Abstract

PURPOSE:To disable duplication by copying using a light transmission system and to prevent infringement of the right of likeness and copyright by forming a transparent layer specified in thickness on a photosensitive material layer fixed to a base sheet. CONSTITUTION:The photographic printing paper 1 is obtained by forming the photosensitive material layer 3 on the surface of the base sheet 2, coating the reverse face of the sheet 2 with a resin coating 2a, and further forming a >=25mum thick protective layer 4 on the layer 3. As a result, even when the copying is carried out by the light transmission exposure system by using the image of this printing paper 1 as an original and trying to bring the side of this image into close contact with the photosensitive face of a photosensitive sheet, the close contact cannot be practically achieved by the presence of the >=25mum thick protective layer 4 between the original image and the photosensitive face of the photosensitive sheet, resulting in deteriorating the resolution of the copied image, thus permitting a sharp copied image not to be obtained by the light transmission system copying, and the infringement of the right of likeness and the copyright to be effectively prevented.
