トしたいわゆるシーピーリーフが知られている。``Prior Art and Problems to be Solved by the Invention'' Conventionally, a so-called CP leaf is known, which is a plastic card base plate laminated with a plastic laminate film on which required information such as letters and photographs are printed.
しかしながら、このようなシーピーリーフは比較的簡単

ある。However, there is a problem in that such a CPP leaf can be counterfeited relatively easily, and its authenticity cannot be easily confirmed.

とが可能である。By the way, it is generally known that characters or patterns are printed on the surface of an object using fluorescent paint that emits light in various colors when exposed to ultraviolet rays, and then irradiated with short-wavelength ultraviolet rays using an ultraviolet irradiator to display luminescence. However, since the fluorescent paint is printed on the front side, the fluorescent paint is easily peeled off, and furthermore, it is possible to easily print the fluorescent paint from the front side.

ある。As a result of various research and experiments conducted to solve the above-mentioned conventional problems, this invention is based on printing ultraviolet fluorescent paint on the back side of a transparent plastic film and transmitting the film from the front side. They discovered that when irradiated with ultraviolet rays, short wavelength ultraviolet rays hardly emit light, but long wavelength ultraviolet rays emit light. By printing a luminescent identification label and laminating the back side of the label onto a plastic card base, the luminescent identification label cannot be manipulated, and moreover, the luminescent identification label can be made to emit light by irradiation with short wavelength ultraviolet rays without peeling off. This paper proposes a light-emitting identification card for preventing counterfeiting that can reliably determine authenticity without being counterfeited.
「実施例」以下この発明を図面に示す実施例について説明すると、
この発明の偽造防止用発光識別カードはプラスチック製

The anti-counterfeit luminescent identification card of the present invention is manufactured by closely laminating a transparent plastic laminate film 2 onto a plastic card base plate 1.

ている。The laminate film 2 is a transparent plastic film made of vinyl chloride, polyester, polypropylene, polycarbonate, polyethylene, etc., and has an adhesive back surface or is a hot melt film,
Required information such as letters, symbols, photographs, or patterns necessary for the card are printed on the back side of the card, and a luminescent identification mark 3 is printed with ultraviolet fluorescent paint at the required location on the back side.On the back side, the card base plate 1 It is laminated by dry lamination method or exclusion extrusion method.

っている。The ultraviolet paint printed on the back side of the transparent laminate film 2 (between the card base l and the film 2) is a long wavelength (for example, 366 NW) that is irradiated from the front side of the laminate film 2 by an ultraviolet irradiator and transmitted. It emits light under ultraviolet rays of 254 NW, but hardly emits light under ultraviolet rays of short wavelength (for example, 254 NW).It is usually white, so if the card base 1 is white, it cannot be identified by sunlight or ordinary lighting. Marker a3 is almost impossible to identify.

本物のカードであるか否かが容易に判別できる。"Operation of the invention" When the front side of the luminescent identification card is irradiated with long-wavelength ultraviolet rays from an ultraviolet irradiator, the luminescent identification mark 3 emits various colors of light through the laminate film 2, and short-wavelength ultraviolet rays are irradiated. Since these cards hardly emit any light, it is easy to tell whether the card is a genuine card or not.

るため、偽造であることが識別できることになる。Even if a similar luminescent identification mark 3 is forgedly printed on the surface of the laminated film of the card, it will not emit light when irradiated with long-wavelength ultraviolet rays, but on the contrary, it will emit light when irradiated with short-wavelength ultraviolet rays, so it will be considered a forgery. can be identified.

造細工も不可能となる。In addition, a product with the luminescent identification mark 3 printed on the front side is not durable because it can be easily peeled off by rubbing it with a hard object, but a product with the luminescent identification mark 3 printed on the back side as in this invention is not durable. It cannot be removed, is durable, and cannot be counterfeited.

て確実にカードの真偽を判別することが可能となる。"Effects of the Invention" As described above, according to the present invention, the back surface of a transparent plastic film made of vinyl chloride polyester, polypropylene, polycarbonate, polyethylene, etc. is adhesive or the back surface of a hot melt laminate film is coated with fluorescent paint. By printing a luminescent identification mark and laminating it on a plastic card base on the back side, the luminescent identification mark cannot be counterfeited and can maintain its durability without being peeled off. By irradiating long-wavelength ultraviolet rays through a laminated film, the luminescent identification mark emits light.Since short-wavelength ultraviolet light hardly emits light, it is possible to clearly distinguish it from counterfeit products and reliably determine the authenticity of the card. becomes possible.
