<p><P>PROBLEM TO BE SOLVED: To provide a printed article capable of visually recognizing a colorful latent image under transparent light, and visually recognizing different latent images under an IR light source by using a precise dot constitution to a transparent base material. <P>SOLUTION: The printed article is produced by laminating an opacifying layer comprising an opacifying material for suppressing transparent properties on a base material comprising a light transparent material, and furthermore forming an image-forming layer thereon by use of a first region based on a colored coloring material, a second region divided into at least two color divided regions by different colored coloring materials different from each other, and dots in a third region having an IR absorbing coloring element to thereby have a visible image with a continuous gradation, a first full color latent image visually recognized under transparent light and a second visually recognizable latent image under an IR ray light source. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
