Abstract:
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, said silver halide emulsion layer containing a pyrazoloazole series magenta coupler represented by general formula [I] ##STR1## wherein, R.sup.1 and R.sup.2 each represents a hydrogen atom or a substituent; and X represents a hydrogen atom or a releasing group which is released at the reaction with the oxidation product of an aromatic primary amine developing agent; at least one of said R.sup.1 and R.sup.2 is an alkyl group having a secondary or tertiary carbon atom directly bonded to the skeleton, at least one of said R.sub.1 and R.sub.2 is a sulfonamidoalkyl group or a sulfamoylalkyl group; and the magenta coupler may form a dimer or more polymer at the position of said R.sup.1, R.sup.2 or X.By the combined use of high boiling point organic solvent and ultraviolet absorbent, light fastness and coloring property are markedly improved.
