Abstract

Heat developable light-sensitive photographic material having a layer which contains a light-sensitive combination of a silver compound substantially insensitive to light, a reducing agent for that silver compound and a polymethine sensitizer. The exposed material is heated so that the silver compound in the exposed areas is reduced and a visible silver image is formed.
