Silver halide photosensitive material

Claim 1

A silver halide photosensitive material comprising two or more monodisperse silver halide emulsions of different average grain size on a support, wherein at least one of said monodisperse silver halide emulsions has an average grain size of at least 0.7 μm, and at least one of the silver halide emulsions has a smaller average grain size than the other, the average grain size of the silver halide emulsion as a whole being within the range of from 0.33 to 0.54 μm, with a coated silver weight of from 2.3 to 3.8 g/m 2 , and which contains a sensitizing dye represented by formula (I) ##STR9## wherein Z and Z 1 each represents a group of non-metallic atoms forming a thiazole nucleus, a benzothiazole nucleus, or a benzoxazole nucleus; R 0 represents an alkyl group having from 1 to 6 carbon atoms, an allyl group, or an aralkyl group; R and R 1 each represents an alkyl group or an aryl group; L, L 1 , and L 2 each represents a methine group; X represents an anion; and m represents 0 or 1, and an internal salt is formed when m is 0.

Claim 12

A method for processing a silver halide photosensitive material in an automatic processor with a procedure which includes at least development, fixing, water washing or stabilization and drying, said silver halide photosensitive material being a silver halide photosensitive material comprising two or more monodisperse silver halide emulsions of different average grain size on a support, wherein at least one of said monodisperse silver halide emulsions has an average grain size of at least 0.7 μm, and at least one of the silver halide emulsions has a smaller average grain size than the other, the average grain size of the silver halide emulsion as a whole being within the range of from 0.33 to 0.54 μm, with a coated silver weight of from 2.3 to 3.8 g/m 2 , and which contains a sensitizing dye represented by formula (I) ##STR10## wherein Z and Z 1 each represents a group of non-metallic atoms forming a thiazole nucleus, a benzothiazole nucleus, or a benzoxazole nucleus; R 0 represents an alkyl group having from 1 to 6 carbon atoms, an allyl group, or an aralkyl group; R and R 1 each represents an alkyl group or an aryl group; L, L 1 , and L 2 each represents a methine group; X represents an anion; and m represents 0 or 1, and an internal salt is formed when m is 0, wherein the whole process from the development through to the drying is completed within 75 seconds.

Claim 13

A method for processing a silver halide photosensitive material in an automatic processor with a procedure which includes at least development, fixing, water washing or stabilization and drying, said silver halide photosensitive material being a silver halide photosensitive material comprising two or more monodisperse silver halide emulsions of different average grain size on a support, wherein at least one of said monodisperse silver halide emulsions has an average grain size of at least 0.7 μm, and at least one of the silver halide emulsions has a smaller average grain size than the other, the average grain size of the silver halide emulsion as a whole being within the range of from 0.33 to 0.54 μm, with a coated silver weight of from 2.3 to 3.8 g/m 2 , and which contains a sensitizing dye represented by formula (I) ##STR10## wherein Z and Z 1 each represents a group of non-metallic atoms forming a thiazole nucleus, a benzothiazole nucleus, or a benzoxazole nucleus; R 0 represents an alkyl group having from 1 to 6 carbon atoms, an allyl group, or an aralkyl group; R and R 1 each represents an alkyl group or an aryl group; L, L 1 , and L 2 each represents a methine group; X represents an anion; and m represents 0 or 1, and an internal salt is formed when m is 0, wherein the whole process from the development through to the drying is completed within 75 seconds.
