Method for producing special latent image pattern forming body and special latent image pattern forming body

摘要

To provide a special latent image pattern-formed body capable of expressing a latent image pattern as a continuous gradation image when observing a base material under transmitted light, without requiring a special authenticity check tool.SOLUTION: The present invention relates to a special latent image pattern-formed body formed by laminating a latent image layer comprising a positive picture and a negative picture which form latent images, a concealing layer concealing the latent image layer under reflected light and a camouflage layer comprising camouflage lines having the same density as the latent image lines, on a light-transmissible substrate. Since the camouflage lines hide a part of negative images when the special latent image pattern-formed body is observed under transmitted light, latent images comprising positive images appear.SELECTED DRAWING: Figure 1
