PROBLEM TO BE SOLVED: To make an alternation impossible by removing a pattern layer as well when a dye image on a receiving layer is removed with a solvent, by laminating the receiving layer which is dye-acceptable and solvent-soluble through the pattern layer at one section of a base material to be printed, and providing an image wherein one section of the pattern layer is solvent-soluble, and the receiving layer is dyed with a dye. SOLUTION: A pattern layer 3 is laminated on a base material 2 to be printed, and a dyable layer 4 is laminated on the pattern layer 3, and both of the pattern layer 3 and the receiving layer 4 have a solvent-solubility, and the dyable layer 4 is dyable and has an image 5 comprising a dye on the upper surface and the vicinity of the dyable layer 4. In this case, as a representative printing base material 2, a polyvinyl chloride resin sheet which is a base material for articles being used for so-called cards is normally used because of the suitability for a printing and a working, and paper and a metal foil or the like are used other than the sheet. Also, the pattern layer 3 is constituted in such a manner that at least one section of the pattern layer 3 may be dissolved and collapse together with the dyable layer 4 when the image 5 is tried to be removed by making a solvent react with the receiving layer 4 having the image 5. |
