Various attempts have been made using processing means, functional materials such as magnetic materials, conductive materials, photosensitive materials, heat-sensitive materials, foamed materials, and luminescent materials, and detection means according to the functions, either alone or in combination.

という欠点があった。Among these functional materials, methods of reading information using substances that selectively absorb light of specific wavelengths are already known, and in particular, methods using near-infrared absorbers or ultraviolet absorbers are difficult to record hidden information. Various methods have been proposed because they are easy to perform. For example, a method of printing securities using a thermal transfer ink sheet containing a near-infrared absorbing material (Japanese Patent Application Laid-Open No.
-14658) exemplifies a printed matter that is extremely pale in color and difficult to distinguish with the naked eye, but it has the drawback of poor light resistance.

It was inappropriate for Furthermore, a method (Japanese Patent Application Laid-Open No. 61-228994) has been proposed in which authenticity is determined based on the luminescence when a black light is irradiated to a recorded matter obtained using a thermal transfer recording medium containing a fluorescent substance in the ink layer. However, since the presence or absence of light emission is determined visually, it has the disadvantage that the identification cannot be automated.

Both compounds have the advantage of being excellent in light resistance. Among these exemplified ultraviolet absorbers or blocking agents, those that are visible because they are colored can be made visually difficult to distinguish depending on the relationship with the background of the transfer object. Furthermore, if necessary, a layer that causes cohesive failure during transfer can be provided between the base material and a heat-melting ink layer containing an ultraviolet absorber and/or an ultraviolet blocker, thereby producing a recorded matter with a matte effect. You can get it.

化が容易となる。(Operations and Effects of the Invention) According to the present invention, individual information codes with excellent light resistance are printed (recorded) using a heat-sensitive transfer material provided with a heat-sensitive transfer ink that absorbs and/or blocks ultraviolet rays. Can be granted. The above-mentioned information code can be made difficult to visually identify by matching the color with the base or making the printed surface matte, so it is also effective as a means to prevent counterfeiting and number entry. Furthermore, since the recorded matter can be detected with an optical device that is sensitive to ultraviolet light, automation of identification becomes easy.
