Abstract
Abstract A thermally developable, light-sensitive material is disclosed which has at least one thermally developable, light-sensitive layer formed on a support which contains (a) a light-sensitive silver halide, (b) an organic silver salt, (c) a reducing agent and (d) a binder. Said binder contains gelatin and/or a gelatin derivative and a poly(vinyl alcohol) having a viscosity average polymerization degree of not more than 700.
