<P>PROBLEM TO BE SOLVED: To provide a printed article whose colorful latent image is capable of being visually recognized when the angle of observation is made different by using a precise dot constitution to a light brilliant base material, and whose different latent images under an IR ray light source are capable of being visually recognized. <P>SOLUTION: The printed article is produced by laminating a second layer comprising an opacifying material for suppressing light brilliant properties on a first layer comprising a light brilliant material, and furthermore forming a third layer thereon by use of a first region with a chromatic coloring material, a second regions arranged at least two regions surrounding the first region and with different chromatic coloring materials and dots of a third region having an IR absorbing coloring element, and being made to have a visible image of a continuous gradation, a first latent image of a full color visually recognized by making the angle of the observation different, and a second latent image visually recognized under an IR ray light source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
