addition, this card can recognize information including the individual information recording portion and the concealed inkjet recording portion on the surface of the concealment label, and can transmit information as a recording portion as compared with a normal card. The amount of information can be doubled, and the card is very useful.
