Abstract
A silver halide color photographic material is disclosed which comprises a support having thereon at least one light-sensitive silver halide emulsion layer. The silver halide color photographic material contains a developing solution-deactivated type timing DIR which forms either a nondiffusing dye or a dye dissolved out from the light-sensitive material during development and an acylacetamide type coupler having a specific acyl group and/or an N,N-substituted linear or cyclic malondiamide type coupler.
Claims12
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide color photographic material contains (i) at least one compound represented by the following general formula (II) and (ii) at least one coupler represented by the following general formula (1) and (2):
- A.sub.2 -(TIME).sub.a -DI (II)
- wherein A.sub.2 represents a group which does not have a non-diffusing group and releases (TIME).sub.a -DI by reaction with an oxidant of an aromatic primary amine developing agent;
- TIME represents a timing group which releases DI by cleavage between TIME and DI after release thereof from A.sub.2 ;
- DI represents a development restrainer which is substantially deactivated after DI is dissolved out from the photographic material into a developing solution;
- and a represents 1 or 2 and when a is 2, the two TIME groups may be the same or different;
- ##STR27## wherein X.sub.1 and X.sub.2 each represents an alkyl group, an aryl group or a heterocyclic group;
- X.sub.3 represents an organic group necessary for forming a nitrogen containing heterocyclic group together with >N--;
- Y represents an aryl group or a heterocyclic group;
- and Z represents a group which is eliminated when the coupler is reacted with an oxidant of a developing agent;
- with the proviso that a moiety other than Z in a coupler represented by formula (1) or (2) contains a non-diffusing group.
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide color photographic material contains (i) at least one compound represented by the following general formula (II) and (ii) at least one acylacetamide coupler having an acyl group represented by the following general formula (YI) and at least one coupler represented by the following general formula (1) or (2):
- A.sub.2 -(TIME).sub.a -DI (II)
- wherein A.sub.2 represents a group which does not have a non-diffusing group and releases (TIME).sub.a -DI by reaction with an oxidant of an aromatic primary amine developing agent;
- TIME represents a timing group which releases DI by cleavage between TIME and DI after release thereof from A.sub.2 ;
- DI represents a development restrainer which is substantially deactivated after DI is dissolved out from the photographic material into a developing solution;
- and a represents 1 or 2 and when a is 2, the two TIME groups may be the same or different;
- ##STR28## wherein R.sub.1 represents a substituent group;
- and Q represents a nonmetallic atomic group required for forming a three-membered to five-membered hydrocarbon group together with C or a three-membered to six-membered heterocyclic ring having at least one hetero-atom, as a member of the ring, selected from the group consisting of N, O, S and P, with the proviso that a non-diffusing group is present in the acylacetamide coupler in a moiety other than a releasing group;
- ##STR29## wherein X.sub.1 and X.sub.2 each represents an alkyl group, an aryl group or a heterocyclic group;
- X.sub.3 represents an organic group necessary for forming a nitrogen containing heterocyclic group together with >N--;
- Y represents an aryl group or a heterocyclic group;
- and Z represents a group which is eliminated when the coupler is reacted with an oxidant of a developing agent;
- with the proviso that a moiety other than Z in a coupler represented by formula (1) or (2) contains a non-diffusing group.
