Claims14
A silver halide photosensitive material comprising a support and a silver halide emulsion layer which layer comprises an aldehydebis type magenta coupler represented by the formula ##STR16## wherein A and B individually represent a 5-pyrazolone coupler residue or a pyrazolino-(1,5-a)-benzimidazole coupler residue, and X represents hydrogen, an alkyl group, an alkenyl group, an aralkyl group, a cycloalkyl group, a cycloalkenyl group, an aryl group or a 5- or 6-membered heterocyclic or condensed heterocyclic ring containing at least one member selected from nitrogen, oxygen or sulfur, and an amide compound represented by the formula ##STR17## wherein R.sub.1, R.sub.2 and R.sub.3 individually represent hydrogen, an aliphatic hydrocarbon residue, phenyl or .alpha.- or .beta.-naphthyl which may have at least one substituent selected from alkyl having 1-15 carbon atoms, halogen, alkoxy, having 1-15 carbon atoms, amino which may be substituted with one or more alkyl groups, provided that at least one of the R.sub.1, R.sub.2 and R.sub.3 represents the residue or group containing not less than 6 carbon atoms, and R.sub.1 and R.sub.2 or R.sub.2 and R.sub.3 can cooperatively form a 5- to 7-membered heterocyclic ring.
