Abstract
A silver halide color photographic light-sensitive material comprising a support and red-sensitive, green-sensitive and blue-sensitive light-sensitive layers formed on the support. The light-sensitive layers separately contain a coupler of formula (I), a coupler of formula (II) or (III), and a coupler of formula (IV). ##STR1## This novel combination of couplers leads to good color formability, improved color reproducibility, improved image preservability and good color balance.
Claims20
A silver halide color photographic light-sensitive material comprising a support and red-sensitive, green-sensitive and blue-sensitive light-sensitive layers formed on the support, said light-sensitive layers separately containing a coupler represented by the following formula (I), a coupler represented by the following formula (II) or (III), and a coupler represented by the following formula (IV):
- ##STR23## wherein R.sub.1 represents a substituted or unsubstituted divalent aliphatic group,
- R.sub.2 represents a phenyl group substituted by at least one cyano group, or a phenyl group substituted by at least one chlorine atom at the ortho-position,
- R.sub.3 represents a hydrogen atom, a halogen atom, or a substituted or unsubstituted alkyl or alkoxy group,
- n represents an integer of 1 to 5, and when n is 2 or more, the R.sub.3 substituents may be identical or different,
- R.sub.4 and R.sub.5 each represents a substituted or unsubstituted phenyl group,
- R.sub.6 represents a hydrogen atom, an acyl group or an aliphatic or aromatic sulfonyl group,
- R.sub.7 represents a hydrogen atom or a substituent,
- R.sub.8 represents a substituted or unsubstituted N-phenylcarbamoyl group,
- Z.sub.a, Z.sub.b and Z.sub.c each represents methine, substituted methine, .dbd.N-- or --NH--,
- Y.sub.1, Y.sub.2, Y.sub.3 nad Y.sub.4 each represents a hydrogen atom or a group which can be split off during the coupling reaction with the oxidation product of a developing agent,
- a dimer or a polymer may be formed by R.sub.2, R.sub.3 or Y.sub.1 ;
- R.sub.4, R.sub.5 or Y.sub.2 ;
- R.sub.7, Y.sub.3 or Z.sub.a, Z.sub.b or Z.sub.c which is substituted methine;
- or R.sub.8 or Y.sub.4, and
- the aliphatic group above is linear, branched or cyclic, and saturated or unsaturated.
