Description

The present invention relates to thick plastic cards such as cash cards, credit cards, various membership cards, etc., and more particularly to cards with metallic texture and excellent design and security.

Conventionally, a card is known in which a core base material, a base material, a masking layer, a fluorescent print layer, a metal deposition layer, a pattern print layer, and a protective layer are sequentially laminated (see Patent Document 1).

As a result, the latent image composed of the fluorescent pigment cannot be seen under normal circumstances, and the fluorescent pattern can be seen only when irradiated with ultraviolet rays having a specific wavelength. Authenticity can be determined with reliability.

However, in the above card, the fluorescent light diffuses in many directions, and although the metallic texture can be expressed, the fluorescent pattern becomes unclear at the boundary, and the fluorescent pattern recognition performance is insufficient.

In the following, the invention will be explained in detail on the basis of the figures.

In the embodiment of the card of FIG. 1, a substrate layer 11, a patterned fluorescent printed layer 13, a patterned black printed layer 14, and a metal vapor deposition layer 15 are laminated in order, and the pattern of the fluorescent printed layer 13 and the The pattern of the black printed layer 14 is complementary, and the black printed layer 14 is provided in the region without the fluorescent printed layer 13 .

As for the positional relationship, as shown in FIG. 10, the pattern of the black printed layer 106 exists in the area without the pattern of the fluorescent printed layer 103, and conversely, the pattern of the black printed layer 106 exists in the area with the pattern of the fluorescent printed layer 103. There is a black printed layer non-pattern portion 107 where no pattern exists.

In this card, a front oversheet 12 is provided between the base layer 11 and the patterned fluorescent printed layer 13 and the patterned black printed layer 14, and the patterned fluorescent printed layer 13 and the patterned black printed layer 14 of the base layer 11 are provided. A backing oversheet 16 is provided on the opposite side of the black printed layer 14 .

The pattern of the fluorescent printed layer and the pattern of the black printed layer may be laminated so as to overlap in the boundary region even if they are not complementary. must exist.

Such a card cannot be visually recognized from the surface due to the metal vapor deposition layer 15 under a normal environment where the intensity of the ultraviolet rays of sunlight is high. The pattern of layer 21 can be recognized and distinguished from the pattern of black printed layer 22 .

The substrate layer 11 that can be used in the present invention includes polyethylene terephthalate (PET, PET-G), polyvinyl chloride (PVC), polycarbonate (PC), vinyl chloride/vinyl acetate copolymer, acrylonitrile/butadiene/styrene copolymer. Resin sheets such as polymer (ABS) resin and environment-friendly polylactic acid can be used.

The fluorescent print layer 13 according to the present invention is made of a fluorescent print layer composition containing a fluorescent material, a binder resin, and a solvent. Both fluorescent dyes and fluorescent pigments can be used as the fluorescent material, but fluorescent pigments are preferred because of their superior durability and long-term reliability.

The fluorescent pigment contained in the fluorescent printing layer 13 is preferably a fluorescent pigment having a particle diameter of 7 to 8 μm, and the blending ratio to the binder resin is 1 to 10% by mass, and the thickness of the printing layer is 2 to 10 μm. is preferred. The fluorescent printed layer 13 formed in this range can emit fluorescence when irradiated with ultraviolet rays having a specific wavelength, even if it is covered with a highly concealing metal vapor deposition layer 15 laminated thereon. The fluorescent pattern by the fluorescent printed layer 13 can be clearly confirmed visually. If the thickness is out of this range, the shielding property of the metal deposition layer 15 is superior, and the fluorescent pattern cannot be visually confirmed under the above conditions.

Further, the fluorescent print layer 13 is preferably patterned with a halftone dot area ratio of 80 to 100%. When the halftone dot area ratio exceeds 80%, even when covered with the metal vapor deposition layer 6 and the pattern printed layer 7 with high hiding properties, it is possible to emit clear fluorescence when irradiated with ultraviolet rays having a specific wavelength. If the halftone dot area ratio is less than 80%, the metal vapor deposition layer 6 and the pattern printed layer 7 have a strong concealing property, and the visibility may be insufficient, which may make it impossible to make a correct authenticity determination.

The metal deposition layer 15 according to the present invention imparts a metallic texture, and the surface shape may be flat or uneven.

As the metal material used for the metal vapor deposition layer 15, single metals such as aluminum, tin, iron, chromium, cobalt, nickel, gold, and silver, or mixtures thereof can be used.

Although the method for obtaining the metal deposition layer 15 is not limited, for example, a transfer method can be used. Specifically, separately, a substrate film with a flat surface is formed with an uneven shape, and a peeling protective layer, a metal vapor deposition layer, and an adhesive layer are sequentially laminated to prepare a transfer body, and then, on the exterior substrate. can be obtained by thermal pressure transfer.

As the front oversheet layer 12 and the back oversheet layer 16, the same material as that of the substrate layer is usually used, but a transparent material having a thickness of about 0.05 to 0.1 mm is often used.

The black printed layer 14 according to the present invention can be directly printed using a general-purpose printing method such as gravure printing, screen printing, flexographic printing, offset printing, or indirectly by transferring a printed layer once printed to a transfer film or the like. It is also possible to form a picture pattern. The printing ink is not particularly limited as long as it has ink properties suitable for the printing method used and excellent durability after printing. For example, UV curable ink can be used. The printing film thickness is preferably 1.0 to 2.5 μm.

The fluorescent reflection layer is preferably white or silver in color and is preferably screen-printed to a thickness of 1.0 to 2.5 μm. When the white ink is used in this case, it is composed of a white printing layer composition containing a white pigment, a binder resin and a solvent, and the white pigment is preferably contained in an amount of 20 to 70% by weight based on the binder resin. In the case of silver ink, it is preferable to use an ink coated with aluminum powder having a film thickness of 1 to 2 μm and a maximum length of 6 to 8 μm. If the aluminum powder is out of this range, the hiding power may be insufficient, or the action of the magnetic layer may be deteriorated due to excessive hiding. The aluminum powder can be obtained by various methods, and among them, a method of vacuum-depositing aluminum onto a thin film, peeling off the obtained vapor-deposited film, and pulverizing the film is preferable.

If necessary, a magnetic tape can be provided on the metal vapor deposition layer side of the base material layer 11 or on the metal vapor deposition layer side of the front oversheet layer 12 . The magnetic tape is temporarily adhered to the base layer 11 or the front oversheet layer 13 in advance, and is embedded by lamination by hot pressing. In this case, separately, a magnetic recording layer composition comprising a magnetic powder, a binder resin, a solvent, and, if necessary, a surfactant and other auxiliary agents is applied to the substrate film by a known method, followed by orientation treatment, Obtained by drying. As the magnetic powder, γ-iron oxide, magnetite, cobalt-coated iron oxide, and the like can be used.

Moreover, it is also possible to provide a protective layer on the outer surface side of the metal vapor deposition layer as needed. In this case, it is provided to prevent the surface from being scratched or stained when the card is used for magnetic tape reading or the like. The protective layer is made of conventionally known thermoplastic resins such as acrylic resins, urethane resins, polyester resins, vinyl chloride/vinyl acetate copolymer resins, thermosetting resins, and ionizing radiation curable resins.

The protective layer can be formed by directly printing a composition containing the above resin using a general-purpose printing method such as gravure printing, screen printing, flexographic printing, or offset printing, or once formed on a transfer film or the like, and then transferred. It is also possible to form a protective layer indirectly. Especially in the case of transfer, it can be formed together with other layers. The film thickness is preferably 1.0 to 2.5 μm in consideration of durability.

When a magnetic tape is provided, it is common to provide a masking layer in an area where the fluorescent print layer 13 is not present. It is preferable to form it with the ink which was applied. If the aluminum powder is out of this range, the hiding power may be insufficient, or the action of the magnetic layer may be deteriorated due to excessive hiding. The aluminum powder can be obtained by various methods, and among them, a method of vacuum-depositing aluminum onto a thin film, peeling off the obtained vapor-deposited film, and pulverizing the film is preferable.

In addition, it is possible to provide a pattern printed layer on the outer surface side of the metal vapor deposition layer 15, and it is possible to directly print using a general-purpose printing method such as gravure printing, screen printing, flexo printing, offset printing, or to a transfer film. It is also possible to indirectly form a pattern by transferring a printed pattern printed layer. The printing ink is not particularly limited as long as it has ink properties suitable for the printing method used and excellent durability after printing. For example, UV curable ink can be used. The printed film thickness of the pattern printed layer is preferably 0.5 to 2.0 μm.
