摘要
PROBLEM TO BE SOLVED: To solve problems such as the shortage of the durability of latent image patterns due to printing under a condition that an angle of parallel lines are varied and the realization of the state being easily attracted attention and easily being analyzed when specular layers are made of parallel lines in a laminating structure with the specular layers. SOLUTION: An image displaying body 5 on a base material has a light diffracting structure as its back ground and hidden patterns 3a to 3d made of parallel lines having slant angles different from one another. In addition, by piling up a confirming sheet 7 having parallel lines interfering with the parallel lines of hidden patterns to respective hidden pattern by varying its slant angle, the respective hidden pattern can be constituted to be developable.
