Abstract
A heat-developable light-sensitive material is disclosed. The material comprises a paper support and provided thereon, a subbing layer containing at least two hydrophobic polymers different from each other in chemical composition, and a light-sensitive layer containing a hydrophilic binder, a light-sensitive silver halide emulsion, a dye-providing substance and a reducing agent in that order. The subbing layer is provided on the paper support by coating a solution containing the hydrophobic polymers dissolved in a solvent, at least one of said polymers being substantially insoluble in the solvent independently.
