Abstract

PURPOSE:To enhance the mechanical strength, and to improve the weatherability, the heat resisting and the chemical resisting properties of the titled hologram, by mounting a protective layer composed of a heat-resisting resin on the surface of a sensitive layer. CONSTITUTION:The protective layer 2 composed of the heat-resisting resin is stuck on the surface of the sensitive layer 1 which is composed of a vinyl carbazole type polymer as a main component, and is recorded with a volume phase type hologram image, through an adhesive or a sticking agent layer 3. The sticking of the protective layer 2 to the sensitive layer 1 is carried out by coating the sensitive layer 1 on a substrate 4, and sticking the protective layer 2 on a region in which the sensitive layer does not exist on the substrate 4, with the adhesive 3, or by peeling off the sensitive layer 1 from the substrate plate, and sticking the protective layer 2 on one of the sensitive layers with the adhesive layer 3. And, said sticking is carried out by mounting the protective layer 2 on the both surfaces of the sensitive layer 1, respectively, and then, sticking the upper and the back protective layers 2 on the sensitive layer with the adhesive 3 respectively.
