Abstract
PURPOSE:To prohibit duplication by light transmission type copying and to effectively prevent the infringement of a portrait right, copyright, etc., by specifying the ratio between the light transmittance in the printed part of a base sheet surface and the light transmittance in the non-printed part thereof. CONSTITUTION:A manufacturer's name, merchandise name, etc., are printed on the rear face of the base sheet 2 on the front face of which a photosensitive material layer 3 is formed. The ratio of the light transmittance in the printed part 4 on the base sheet 2 surface and the light transmittance in the non-printed region 5 thereof is specified to <=0.8. The printing of the manufacturer's name, merchandise name, etc., on the rear face of this photographic paper 1 is projected on the copied image plane if the image printed on the paper 1 surface as a base is subjected to light transmission type copying. Duplication merchandising by the light transmission type copying is thus impossible. The infringement of the portrait light and copyright is thereby effectively prevented.
