Abstract
Abstract A silver halide color photographic material comprising a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow coupler represented by formula (I): ##STR1## wherein R 1 represents a substituted or unsubstituted tertiary alkyl or aryl group; R 2 represents a chlorine atom or an alkoxy group; R 3 represents a substituted or unsubstituted alkyl or aryl group; R 4 represents a chlorine atom when R 1 represents a tertiary alkyl group or represents a hydrogen atom or a chlorine atom when R 1 represents an aryl group, and a process for forming yellow images using the same. The material can be processed by a developer solution that contains no benzyl alcohol.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
93 words
A silver halide color photographic material comprising a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow coupler represented by formula (I): ##STR49## wherein R 1 represents a substituted or unsubstituted tertiary alkyl or aryl group; R 2 represents a chlorine atom or an alkoxy group; R 3 represents a substituted or unsubstituted alkyl or aryl group; R 4 represents a chlorine atom when R 1 represents a tertiary alkyl group or represents a hydrogen atom or a chlorine atom when R 1 represents an aryl group.
Claim 2
Dependent Claim
93 words
A silver halide color photographic material comprising a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow coupler represented by formula (I): ##STR49## wherein R 1 represents a substituted or unsubstituted tertiary alkyl or aryl group; R 2 represents a chlorine atom or an alkoxy group; R 3 represents a substituted or unsubstituted alkyl or aryl group; R 4 represents a chlorine atom when R 1 represents a tertiary alkyl group or represents a hydrogen atom or a chlorine atom when R 1 represents an aryl group.
Claim 3
Dependent Claim
123 words
The silver halide color photographic material as claimed in claim 1, wherein said yellow coupler is represented by formula (II): ##STR50## wherein R 5 represents a substituted or unsubstituted tertiary alkyl group having from 4 to 8 carbon atoms: R 6 represents an unsubstituted alkyl group or an alkyl group substituted by an alkoxy group having from 6 to 20 carbon atoms, or a group represented by formula (III), (IV) or (V): ##STR51## wherein R 7 represents an unsubstituted alkyl group or an alkyl group substituted by an alkoxy group having from 1 to 12 carbon atoms, R 8 represents a substituted alkyl group having from 1 to 8 carbon atoms; and R 2 has the same meaning as that in formula (I).
Claim 4
Dependent Claim
36 words
The silver halide color photographic material as claimed in claim 1, wherein the yellow coupler is represented by formula (VI): ##STR52## wherein R 9 is an unsubstituted alkyl group having from 6 to 16 carbon atoms.
Claim 5
Dependent Claim
35 words
The silver halide color photographic material as claimed in claim 1, wherein said coupler is employed in an amount of 2×10 -3 mol to 5×10 -1 mol per mol of silver in the emulsion layer.
Claim 6
Dependent Claim
35 words
The silver halide color photographic material as claimed in claim 4, wherein said coupler is employed in an amount of 1×10 -2 mol to 5×10 -1 mol per mol of silver in the emulsion layer.
Claim 7
Dependent Claim
114 words
A process for forming yellow images comprising developing an imagewise exposed silver halide color photographic material comprising a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow coupler represented by formula (I): ##STR53## wherein R 1 represents a substituted or unsubstituted tertiary alkyl or aryl group; R 2 represents a chlorine atom or an alkoxy group; R 3 represents a substituted or unsubstituted alkyl or aryl group; R 4 represents a chlorine atom when R 1 represents a tertiary alkyl group or represents a hydrogen atom or a chlorine atom when R 1 represents an aryl group, wherein said material is developed in the absence of benzyl alcohol.
Claim 8
Dependent Claim
114 words
A process for forming yellow images comprising developing an imagewise exposed silver halide color photographic material comprising a support having coated thereon at least one light-sensitive silver halide emulsion layer containing a yellow coupler represented by formula (I): ##STR53## wherein R 1 represents a substituted or unsubstituted tertiary alkyl or aryl group; R 2 represents a chlorine atom or an alkoxy group; R 3 represents a substituted or unsubstituted alkyl or aryl group; R 4 represents a chlorine atom when R 1 represents a tertiary alkyl group or represents a hydrogen atom or a chlorine atom when R 1 represents an aryl group, wherein said material is developed in the absence of benzyl alcohol.
Claim 9
Dependent Claim
117 words
The process for forming yellow images as claimed in claim 6, wherein said yellow coupler is represented by formula (II): ##STR54## wherein R 5 represents a substituted or unsubstituted tertiary alkyl group; R 6 represents an unsubstituted alkyl group or an alkyl group substituted by an alkoxy group having from 6 to 20 carbon atoms or a group represented by formula (III), (IV) or (V): ##STR55## wherein R 7 represents an unsubstituted alkyl group or an alkyl group substituted by an alkoxy group having from 1 to 12 carbon atoms and R 8 represents a substituted alkyl group having from 1 to 8 carbon atoms; and R 2 has the same meaning as that in formula (I).
