| titleOfInvention | Color photographic material |
| abstract | A silver halide color photographic material is disclosed, the material having at least one silver halide emulsion layer containing substantially no silver iodide and comprising silver chloride or silver chlorobromide grains having an average silver chloride content of not less than 10 mol% and containing at least 10- 9 mol (per mol of silver halide) of Group VIII metal ion of the Periodic Table, Group II transition metal ion of the Periodic Table, lead ion or thallium ion provided on a reflection type support, characterized in that said silver halide emulsion layer contains at least one member of pyrazoloazole couplers represented by the following general formula (I) and said silver halide color photographic material contains at least one member of compounds represented by the following general formulas (II) and (III) and at least one member of compounds represented by the following general formula (IV)n wherein Za and Zb represent eachn or = N-; R 1 and R 2 represent each hydrogen atom or a substituent group; X, represents hydrogen atom or a group which is eliminated by the coupling reaction with the oxidant of an aromatic primary amine developing agent; when Za = Z b linkage is a carbon-to-carbon double bond, the linkage may be a portion of the aromatic ring; a dimer or polymer may be formed by Ri, R 2 or X 1 ; at least one of R 1 and R 2 is a group which is attached to pyrazoloazole nucleus through secondary or tertiary carbon. R 3 (̵A)̵ n -X 2 (II)n wherein R 3 and R4 represent each an aliphatic group, an aromatic group or a heterocyclic group; X 2 represents a group which is eliminated by the reaction with an aromatic amine developing agent; A represents a group which forms a chemical bond by the reaction with an aromatic amine developing agent; n represents 1 or 0; B represents hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, an acyl group or a sulfonyl group; Y is a group which accelerates the addition of the aromatic amine developing agent to the compound having the formula (III); and R 3 and X 2 or Y and R 4 . or B may be combined together to form a ring structure. D-S-M 2 (IV) nwherein M 2 represents hydrogen atom, a cation or -S-D; and D represents a residue of a heterocyclic ring containing at least one nitrogen atom. |
