<P>PROBLEM TO BE SOLVED: To provide a support which can form two different latent image picture by making a fusion of a projecting image defining line of a base material itself and a printed image defining line by colored ink. <P>SOLUTION: This forgery-proof support includes a first image defining line group composed of a plurality of arranged first projecting image defining lines, formed on the base material itself, and a second image defining line group composed of a plurality of second image defining lines formed in different color printing inks from the color of the base material, arranged on the first image defining lines. In addition, the first image defining line group includes a plurality of first image defining lines with a first notched part formed on one of the projecting slopes and a second notched part formed on the other slope. Meanwhile, the second image defining line group is arranged straddling on both slopes of the first image defining line, and also, includes a plurality of second image defining lines with a first latent image part and a second latent image part to which a printing ink is not applied, arranged in the same position as each notched part. Besides, two latent image pictures are formed which can be recognized at different observation angles by virtue of each notched part and also each latent image part arranged plurally. <P>COPYRIGHT: (C)2013,JPO&INPIT |
