Abstract:
A heat developable photosensitive material comprising a support, a first layer containing an organic silver salt, photosensitive silver halide and a reducing agent, and a second layer which is provided on same side of the first layer and farther from the support than the first layer, whereinthe first layer is formed by coating a first coating composition containing the organic silver salt, the photosensitive silver halide, the reducing agent, polymer latex in an amount of at least 30 percent by weight of the first layer in dried state and a solvent, the solvent comprising water in an amount of at least 50 percent by weight of the solvent, and the second layer is formed by coating a second coating composition comprising a polymer latex in an amount of at least 50 percent by weight of the second layer in dried state, a thickener and a solvent, the solvent comprising water in an amount of at least 60 percent by weight of the solvent, and the second coating composition having a viscosity of from 4 to 1,000 cP at 25Â° C., and the viscosity at 5Â° C. being at least 1.5 times higher than that at 25Â° C.
