Claims
- 1. A silver halide color photosensitive material comprising a support having thereon at least one hydrophilic colloidal layer containing at least one dye forming coupler represented by formula (XX) or (XXI): ##STR27## wherein EWG represents an electron withdrawing group having a Hammett's .sigma..sub.p value of not less than 0.3; R.sub.1 and R.sub.2 each represent a substituent; and X represents hydrogen atom or a group releasable on a coupling reaction with an oxidation product of an aromatic primary amine developing agent.
- 2. A silver halide color photosensitive material according to claim 1, wherein EWG is selected from the group consisting of a cyano group, a nitro group, an aliphatic or aromatic acyl group, a carbamoyl group, a phosphono group, an alkoxycarbonyl group, a phosphoryl group, an aliphatic or aromatic sulfamoyl group, an aliphatic or aromatic sulfonyl group, and a perfluoroalkyl group.
- 3. A silver halide color photosensitive material according to claim 1, wherein R.sub.1 and R.sub.2 each represent a substituent selected from the group consisting of an aliphatic group having from 1 to 36 carbon atoms, an aromatic group having from 6 to 36 carbon atoms, a heterocyclic group, an alkoxy gorup, an aryloxy group, an alkenyloxy group, an amino group, an acyl group, an aliphatic or aromatic oxycarbonyl group, an acyloxy gorup, an aliphatic or aromatic oxysulfonyl, an amido group, a carbamoyl group, a sulfonamido group, a sulfamoyl group, a sulfamido group, an imido group, a ureido group, an aliphatic or aromatic sulfonyl group, an aliphatic or aromatic thio group, a hydroxyl group, a cyano group, a carboxyl group, a nitro group, and a sulfo group.
- 4. A silver halide color photosensitive material according to claim 1, wherein X is selected from the group consisting of a hydrogen atom, a halogen atom, an alkoxy group, an aryloxy group, an acyloxy group, an aliphatic or aromatic sulfonyloxy group, an acylamino group, an aliphatic or aromatic sulfonamido group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an aliphatic, aromatic or hetercyclic thio group, a carbamoylamino group a 5- or 6-membered nitrogen-containing hetrocyclic group, an imido group, an aromatic azo group, and a carboxyl group.
- 5. A silver halide color photosensitive material according to claim 1, which contains the coupler of formula (XX) or (XXI) in an amount of from 1.times.10.sup.-3 to 1 mol per mol of silver halide.
