<p>PURPOSE:To obtain a sheet for printing which facilitates the visual identification of falsifiction when its printed part is scraped off and new letters or numerals are added and is used appropriately for gift certificates, securities, etc. CONSTITUTION:A sheet for printing is composed of a printed image fixing layer 3 placed on the surface of a sheet substrate and a fluorescent coating layer 4 laminated on the layer 3. Information of an amount of money 8 and others is printed on the surface of the sheet to provide a gift certificate 9. When the printed numerals of an amount of money 8 in the gift certificate 9 is scraped off and new numerals are added, since the fluorescent coating layer 4 in the part scraped off is removed simultaneously, the amount of the fluorescent agent is reduced in comparison with another part to decrease the degree of fluorescence. In this way, the visual identification of the falsification can be promptly and easily performed by the comparison of the fluorescence.</p> |
