The present invention relates to a silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein at least one layer of said photographic material contains at least one yellow coupler represented by the following general formulas (3) or (2): ##STR1## as defined in the specification.

Silver halide color photographic material

A silver halide color photographic material is provided comprising on a support at least one silver halide emulsion layer containing at least one of the compounds represented by formulae (I) to (III): ##STR1## wherein R.sub.11 represents ##STR2## in which R.sub.13 represents an alkyl, aryl or heterocyclic group, and R.sub.14 and R.sub.15 each represents hydrogen, alkyl group or aryl group; R.sub.12 represents a substituent having a Hammett's substituent constant .sigma.p of 0.3 or less; n represents an integer 0 to 2, and when n is 2, the two R.sub.12 's may be the same or different; B represents a group which releases PUG after being separated from a hydroquinone nucleus; PUG represents a development inhibitor; l represents an integer; and A and A' each represents hydrogen or a group capable of being removed by an alkali; R.sub.11 and R.sub.12, R.sub.11 and A or A', R.sub.12 and A or A', and two R.sub.12 's may together form a ring; ##STR3## wherein Q.sup.1 represents an atomic group containing at least one hetero atom and is required for the formation of a heterocyclic group containing 5 or more members together with carbon atoms connected thereto; R.sup.21 represents a group capable of substituting on the hydroquinone nucleus; and B, PUG, l, A and A' are as defined above; ##STR4## wherein R.sub.31 represents an alkyl group containing two or more carbon atoms in which the carbon atom adjacent to the carbonyl group is not substituted by a hetero atom, a cycloalkyl group, an aryl group or a heterocyclic group; R.sub.32 and R.sub.33 each represents hydrogen or a substituent having a Hammett's substituent constant .sigma.p of 0.3 or less; and B, PUG, l, A and A' are as defined above.

A color light sensitive material which provides a positive dye image having high density, good color reproducibility and which exhibits excellent preservability before use. The material comprises a support having provided thereon a light-sensitive silver halide, a binder, a reducible dye donating compound, and at least one reducing agent selected from the group consisting of a compound represented by formula (IA) and a compound represented by formula (IB): ##STR1## wherein the substituents have the meanings indicated in the specification.

Color light-sensitive material

A silver halide color photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer containing a color coupler, at least one layer of the material containing a compound represented by formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6, which may be the same or different, each represents hydrogen, a halogen atom, a sulfo group, a carboxyl group, a cyano group, an alkyl group, an aryl group, an acylamino group, a sulfonamido group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, an acyl group, an acyloxy group, a sulfonyl group, a carbamoyl group, an alkoxycarbonyl group or a sulfamoyl group; provided that R.sup.1 and R.sup.2, or R.sup.4 and R.sup.5 may each be linked to form a carbon ring or a heterocyclic ring; and Z represents a single bond or a divalent linking group. The silver halide color photographic material provides an image having an improved white background and gradation, and low minimum image density.
