    • A silver halide color photographic material in disclosed which comprises a support having thereon at least one silver halide emulsion layer, wherein the photographic material contains at least one compound represented by general formula (I) and at least one compound represented by general formula (II) in combination:Cp--(TIME).sub.n --X--Dye (I)wherein Cp represents a coupler residue capable of releasing --(TIME).sub.n --X--Dye upon coupling with an oxidation product of an aromatic primary amine developing agent; TIME represents a timing group; n represents 0 or a positive integer; Dye represents a dye residue, and X represents an auxochromic group of said dye; ##STR1## wherein R represents a hydrogen atom or a substituent; Y represents a hydrogen atom or a coupling-off group; Za, Zb and Zc each represents a methine group, a substituted methine group, .dbd.N-- or --NH--; either the Za--Zb bond or the Zb-Zc bond represents a double bond and the other represents a single bond, provided that when Za, Zb or Zc represents a substituted methine group, one of the substituted methine group or R may be a divalent group capable of linking to form a dimer or higher polymer, and provided that Y does not represent --(TIME).sub.n --X--Dye as defined in general formula (I). The photographic material has improved sharpness and color reproducibility.

    • A silver halide photographic light-sensitive material is described, comprising a support having thereon a light-sensitive silver halide emulsion layer having associated therewith a blocked photographic agent represented by formula (I) ##STR1## wherein A represents a photographically useful agent moiety, which may have a timing group; X.sup.1 and X.sup.2 each represents a carbonyl group, a sulfonyl group, or a sulfinyl group; Z represents an atomic group forming a 5-membered, 6-membered, or 7-membered ring; R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an aryl group, an alkoxy group, an acyl group, a sulfonyl group, or a heterocyclic group; R.sup.3 represents an alkyl group, an alkenyl group, a cycloalkyl group, a heterocyclic group, an aryl group, or an aralkyl group; m represents 0, 1, or 2; n represents 0 or 1; and the total of m+n is 1, 2, or 3. The precursor of photographic agent is completely stable during the preservation of the photographic light-sensitive material and releases a photographically useful agent at a desired time during processing of the photographic light-sensitive material. The precursor can exhibit its function to a substantial degree under mild conditions, such as in a pH range of from 9 to 12.
