Abstract
Abstract This invention relates to a development inhibitor-releasing compound of the following general formula: ##SPC1## Wherein Z is an atomic grouping necessary to form a carbocyclic ring; Y is a group which, when the sulfur atom of the thioether linkage is released, forms together with said sulfur atom a compound having a development-inhibiting action; and X is a hydroxyl group or a substituted or non-substituted amino group.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A process for developing an imagewise exposed, light-sensitive silver halide photographic material which comprises developing the photographic material in the presence of a compound having the general formula: ##SPC4## wherein Z is an atomic grouping necessary to form a 5, 6 or 7 membered carbocyclic ring; Y is a group which, when the sulfur atom of the thioether linkage is released, forms together with said sulfur atom a compound having a development-inhibiting action; and X is a hydroxyl group or a substituted or nonsubstituted amino group.
Claim 2
Dependent Claim
86 words
A process for developing an imagewise exposed, light-sensitive silver halide photographic material which comprises developing the photographic material in the presence of a compound having the general formula: ##SPC4## wherein Z is an atomic grouping necessary to form a 5, 6 or 7 membered carbocyclic ring; Y is a group which, when the sulfur atom of the thioether linkage is released, forms together with said sulfur atom a compound having a development-inhibiting action; and X is a hydroxyl group or a substituted or nonsubstituted amino group.
