<P>PROBLEM TO BE SOLVED: To provide a printed matter having a latent image which is applied to a bank note, a passport, securities, a commodity tag, various kinds of certificates or the like for preventing forgery and duplication. <P>SOLUTION: A concealment layer for suppressing the transmittance of a base material is laminated on the base material composed of a transmissive material and further an image forming layer is formed by using a first element which is formed of a color material, a second element which has a hollow part or a color material of high transmittance and a third element which has an infrared ray absorption dye so as to form an image line-like shape. An image is formed by making widths of respective elements in the image forming layer partly different from one another. Thus the printed matter has a visible image by the first element, a first latent image by the second element which can be visually recognized when the base material is recognized under transmitted light and a second latent image by the third element which can be visually recognized when recognized under an infrared light source. <P>COPYRIGHT: (C)2012,JPO&INPIT |
