Abstract
Abstract A photographic light-sensitive material comprising a support having thereon at least one silver halide photographic emulsion layer and at least one of the layers of the photographic light-sensitive material containing a compound represented by the following general formula (I) or (II); ##EQU1## wherein R 1 , R 2 and R 3 each represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic residue, or R 1 and R 2 can combine to form a ring; and Z represents an alkylene group; or an organic acid salt or a mineral acid salt of the compound represented by the general formula (I) or (II). The photographic material can be developed at an elevated temperature without fog information and a decrease in photographic sensitivity.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A photographic light-sensitive material comprising a support having thereon at least one silver halide photographic emulsion layer at least one of the layers of the photographic light-sensitive material containing in an amount sufficient to inhibit fog, a compound of the following general formulae (I) or (II): ##EQU3## wherein R 1 , R 2 and R 3 each represents a hydrogen atom, an alkyl group, an aryl group or a six member heterocyclic ring containing up to two nitrogen atoms with the remaining atoms of the six member ring being carbon atoms, or R 1 and R 2 can combine to form a ring through a dimethylene group or a methylene carbonyl group in which the methylene moiety can be substitued with an alkyl group having 1 to 4 carbon atoms or a phenyl group, and Z represents an alkylene group having 2 to 4 carbon atoms or the organic acid salts or mineral acid salts of the compound of the general formula (I) or (II).
Claim 2
Dependent Claim
165 words
A photographic light-sensitive material comprising a support having thereon at least one silver halide photographic emulsion layer at least one of the layers of the photographic light-sensitive material containing in an amount sufficient to inhibit fog, a compound of the following general formulae (I) or (II): ##EQU3## wherein R 1 , R 2 and R 3 each represents a hydrogen atom, an alkyl group, an aryl group or a six member heterocyclic ring containing up to two nitrogen atoms with the remaining atoms of the six member ring being carbon atoms, or R 1 and R 2 can combine to form a ring through a dimethylene group or a methylene carbonyl group in which the methylene moiety can be substitued with an alkyl group having 1 to 4 carbon atoms or a phenyl group, and Z represents an alkylene group having 2 to 4 carbon atoms or the organic acid salts or mineral acid salts of the compound of the general formula (I) or (II).
