<p>PROBLEM TO BE SOLVED: To provide an anti-counterfeit formed body bestowed with latent images appearing under different observing conditions of the variation of an observing angle and the superimposition of a discriminator, and a preparation method for the same.SOLUTION: The provided anti-counterfeit formed body is formed by arranging, atop a substrate, a first latent image and a second latent image in an overlapping manner. The first latent image possesses: a pattern portion wherein a plurality of bulging first image lines is arranged along a first direction; a background portion wherein a plurality of first image lines is arranged in a phase different from that of the pattern portion; and a contour portion wherein a plurality of bulging contour image lines formed at an area ratio nearly a half of that of the first image lines within a specified range and possessing blank portions within gaps thereof adjacent to the first image lines is arranged in a phase different from that of the pattern portion. The second latent image consists of a plurality of bulging second image lines arranged along the first direction, where the second image lines are positioned and laminated atop the first image lines. The second latent image is visually recognized by varying the observing angle in relation to the substrate, and the first latent image can be visually recognized as a negative image or positive image by superimposing thereon a discriminator.</p> |
