Abstract: A method for producing a photomask, by exposing and development-processing a photographic material including a transparent support having thereon a masking layer and a silver halide emulsion layer to thereby form a silver image, etch-bleaching the silver halide emulsion layer to thereby remove the silver image areas, baking the remaining non-silver image areas to thereby decompose the binder contained therein, subjecting the coated support to etching to thereby remove the masking layer located at the areas corresponding to the silver image, and removing the decomposed binder to thereby uncover the masking layer at the areas corresponding to the non-silver image areas.
