Abstract

Abstract A process for forming photographic image is disclosed, comprising photographically developing, in the presence of a polyalkylene oxide compound, a silver halide photographic light-sensitive material including at least one silver halide emulsion layer and containing in at least said emulsion layer or other hydrophilic layer a compound represented by formula (I). ##STR1## wherein: A and A' each represents a hydrogen atom or an alkalihydrolyzable group; R 1 , R 2 , and R 3 each represents a group capable of substituting a hydrogen atom on the hydroquinone nucleus, with R 2 and R 3 , A and R 1 , or A and R 2 together form a ring; and X represents a group which shows a development-inhibiting effect after being released.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 162 words
A process for forming a photographic image, comprising: (1) imagewise exposing a silver halide photographic light-sensitive material including at least one silver halide emulsion layer and containing in at least said emulsion layer or other hydrophilic layer a compound represented by formula (I) ##STR7## wherein: A and A' each represents a hydrogen atom or an alkalihydrolyzable group; R 1 , R 2 , and R 3 each represents a hydrogen atom or group capable of substituting a hydrogen atom on the hydroquinone nucleus, or R 2 and R 3 , A and R 1 , or A and R 2 together form a ring, wherein said ring is a 5-6 membered ring; and X represents a group which shows a development-inhibiting effect after being released, and (2) photographically developing the resulting imagewise exposed silver halide photographic light-sensitive material, using a lithographic developer, wherein a polyalkylene oxide compound is employed in said silver halide photographic light-sensitive material, or said lithographic developer or both.
Claim 2
Dependent Claim 162 words
A process for forming a photographic image, comprising: (1) imagewise exposing a silver halide photographic light-sensitive material including at least one silver halide emulsion layer and containing in at least said emulsion layer or other hydrophilic layer a compound represented by formula (I) ##STR7## wherein: A and A' each represents a hydrogen atom or an alkalihydrolyzable group; R 1 , R 2 , and R 3 each represents a hydrogen atom or group capable of substituting a hydrogen atom on the hydroquinone nucleus, or R 2 and R 3 , A and R 1 , or A and R 2 together form a ring, wherein said ring is a 5-6 membered ring; and X represents a group which shows a development-inhibiting effect after being released, and (2) photographically developing the resulting imagewise exposed silver halide photographic light-sensitive material, using a lithographic developer, wherein a polyalkylene oxide compound is employed in said silver halide photographic light-sensitive material, or said lithographic developer or both.
Claim 3
Dependent Claim 187 words
A process for forming a photographic image as in claim 1, wherein A and A' each represents a member selected from a hydrogen atom, a substituted or unsubstituted acyl group, an alkoxycarbonyl group, and an aryloxycarbonyl group; R 1 , R 2 , and R 3 each represents a member selected from a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a halogen atom, a hydroxy group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted acyl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted amido group, a substituted or unsubstituted sulfonamido group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted sulfonyl group, and a heterocyclic ring group, a group represented by X, or R 2 and R 3 , A and A 1 , A and R 2 or A' and R 3 together form a ring, X representing a group which shows a development inhibiting effect after being released.
Claim 4
Dependent Claim 43 words
