である。
Conventionally, attempts have been made to apply materials such as silver halide photography, diazo photography, and free radical photography as optical recording materials in order to record arbitrary information on cards. After arbitrary information is recorded using such a recording material, it is usually covered with a transparent plastic film, which serves not only for mere protection but also for prevention of forgery. Preventing counterfeiting is particularly important for ID cards such as bank cash cards, identification cards, credit cards, and introductory cards for checking access to sensitive areas.

However, the above-mentioned conventional cards require development processing, and the complexity of covering them with a transparent plastic film after development is unavoidable.
Furthermore, if the card is covered with a transparent plastic film before recording, it becomes difficult to record and develop the card, and furthermore, once arbitrary information has been recorded on the card, it is extremely troublesome and impossible to remove the transparent plastic film on the surface of the card. Therefore, the prevention of counterfeiting is not perfect, and other disadvantages cannot be avoided.

As a result of examining various materials to solve the above problems, the inventor of the present invention discovered that even if the laser recording material is coated with a transparent plastic film etc. in advance, the functional performance will not be impaired, and furthermore, in an attempt to counterfeit it. They discovered that if they tried to remove the plastic film, the recording layer itself would be damaged, making counterfeiting impossible.
The present invention is characterized in that a low melting point metal thin film layer with a thickness of 100 to 1000 Å is provided on the surface of the card base material, and a transparent synthetic resin protective layer with a thickness of 10 to 2000 μm is further laminated on the surface of the metal thin film layer.

The card of this invention has a thickness of 100 to 1000 on the surface of the base material.
A low melting point metal thin film layer with a thickness of 100 μm is provided, and a transparent synthetic resin protective layer with a thickness of 10 to 2000 μm is laminated on the surface of the low melting point metal thin film layer. Even if it is coated with a protective layer, its functional performance will not be impaired, and if an attempt is made to forgery and the transparent synthetic resin protective layer is removed, the low melting point metal thin film layer itself, which is the recording layer, will be damaged.
Impossible to counterfeit. In addition, since the thickness of the low melting point metal thin film layer is limited to 100 to 1000 Å, it is easy to read after laser recording, and furthermore, the thickness of the transparent synthetic resin protective layer is limited to 10 to 2000 μm, so transparent synthetic resin Laser recording from above the resin protective layer can be made possible.

使用しうる。 Any card base material may be used as long as it has rigidity and is suitable for processing such as heat fusion and various types of printing, but usually vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, chloride resin, etc. Vinylidene resin, acrylic resin, styrene resin, vinyl butyral resin, acetyl cellulose resin, styrene
Synthetic resins such as butadiene copolymer resin, polyethylene resin, and fluororesin can be used, and among them, vinyl chloride resin is used because of its ease of processing. In addition, paper, metal foil, etc., and composites of the above materials may also be used.
以上のカード基材に低融点金属薄膜層を設け

の公知の方法により行える。 The metals constituting the low melting point metal thin film layer include:
Te, Bi, In, Sn, Zn, Pb, Ge, Ga, Rh, Al, etc. can be used, and among them, low melting point metals such as Te, Bi, Sn, and In can be used for recording even if the energy density required for recording is low. It's good to be able to do it. Note that the above metals may be used alone or in combination of two or more. A low melting point metal thin film layer using the above metals can be formed by known methods such as vacuum evaporation, sputtering, ion plating, plasma evaporation, electroplating, and electroless plating.

なマスクを用いるとよい。 The thickness of the low melting point metal thin film layer is 100 to 1000 Å, preferably 200 to 500 Å. In the above, below 100 Å, the difference in optical density between the recorded area and the unrecorded area due to laser beam irradiation becomes extremely small, making it difficult to read, and when it exceeds 1000 Å, the recording energy threshold also becomes high and the pit shape of the recorded area changes. This is not desirable as it becomes difficult to read. Incidentally, when providing the low melting point metal thin film layer as described above, if it is desired to provide it only on a desired portion of the card base material, an appropriate mask may be used.
次に、低融点金属薄膜層の上に透明合成樹脂保

m, preferably 200 to 1500 μm. If the thickness is less than 10 μm, the strength as a protective layer is insufficient, and
If it exceeds 2000 μm, it becomes difficult for the laser beam to reach the low melting point metal thin film layer, which is not preferable. In addition, especially in the range of 1000 to 1500 μm, there is an effect of avoiding interference with the laser light due to fingerprints, dust, etc. attached to the surface of the transparent synthetic resin protective film.

Kg／cm2である。 In the present invention, the transparent synthetic resin protective layer focuses on protecting the low melting point metal thin film layer and laser recording from above the transparent synthetic resin protective layer, so it is sufficient to cover only the surface of the low melting point metal thin film layer. Since it is provided on the entire surface, it may be provided on the entire surface in the present invention as well. The transparent synthetic resin protective layer can be provided by applying, printing and drying using a known transparent synthetic resin paint, or by gluing or heat-sealing a transparent synthetic resin film or a transparent synthetic resin plate. As the transparent synthetic resin film or plate, the synthetic resin film or sheet described above as the card base material can be used, and the heat fusion conditions are 100 to 300°C, 40 to 400°C.
