Abstract

Abstract A photographic material which comprises a light-­sensitive silver halide emulsion layer and a non-light-­sensitive hydrophilic colloid layer provided outside of the light-sensitive silver halide emulsion layer to the supportis disclosed. Total content of gelatin of the layers at a side of the silver halide emulsion layer is 2.0 to 2.8 g/m² and the non-light-sensitive hydrophilic colloid layer contains a polymer latex. The material provides a high contrast image and is suitable for the use of lithography.
