ABSTRACT:
A photographic light-sensitive material is described comprising a support having thereon at least two silver halide photographic emulsion layers capable of forming a silver image upon treatment with an alkaline processing solution in the presence of a developing agent for silver halide after exposure, said material containing an interlayer positioned between said emulsion layers, wherein the improvement comprises said interlayer containing a complex which is formed from a mixture of hydroquinone derivatives having a solidifying point of 100.degree. C. or less, and which are different compounds from the developing agent for silver halide used in the treatment of the material, and a homopolymer or copolymer containing a recurring unit represented by formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group; Q represents of chemical bond, --COOR.sub.2 -- or --CONHR.sub.2 --; A represents a chemical bond or an oxygen atom; B represents a chemical bond or ##STR2## D represents --CH=CH).sub.2 or --CH.sub.2).sub.n, wherein n represents an integer of 3 to 5 when A and B are both chemical bonds, an integer of 2 or 3 when A is an oxygen atom and B is a chemical bond, or an integer of 2 to 4 when A is a chemical bond and G is ##STR3## or D represents ##STR4## when A is a chemical bond and B is ##STR5## and R.sub.2 represents a substituted or unsubstituted divalent hydrocarbon group having 2 to 8 carbon atoms.
The photographic light-sensitive material provides color images having excellent color separation.
