Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a line relief card, and more particularly to a relief card having metallic luster.

In recent years, plastic cards have become very popular, as seen in ID cards, 111-line cards, membership cards, credit cards, etc., and whether you use the above cards as is or add a magnetic recording method to the above cards. It is used to record eight stock information and is configured to function as a magnetic card.

Recently, some cards with a metallic luster and a beautiful appearance have been proposed as an improvement on the above-mentioned cards.As for this card, a metallic luster pigment is dispersed in a plastic sheet, and one letter is patterned on the metallic lustrous sheet. A nine-card card has been proposed in which a transparent plastic sheet is laminated on the front and back of the printed material.

However, this card has the disadvantage that the printed part does not have a metallic luster, and the letters and other characters are visually limited to a flat design.

The present invention aims to eliminate the drawbacks of the above-mentioned prior art and provide a round relief card, and the present inventors have conducted extensive research to achieve the above object, and as a result, a metallic lustrous sheet surface has been developed. With an uneven pattern.

By layering a transparent plastic sheet on top of this sheet, the nine letters and other patterns emerge in three dimensions.

He discovered that it was possible to obtain a relief card with a beautiful metallic luster, and succeeded in its development, leading to the completion of the present invention.

In other words, the gist of the relief card is that it is made by laminating transparent plastic sheets on both sides of a metallic glossy plastic sheet containing the metallic luster pigment of the present invention and having an uneven pattern formed on at least one side. be.

Two embodiments of the present invention will be described below based on the WA school.

IslwA has 11 of the present invention! An exemplary relief card 1 is shown. This relief card 1 is.

Metallic luster pigment! A printing ink layer 4 is formed between two metallic glossy plastic sheets 5, S containing metallic luster, and an uneven pattern 5. S is formed, and a transparent plastic layer (1) is laminated on the outer surface to form a nine structure.

In the relief card 1 of the present invention, the materials of the metal glossy plastic sheet and the transparent plastic sheet may be different or different.

Specific examples include polyvinyl chloride, polyethylene, polypropylene, polyester, polystyrene, polycarbonate, etc., but transparent materials are preferred.

The metallic luster plastic sheet 1 is produced by heating and kneading the above synthetic resin and the metallic luster pigment 2, and then using a roll or the like to produce the metallic luster plastic sheet 11! It can be obtained in the form of a smooth sheet. Examples of the metallic luster pigment 2 include lead-based compounds, bisousium-based compounds, etc.;
Parts by weight are used. In addition, a small amount of stabilizer, lubricant, etc. can be added during heating and cross-talk as described above.

The printing ink layer 4Fi is used to form a concavo-convex pattern 5 on the outer surface of the metallic luster 7-t1 (the method for this formation will be described later), and is formed by Fulx screen printing or the like. The ink used here may have a high transparency, and may be either transparent or opaque in the above embodiments.

An uneven pattern s#i 9 characters, patterns, etc. are formed, and a round shape corresponds to the printing ink layer 4.

In manufacturing the Rely 7 card 1 of the present invention, a printing ink layer 4 is formed on one side of the metallic glossy plastic sheet.
After forming, another metallic luster plastic sheet s is laminated on the printing ink layer 4 side.

Next, two metallic glossy plastic sheets 1 are laminated together.
．． The relief card 1 can be obtained by laminating transparent glass sheets 6°6 on both sides of S and then heat-pressing them from both sides. During the above pressure bonding, the metallic luster plastic sheet 3.3 is pressed by the printing ink layer 4, and an uneven pattern S having a shape corresponding to the printing ink layer 4 is formed on the metallic lustrous plastic sheet 3.8 by protruding outward. .

Fig. 2 shows a relief card 1 which is another embodiment of the Morimoto invention.
It is shown. In this relief card 1, a printing ink layer 4 is formed on the threshold between the metallic glossy plastic sheet 3 and the transparent plastic sheet, and as in the previous embodiment, the printing ink layer 4 is formed by thermocompression bonding at the time of card production. presses the metallic luster plastic sheet 3 to form an uneven pattern 5. In this embodiment, it is necessary to use a rounded transparent ink in which the printing ink layer 4 is exposed when the printing ink layer 4 is opaque.

3rd WJK Co., Ltd. Another embodiment of the present invention, a Lely 7 card, is shown, in which the metallic luster can be further enhanced by providing a two-colored plastic sheet 1.

In this relief card 1.

Colored plastic sheet 10 (metallic gloss plastic sheet I, 8 and transparent glass sheet) on both sides! , @ are laminated on the noodles, the printing ink layer 4 is formed by e) ZIIC with the colored plastic sheet 1 and the metallic glossy plastic sheet 3, and an uneven pattern S is formed on the outer surface of the metallic glossy plastic sheet $.

Here, the material of the two-colored plastic sheet 1 may be the same as or different from that of the metallic luster plastic sheet 3, and the above-mentioned 9 synthetic resin 111r can be used.

The colored plastic sheet 7 can be colored, for example, in an achromatic color such as black or gray, or in a chromatic color by blending a pigment, and in the case of black, a black pigment such as carbon black, lamp platter, or diamond black can be used. In the case of gray, a pigment containing the above-mentioned black pigment and a white pigment such as titanium white in an appropriate ratio is used, and in the case of chromatic color, 7 tarcyani/blue, watching red, titanine yellow, etc. is used. These pigments are usually used in an amount of 0.5 to 15 parts by weight per 100 parts by weight of the synthetic resin.

By providing the colored plastic sheet 1 in this way, the iris effect can be enhanced and even better metallic luster can be obtained, but black is particularly preferred.

A relief card 1 which is another embodiment of the present invention is shown in the series 4a1. This relief card consists of 1 metallic glossy plastic sheet 3 and a transparent plastic sheet.
The setting of the IMIK printing ink layer 4 is similar to that of the embodiment shown in FIG. 9 and Rr1g3, and provides the same effect.

9 In the present invention, a case where a printing ink layer is used as a means for forming an uneven pattern on a metallic glossy plastic sheet has been described as an example, but it is also possible to form an uneven pattern using a normal press or to create a similar pattern.

It is also possible to form an uneven pattern by pasting a transparent film in the shape of a literature club.

The relief card of the present invention can be used as a magnetic card by providing an inscription layer on a transparent plastic sheet, and can also be used for identification cards, membership cards, credit cards, etc.

As explained above, the relief card of the present invention.

Contains a metallic luster pigment, has an uneven pattern formed on at least one side, and has a transparent plastic sheet laminated on both sides of a good metallic lustrous plastic sheet.
