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.
Claims54
A method for forming an image comprising in sequence forming a silver image in the emulsion layer of a photographic material which comprises a transparent support having a masking layer thereon, said masking layer having thereon a silver halide emulsion layer, either directly or on at least one subbing layer on the masking layer, by exposing and developing said photographic material, heating said photographic 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 selected from the group consisting of the aqueous solutions containing sodium hypochlorite, potassium hypochlorite, sodium hypobromite, potassium hypobromite, sodium chlorite, potassium chlorite, sodium chlorate, potassium chlorate, sodium bromate and potassium bromate, and then etching away the masking layer at the uncovered areas.
A method for forming an image comprising in sequence forming a silver halide image in the emulsion layer of a photographic material which comprises a transparent support having a masking layer thereon, said masking layer having thereon a silver halide emulsion layer, either directly or on at least one subbing layer on the masking layer, by exposing and developing said photographic material and bleaching said material with a suitable bleaching solution to form said silver halide image, heating said photographic 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 thereunder using a binder-removing solution selected from the group consisting of the aqueous solutions containing sodium hypochlorite, potassium hypochlorite, sodium hypobromite, potassium hypobromite, sodium chlorite, potassium chlorite, sodium chlorate, potassium chlorate, sodium bromate and potassium bromate, and then etching away the masking layer at the uncovered areas.
