ABSTRACT:
A thermally developable light-sensitive element comprising a support having in one or more layers thereon at least (a0) an organic silver salt, (b) light-sensitive silver halide grains and (c) a reducing agent, wherein the average grain size of the light-sensitive silver halide grains is not less than about 0.05 .mu. and the support is gas permeable and, in addition, carries thereon a subbing layer composed of at least one copolymer selected from the group consisting of a vinyl chloride type copolymer in which vinyl chloride is present in the copolymer in an amount of about 50 molar % or higher and a vinylidene chloride type copolymer in which vinylidine chloride is present in the copolymer in an amount of about 50 molar % or higher. The thermally-developable light-sensitive element of the invention is highly sensitive and in addition, has a good storage stability retaining on storage the properties possessed by the "fresh" photosensitive element even under high humidity and/or high temperature conditions.
