<P>PROBLEM TO BE SOLVED: To provide a latent image patterned form with improved visibility of a design viewed from the front, in which even when being formed of multiple colors, there is no limit in the arrangement of the design observed from the front and the design of a latent image pattern observed obliquely, and in which visibility of a latent image does not deteriorate. <P>SOLUTION: On a base material, a plurality of first elements having recessed or projecting shapes are arranged in a line pattern to form an irregular pattern, a plurality of second elements having a color different from that of the first elements are arranged in a line pattern to form a second pattern, and a plurality of third elements having a color the same as or different from the second elements are arranged in a line pattern to form a third pattern. The second elements and the third elements are formed as one set with the position where the density is partially different being the same with each other. A visible image is formed by the difference in density of the plurality of sets. The second elements are overlapped on one of a latent element and a background element that are divided in which the phases of the first elements are partially different, and the third elements are overlapped on the other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
