Abstract
A method for forming an image comprising forming a silver, silver halide or binder image in the emulsion layer of a photographic material which comprises a support having a masking layer thereon which carries a silver halide emulsion layer, by exposing and developing the photographic material, heating the photograpic material to thermally decompose the binder of the emulsion layer, selectively removing the thermally decomposed emulsion layer at non-image areas to uncover the masking layer lying thereunder using a binder-removing solution, and then etching away the masking layer at the uncovered areas.
