PURPOSE:To prevent the infringement of a portrait right, etc. by forming a color of saturation C*10 or above of a Munsell system on the rear face of a base sheet on the front face of which a photosensitive material layer is formed. CONSTITUTION:The color of the saturation C*10 or above in Munsell system is formed on the rear face of the base sheet 2 on the front face of which the photosensitive material layer 4 is formed. The transmission of the wavelength light having the relation of complementary color with the color on the rear face of the base sheet 2 is hindered if the image printed on this photographic paper is subjected to light transmission type copying. The color balance of the copied image is, therefore, borken and only the image having poor color reproducibility is obtd. The reproduction by the light transmission type copying is thereby made valuless as merchandise quality and the infringement of the portrait right, etc., is averted. |
