せてもよい。 Note that when the card base material is paper or synthetic resin, even if the light reflectance is high on the outside, it is usually lower than the light reflectance of the optical recording layer.
Information can be reproduced. However, in order to improve the S/N ratio during playback, or when using a base material with a metal mirror surface on its surface, it is recommended to first laminate a low-reflection layer with low light reflectance on the surface of the base material. Providing an ink layer with high optical reflection density (that is, low light reflectance) on the surface of the card base material,
A low-reflection layer is formed by depositing non-reflection chromium or bonding a colored synthetic resin film. Of course, the above-mentioned low-reflection layer may be formed between the optical recording layer and the adhesive layer of the optical recording layer transfer sheet of the present invention, and in this case, the optical recording layer and the low-reflection layer may be formed as necessary. An adhesive layer may be interposed between them.
