Abstract

(57) [Abstract] [PROBLEMS] To provide a card on which a printed matter having a high quality of images and characters is formed inexpensively in a short time even with a small number of copies regardless of a known printing method or printing method. A ribbon having a heat-fusible ink layer composed of a coloring material and a binder of wax and / or resin on the ink receiving layer of a card substrate in which a porous ink receiving layer is provided on at least one surface of a substrate. The above ink layers were brought into contact with each other and heated by a thermal head or the like to print images, characters and the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a card used for identification cards, driver's licenses, commuter passes, cash cards, IC cards and the like.

[0002]

[Prior art]

 Conventionally, the characters and images printed on the above card are printed by a very commonly known printing method such as offset printing, gravure printing, silk printing, etc., or Japanese Utility Model Laid-Open No. 5-31975. This is a method of printing using a thermal sublimation printer as disclosed in.

However, the above-mentioned conventional printing method requires a high printing plate cost when printing a small number or a part of an original image and requires a long time for the printing, which is very practical. I can't say that I can bear it.

[0006] Further, in the method of printing using a thermal sublimation printer, when characters are printed, the edges of the characters are softened and a clear expression cannot be performed, resulting in poor character quality. There is.

[0005]

[Problems to be solved by the device]

 In view of the above-mentioned conventional technique, the present invention is a card which forms a printed matter with high image and character quality at low cost in a short time even with a small number of copies, regardless of the above-mentioned known printing method and printing method. It is an issue to provide.

[0006]

[Means for Solving the Problems]

 The present invention has been made for the purpose of solving the above-mentioned problems, and a coloring material is provided on the ink receiving layer of a card substrate in which a porous ink receiving layer is provided on at least one surface of the card-shaped substrate. The ink layer of the ribbon having a heat-meltable ink layer composed of a wax and / or a resin binder is brought into contact with each other and heated by a thermal head or the like to print an image, a character or the like. is there.

That is, the inventor of the present invention has conducted extensive research in order to solve the above problems, and as a result, has formed a card substrate by providing a porous ink receiving layer on the surface of the substrate, The ink receiving layer of the ribbon is brought into contact with the ink receiving layer of the ribbon, and the ink layer of a ribbon having a heat-meltable ink layer made of a coloring material such as yellow, magenta, cyan, and black, and a binder of wax and / or resin When the binder of the ink receiving layer is melted by heating with a thermal head or the like, and an image or characters are printed by a heat-melting type printer in which the ink layer is melt-transferred onto the card surface, The inventors have learned that they can solve the above problems and completed the present invention.

The present invention will be described in detail below. The card of the present invention can be obtained as follows. The material used as the substrate is not particularly limited as long as it is a plastic film, but preferably used are polyethylene terephthalate, polypropylene, polyvinyl chloride, polystyrene, or foam films thereof. . Laminated paper obtained by laminating the above film on both sides of plain paper can also be effectively used.

Next, an ink receiving layer is provided on the above base material to form a card base, which may be provided by a conventionally known formulation that is compatible with the binder of the ink ribbon. However, in particular, when the formulation disclosed in Japanese Patent Laid-Open No. 62-197183 is used, the surface layer is formed porous, the cushioning property is good, and the reproducibility and gradation of the fine dots are fine. An excellent printed image of high quality is produced (this surface layer is marketed under the name of Pichikoto XE-W manufactured by Nisshinbo Industries, Inc.).

Further, this product can be remarkably improved in gloss on the surface of the card and on the printed product by heat-pressing after printing, and the abrasion property is also improved, so that it can be effectively used as a card. It becomes possible to do. Of course, after printing, a protective layer may be provided or a plastic film may be subjected to a laminating treatment for the purpose of protecting the surface.

Further, a fluorescent whitening agent may be added to the ink receiving layer to improve whiteness, and a light stabilizer or an ultraviolet absorber may be added to improve weather resistance.

The back surface of the card may be provided with minute concaves and convexes or porosity or may be coated with a thin lubricant for the purpose of improving the transportability to the hardware. By doing so, the usability is improved and it becomes extremely effective in use. As the above lubricant, polyethylene wax, polyethylene beads, etc. are effectively used. If a magnetic layer is provided, it can be used as a magnetic card.

[Operation and effect of the device]

 The present invention is as described above, and the card of the present invention uses a heat melting type printer for the ink receiving layer of the card substrate in which the porous ink receiving layer is provided on the surface of the substrate. Since it is composed by printing original images, characters, facial photographs, etc., it is possible to print the images, etc., at low cost in a short time even with a small number of copies or a part, and to express the outlines of images and characters clearly. It is possible to provide an excellent card with high image and character quality.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a surface view of an example of the card of the present invention, and FIG. 2 is a cross-sectional view taken along the line AA in FIG. The card layer 3 is formed by providing the receiving layer 2. 4 is an image formed on the ink receiving layer 2 and 5 is a character.

Example 1 Pichicoat XE-W (trade name) manufactured by Nisshinbo Co., Ltd. was coated on the surface of a substrate 1 made of a white polyethylene terephthalate film having a thickness of 188 μm to form a porous ink. The receiving layer 2 was formed to form the card substrate 3. An image containing a portrait photograph 4 and characters 5 is printed on the ink receiving layer 2 of the card base 3 with a heat-melting type full color printer, and a polypropylene film is laminated on both front and back surfaces of the card. The card of an example of the present invention was obtained.

This image had good reproducibility of fine dots, excellent gradation, and high image quality with good image and character quality.

Example 2 An ink receiving layer 2 was formed in the same manner as in Example 1 on one surface of a substrate 1 made of a foamed polyethylene terephthalate film having a thickness of 250 μm, and an image was printed. The glossiness of the surface of the ink receiving layer at this time was 32%. A polyethylene terephthalate film with a thickness of 50 μm was placed on the surface of this product, which was heat-treated under pressure with a mirror-finished metal roll with a surface temperature of 100 ° C., and the polyethylene terephthalate film was peeled off. %, A card formed with a high-quality print having excellent scratch resistance was obtained.
