Description

The present invention relates to a card used for a credit card, a cash card, a point card, an employee card, and the like, and particularly relates to a glitter card having a unique metallic glitter. This unique radiance is sometimes referred to as “lame” or “lame sensation”, but a glittering material is used on part or the entire surface of the card surface so that the glittering material can effectively exhibit the radiance. The present invention relates to a glitter card having a printed layer.
“Lame” means “lame” in English, and originally means “golden” (woven fabric in which metal yarn is woven together with silk, hair, etc.).

In the card industry, there is a premium card called “platinum card”, which has gained popularity among users because of its unique radiance and color tone.
This card is a card without a magnetic tape, and a so-called “lamé printing ink” is printed between a core sheet and an oversheet as a sample. However, in the Japanese market, it is necessary to provide a JIS II specification magnetic tape on the outermost surface of the card, and it is necessary to provide a card in which this magnetic tape is concealed by a printing layer due to the problem of design. This is because the magnetic tape has a black or brown color derived from the color of the magnetic powder, and restricts the degree of freedom of card design.

Therefore, when “lame printing ink” is used for the concealment card, it is necessary to form a printing layer on the magnetic tape, and the specification of the sample cannot be adopted as it is.
Furthermore, for the convenience of forming a printed layer on magnetic tape, it is necessary to consider the magnetic properties, and the average particle size and ink film thickness of the ink pigment that can be used are limited, and special metallic glitter as shown in the sample There was a problem that could not reproduce the glitter.

Here, we will examine and examine the conventional specifications of a card with glitter.
FIG. 5 is a diagram showing the printing specifications of a glitter card without a magnetic tape, and FIG. 6 is a diagram showing the layer structure of another glitter card having a magnetic tape.
In the case of FIG. 5, the card specification relating to the above sample is shown, but the lame print layer 2 is provided between the core sheet 11 and the oversheet 13. Here, the lame print layer refers to a print layer that includes a coarse-grained metal material or the like and exhibits glitter. A lame agent is also added to cosmetics and the like, but a wide range of agents expressing the same glitter effect are used.
As shown in FIG. 5, when the magnetic tape is not provided, the lame printing layer 2 can be formed under the oversheet 13 and no concealing printing is required, so that the expression of glitter can be made relatively easy.

  On the other hand, when the oversheet 13 is provided with the magnetic tape 5 as shown in FIG. 6, the concealed silver print layer 4 is provided and the lame print layer 2 is provided thereon. In the specification in which 2 is the top layer, a unique radiance was not obtained. When the thickness of the lame print layer 2 is increased in order to further enhance the glitter, the necessary thickness of the lame print layer 2 needs to be about 15 μm, and sufficient luminance cannot be obtained. It has been observed that the readability of magnetic properties is reduced.

By the way, although the thing like patent document 1 and patent document 2 is detected in the prior art which expresses such a brilliant feeling, the thing directly related to this application cannot be found.
Patent Document 1 is characterized in that a glittering chip is sandwiched between a printed layer and a protective layer of a card, and the chip uses a crushed hologram foil. Thus, it is different from those using metal particles. Also, there is no description about hiding the magnetic tape. In Patent Document 2, a glittering layer in which a glittering pigment is dispersed in a transparent resin is laminated on a card substrate, and a concealing pigment is contained in the transparent resin on the glittering layer. A card comprising a concealing layer pattern layer composed of an image line part and a non-image line part for concealing an image is described, but the purpose of the card is a dye provided on the card surface It is intended to prevent tampering of the receiving layer and has a different purpose and configuration from the glitter card of the present application.

  Patent Documents 3 and 4 propose a magnetic recording medium in which a reproduction output and resolution are not reduced in a recording medium in which a concealing layer is formed on a magnetic recording layer. However, it is different from the one in which the concealing layer is formed as in the present application and the glittering feeling of the card is pursued.

Japanese Patent Laid-Open No. 10-250268 JP 2001-171272 A JP 2001-126241 A JP 2003-22516 A

  Therefore, the present invention provides a glitter print layer on a concealed print layer for concealing the magnetic tape in a configuration having a magnetic tape on the oversheet of a card composed of a core sheet and an oversheet, thereby providing sufficient glitter. The present invention has been completed through research.

  The first of the gist of the present invention to solve the above-mentioned problems is to have an oversheet transferred so that the magnetic tape becomes the outer surface of the card on the outer surface of the core sheet, and silk screen printing on the oversheet and the magnetic tape surface. A glittering card, wherein a concealed silver printing layer, a white ink printing layer, and a lame printing layer are sequentially formed.

  The second of the gist of the present invention has an oversheet on which the magnetic tape is transferred to the outer surface of the core sheet so as to be the outer surface of the card, and a concealed silver printing layer by silk screen printing on the oversheet and the magnetic tape surface. And a white ink printing layer, and a glitter printing layer, and a glittering card, wherein a printing layer by offset printing that partially conceals the glitter printing layer is formed.

  The glitter card of the present invention has a magnetic tape on the surface of the card, conceals the magnetic tape, and further has a glitter printing layer on the concealment layer, so that it can exhibit a sufficient glitter feeling. it can.

The glitter card of the present invention will be sequentially described with reference to the drawings.
FIG. 1 is a diagram showing a layer configuration of an embodiment of a glitter card according to the present invention, FIG. 2 is a diagram showing a layer configuration of another embodiment of the glitter card, and FIG. 3 is a diagram used for a lame print layer. FIG. 4 is a diagram showing a micrograph of silver, and FIG. 4 is a diagram showing a micrograph of ordinary concealed silver.

As shown in FIG. 1, the glitter card of the present invention has core sheets 11 and 12 as a central layer, and transparent oversheets 13 and 14 are laminated on both surfaces thereof. The transparent oversheets 13 and 14 include the transferred magnetic tapes 5 and 6, but the magnetic tape 6 on the transparent oversheet 14 side is not essential. The glitter card 1 of the present invention has an oversheet 13 on which a magnetic tape 5 is transferred to a core sheet 11 so as to be on the outer surface of the card, and the concealed printing layer 4 and the surface of the oversheet 13 and the magnetic tape 5 This is because a configuration in which the white ink printing layer 3 is provided and the lame printing layer 2 is provided after concealing the magnetic tape 5 is targeted.
Moreover, although the core sheets 11 and 12 have shown the state using two sheets, the single layer core sheet corresponded to the total thickness of two sheets may be sufficient.

The transparent oversheet 13 and the surface of the magnetic tape 5 are provided with a masking silver printing layer 4 by silk screen printing, and the white ink printing layer 3 is provided on the masking silver printing layer 4 surface.
The concealing silver printing layer 4 is for concealing the black or brown color inherent to the magnetic tape 5 as described above, and is generally concealed for ordinary magnetic cards. It is printing. Actually, the masking silver printing layer 4 is printed with printing ink containing metal aluminum powder. A general aluminum powder for concealment printing is obtained by pulverizing an aluminum foil having a thickness of 1 to 2 μm or less, and a fine powder having an average particle diameter of about 8 to 10 μm is used. However, the average particle diameter here means the size of the shape when the fine powder is projected in a plane, and does not mean the diameter of the spherical particles. The same applies to an aluminum powder for lame printing described later.
The film thickness of the concealed silver print layer 4 is preferably about 2 to 3 μm after drying. If it is less than 2 μm, a sufficient hiding effect may not be obtained. However, if it is too thick, it affects magnetic readability. In the case of screen printing, it is preferable to print on a fine mesh screen.

The white ink printing layer 3 has an effect of concealing the magnetic tape 5, but it is also intended to enhance the glitter of the lame printing layer 2 by reflecting external light received by the card. For the printing of the white ink printing layer 3, it is preferable to use an ink having a relatively high hiding density even if it is a white ink, and a white pigment made of titanium oxide is used.
White ink printing is preferably performed by silk screen printing, but may be offset printing. For example, a predetermined effect can be obtained by printing “white for UV carton transfer” ink manufactured by The Inktec Co., Ltd. in two colors (printing with a thickness of 1 μm × twice).
The printed film thickness of the white ink printing layer 3 is preferably about 2 to 4 μm after drying. If it is too thick, it affects magnetic writing and readability. In the case of screen printing, it is preferable to print on a screen having a fine mesh.

The lame print layer 2 is printed on the white ink print layer 3. The lame printing layer is a portion that exhibits unique glitter. However, in order to increase the glitter, it is preferable to perform thick printing, and similarly, printing is performed by silk screen printing. In general, in screen printing, the “glue” of ink becomes thinner as the mesh number of the screen becomes finer. The aluminum powder particle size of the lame printing ink may be large, and it is preferable to use a coarse screen mesh for the screen plate as compared with the case of concealed silver printing or white printing.
For printing ink, a paste made of metal aluminum having a large particle size is dissolved in a vehicle (binder) and used as an ink. The particle diameter of the metal aluminum is preferably about 25 to 40 μm. If it is less than 25 μm, the glitter feeling is not sufficient, and if it is 40 μm or more, it is too coarse and a uniform printed surface cannot be obtained.

It is preferable to increase the printing film thickness of the lame printing layer 2 in order to increase the glitter. However, when the film thickness is too large, there is a problem that the reproduction output and the resolution when reading with the magnetic head are lowered.
In the case of a normal concealed magnetic card with only one colored layer, the thickness of the ink layer is about 0.5 to 5 μm, but in the case of the glitter card of the present application, three or four ink layers This is because the total thickness becomes 10 μm or more.
Therefore, it has been confirmed that the print thickness of the lame print layer 2 is limited to 5 to 6 μm even in combination with a high resolution magnetic tape.

  In the glitter card of the present invention, an appropriate printing layer 7 can be provided on the lame printing layer 2 by offset printing or the like, as shown in FIG. For example, black solid printing or the like can be performed so that the lame printing layer 2 can be partially seen. In that case, if the partial white printing 8 by offset printing is performed before the appropriate printing layer 7 by the offset printing, the brightness of the lame printing can be suppressed only in that portion, and the variation in design can be abundant. . Without the white printing, the brightness of the lame printing may not be sufficiently suppressed.

(Embodiments related to materials used)
The metal aluminum powder used for lame printing ink is preferably larger in size than that used for ordinary concealed silver printing. This is because coarse particles produce strong glitter.
FIG. 3 shows an image having a maximum particle size of 30 to 34 μm printed on a card substrate, magnified 60 times, and photographed under a microscope. It is recognized that the grain size is larger than that of the ordinary concealed silver of FIG. 4 taken in the same manner.

Binders (resins) for converting lame printing ink (and other screen inks) into silk screen printing inks include vinyl chloride / vinyl acetate copolymer, vinyl chloride / vinyl acetate / vinyl alcohol copolymer. Various resins such as vinyl chloride / vinyl acetate / maleic acid copolymer, fiber resin, acrylic resin, vinyl chloride / acrylate copolymer, bisphenol A type epoxy resin, and the like can be used.
Specifically, an ink using a silver paste “606H” manufactured by Seiko Advance Co., Ltd. or an ink using a silver paste “SPA650N” manufactured by The Inktech Co., Ltd. can be used. Different materials usually give a different color tone and brightness even if the ink composition and printing conditions are the same.

As the magnetic tape material, a transfer material is usually used. In this case, a magnetic material is applied to a thin plastic sheet so as to be peeled off or vacuum-deposited so that it can be thermally transferred to a card substrate. The thin plastic sheet is peeled and removed after the card substrate is heated and transferred, so that the magnetic layer of the magnetic material is embedded in the card substrate.
As described in Patent Document 3, Patent Document 4, etc., as a magnetic recording material that does not reduce reproduction output or resolution through a thick concealing layer as in the present invention, a hexagonal system with a high squareness ratio. It has been proposed to use a ferrite material or a barium ferrite material. Also in the glitter card of the present application, it is preferable to use a transfer tape made of such a high-resolution magnetic material.

  In general, when the recording / reproduction is performed with the average peak voltage of the reproducing head output signal at a recording density of 20 magnetic flux reversals / mm being recorded under the same conditions as shown in JIS X6302 (8.3.1) except for the recording density. It should be 70% or more of 8 magnetic flux reversal / mm (JISX6302 (8.3.2)). If it is a magnetic tape etc. which were used for the below-mentioned Example, the numerical value of the said specification can be satisfy | filled.

Materials for the core sheet and transparent oversheet include polyvinyl chloride, PET-G (copolymerized polyester resin in which part of the ethylene glycol component in polyethylene terephthalate is substituted with cyclohexanedimethanol), and acrylonitrile-butadiene-styrene copolymer resin. Resins such as (ABS), polypropylene, polycarbonate, polyimide, polyamide, and triacetate can be used.
In many cases, the core sheets 11 and 12 are filled with a white pigment for the purpose of enhancing concealability. The thickness of the core shear is about 0.54 to 0.65 mm in the case of a single layer, and about 0.27 to 0.30 mm in the case of two layers. However, since the total thickness of the card is 0.76 ± 0.08 mm defined by ISO 7810 (JISX6301), it varies depending on the thickness of the oversheets 13 and 14 to be used.

An embodiment of the present invention will be described with reference to FIGS.
Two core hard vinyl chloride sheets ("VSS3197" (thickness: 0.28 mm)) manufactured by Sumitomo Bakelite Co., Ltd. are used as the core sheets 11 and 12, and Taihei Chemical Co., Ltd. is manufactured as the transparent oversheets 13 and 14. Two transparent hard vinyl chloride sheets ("M1063" (thickness: 0.10 mm)) were used.

In addition, a magnetic tape of “Memory Dick T-1202” manufactured by Dainippon Ink Co., Ltd., which uses a barium ferrite-based material with high resolution and high coercive force on the outer surface side of the card of the transparent oversheets 13 and 14. 5 and 6 are previously transferred.
The laminated body of the core sheets 11 and 12 and the oversheets 13 and 14 is sandwiched between mirror plates made of chrome-plated steel plates and hot-pressed (120 ° C., 38.4 kgf / cm ² , 120 seconds), and integrated. A card substrate was used.

On the card substrate, the concealed silver ink having the following contents was first printed by silk screen printing on the magnetic tape 5 transfer surface of the oversheet 13. The printing conditions were such that a 350 mesh plate was used and the film thickness after drying was 2 μm. The concealing silver ink is actually a printing ink obtained by dissolving aluminum powder in a binder.
