Example

The surface of the metal plate was subjected to a step of CNC machining or laser machining to produce a copper plate on which the fine uneven patterns 11 were formed.

The concavo-convex pattern 11 produced in the above step is fabricated so that it can feel the unique texture of the metal and feel high-quality.

In some cases, it is possible to use an etching processing method of developing a picture or a letter on a metal plate by a film and corroding it by a chemical method, and the etching processing can form a fine picture or character while precisely forming a metal- It is possible.

Next, as shown in Figs. 2A and 3A and 3B, a synthetic resin sheet is placed on the copper plate 10, and the convex-concave pattern 11 of the copper plate 10 is transferred to the synthetic resin sheet by heating and pressing, A step of completing the printing sheet 21 was carried out.

Subsequently, as shown in Figs. 2B and 3C, the upper printed sheet 21 to which the uneven pattern 21a is transferred is placed in the vacuum chamber 30, and the metal compound 32 placed on the target 31 As shown in FIG. 3D, the surface of the metal compound 32 is heated with accelerating electrons by irradiating an electron beam (E-beam) to vaporize the surface of the metal compound 32 to form a metal thin film 21b on the surface of the upper printed sheet 21 The deposition step was performed.

The metal compound 32 used in the above step is a compound containing tin (Sn) as a main component and is irradiated with an electron beam (E-beam) by an electron beam generator to heat the surface of the tin by accelerating electrons. A metal material vaporized by surface heating is deposited on the surface of the upper printed sheet 21 to form the metal thin film 21b.

When the metal thin film 21b is coated on the surface of the upper printed sheet 21 by the primary deposition step, the metallic color that can feel high quality by emitting a high gloss can be displayed. The irregular pattern 21a is made of metal It is possible to reproduce the texture pattern of the metal plate to give a feeling of processing.

Subsequently, the fluorine resin compound placed on the target 31 is irradiated with an electron beam to vaporize the surface while heating the surface to form an AF (Anti-Finger) water-repellent coating layer 21 on the surface of the upper printed sheet 21, And a second deposition step of forming the first electrode 21c.

The water-repellent coating layer 21c formed by the above step allows the upper printed sheet 21 to be completely waterproofed and smoothly coated so as to prevent foreign substances such as dust from adhering due to no fingerprints remaining even when the user touches the upper printed sheet 21 The durability of the entire upper-printing sheet 21 can be improved, and the luster of the metal can be expressed well.

Next, as shown in Figs. 2C and 3F, a core sheet 22 made of synthetic resin and a lower printed sheet 23 are sequentially laminated on the lower part of the upper printed sheet 21 after the first and second deposition operations have been completed, Followed by laminating by heating and pressing.

Next, as shown in FIGS. 2d and 3g, the steps of cooling the heat-sealed sheets and cutting the card according to the outline of the card were completed, thereby completing the fabrication of the plastic card in which the metal vapor deposition was completed.

As shown in FIG. 3H, the vacuum deposition plastic card 20 may further include a step of attaching the IC chip 24 by machining a guide groove with a milling cutter such as CNC to store a large amount of information And a step of attaching a magnetic tape 25 to the bottom surface of the lower printed sheet 23 so that various kinds of information can be recorded on the magnetic tape 25 It can be used as a recorded card.

The vacuum deposited plastic card 20 completed by the above-described manufacturing process can be obtained by a process wherein the uneven pattern 11 of the copper plate 10 is transferred to the synthetic resin sheet to form precise patterns and patterns, Since the upper printed sheet 21 is made of synthetic resin, it is possible to reproduce a pattern unique to metal that can feel the texture. Even if the upper printed sheet 21 is made of synthetic resin, it is possible to produce a high quality vacuum- It can be implemented.

The concavo-convex pattern 21a of the upper printed sheet 21 to which the pattern of the copper plate 10 is transferred is more stereoscopic and exhibits a metal-specific texture while the water repellent coating layer 21c by the two- Therefore, the metal thin film is not peeled off and the dust does not stick even if it is used for a long period of time, so that the durability of the entire plastic card 20 is enhanced. I can give.

On the other hand, the vacuum-deposited plastic card 20 completed by the above-mentioned manufacturing process has the following advantages. The concave-convex pattern 11 of the copper plate 10 is transferred to the upper printing sheet 21 and the metal thin film 21b is formed on the surface of the upper printing sheet 21 by the first vacuum vapor deposition, A water repellent coating layer 21c is formed on the surface of the metal thin film 21b and a core sheet 22 and a lower printed sheet 23 made of synthetic resin are laminated and laminated on the lower part of the upper printed sheet 21, As shown in FIG.
