Abstract
Silver halide color photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer containing a) a diacylaminomethylene yellow dye forming coupler having bonded to the coupling active position a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoyl acetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position.
Claims3
A silver halide color photographic light-sensitive material which comprises a support having coated thereon at least one silver halide emulsion layer containing a) a diacylaminomethylene yellow dye forming coupler having, bonded directly to the coupling active position, a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoyl acetanilide yellow die forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position, wherein said alkoxybenzoyl acetanilide yellow dye forming coupler is represented by the general formula (VI):
- ##STR12## wherein R.sub.15 and R.sub.17 each represents an alkyl group of 1 to 4 carbon atoms, a phenyl or naphthyl group, chloro atom, bromo atom or alkoxy group of 1 to 4 carbon atoms;
- m and n are individually 0, 1 or 2;
- R.sub.16 is an alkyl group of 1 to 4 carbon atoms;
- R.sub.18 is a ballast group;
- R.sub.19 represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, a phenyl or naphthyl group or an acyl group;
- R.sub.20 is an alkoxy group of 1 to 16 carbon atoms;
- R.sub.22 is hydrogen atom, an alkyl group of 1 to 16 carbon atoms or a phenyl or naphthyl group;
- R.sub.23 is a halogen atom, and wherein said diacylaminomethylene yellow dye forming coupler is represented by the general formula (III):
- ##STR13## wherein R.sub.11 and R.sub.12 each represents an alkyl group having 1 to 20 carbon atoms, and R.sub.13 and R.sub.14 each represents a lower alkyl group having 1 to 4 carbon atoms.
A silver halide color photographic light-sensitive material which comprises a support having coated thereon at least one silver halide emulsion layer containing a) a diacylaminomethylene yellow dye forming coupler having, bonded directly to the coupling active position, a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said croup is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoyl acetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position, wherein said alkoxybenzoyl acetanilide yellow dye forming coupler is represented by the formula (VIII):
- ##STR14##
A silver halide color photographic light-sensitive material which comprises a support having coated thereon at least one silver halide emulsion layer containing a) a diacylaminomethylene yellow dye forming coupler having, bonded directly to the coupling active position, a group which provides a compound having a development inhibiting property when the group is released from the coupler active position upon the color development reaction, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group and b) an alkoxybenzoyl acetanilide yellow dye forming coupler having a 3-hydantoinyl leaving group bonded to the coupling active position, wherein said diacylaminomethylene yellow dye forming coupler is represented by the formula (IV) or by the formula (V):
