ABSTRACT:
A thermodevelopable light-sensitive material having a reduced frequency to fog formation by heat, comprising a support and at least one layer containing (a) an organic silver salt, (b) a catalytic amount of a light-sensitive silver halide or a compound capable of forming a light-sensitive silver halide by reaction with the organic silver salt (a), (c) a reducing agent (d) a binder, and (e) an N-haloacetamide. In order to increase the transparency of the thermodevelopable photographic layer of the material and the density of the image and to improve its preservability, a topcoating of polymer can be formed on the light-sensitive layer.
