<p><P>PROBLEM TO BE SOLVED: To provide a copy protection laminated material which can be printed by a laser printer or the like, excels in visibility of characters and patterns of printed original and makes the contents of the original unreadable even when the original is copied, particularly by photo mode setting, smallest-density setting or the like. <P>SOLUTION: The copy protection laminated material is composed by providing a polarized ink layer 20 and an output data layer 30 sequentially on a base 10 having a specular layer on the surface. The polarized ink layer is made of violet polarized ink which contains a colored pigment dispersed to have an average particle diameter of 1μm or less and is prepared by mixing red polarized ink having absorption between wavelengths 460 nm and 570 nm and blue polarized ink having absorption between wavelengths 500 nm and 640 nm. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
