<p><P>PROBLEM TO BE SOLVED: To provide a color and image changeable imaging element wherein the first image lines are printed on a substrate, and a transparent material layer is formed thereon by using a screen printing and a laminate processing, and furthermore, the second image lines and the third image lines capable of covering the first image lines are printed thereon, and as the first image lines can be selectively observed from a part being not covered with the second and third image lines, it can be realized before only by performing a front-to-back printing on a transparent card substrate, but the color and the image change with changing the angle of observation even on an opaque substrate such as a paper. <P>SOLUTION: The imaging element is forming a plurality of the first image lines 2 with n colors (n is an integer) different from the color of the substrate on a part or the whole of the substrate, a layer with a specified thickness with a transparent or semi-transparent material on the first image lines and non-image line, and a plurality of the second and the third image lines 4 on the layer, forming a message of the second image lines, and forming a background of the third image lines. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
