Silver halide photosensitive material for color photography and color image forming method

A silver halide photosensitive material for color photography comprising a substrate carrying thereon a photographic constituent layer including at least one photographic photosensitive layer containing a photosensitive silver halide, wherein said photosensitive material comprises at least one silver halide emulsion in which the variation coefficient of the particle size of contained silver halide particles is 15% or less and the variation coefficient of a halogen composition between particles is 25% or less, said silver halide emulsion comprising silver iodide bromide particles of normal crystal, and further comprises a compound represented by any one of the following general formulae [I], [II] and [III], and comprises a color coupler which is capable of forming a diffusible dye by a coupling reaction with the compound represented by any one of the following formulae [I], [II] and [III]:

• wherein, Z represents a carbamoyl group, acyl group, alkoxycarbonyl group, aryloxycarbonyl group, sulfonyl group or sulfamoyl group, and Q represents an atom group forming an unsaturated ring with C;
• and
• wherein, in the general formula [II], R1 to R4 each independently represents a hydrogen atom or a substituent, A represents a hydroxyl group or a substituted amino group, X represents a connecting group selected from —CO—, —SO—, —SO2—, —(Q)PO— (Q represents a monovalent group connected to a phosphorus atom), Y2 represents a bivalent connecting group, Z2 represents a group that is a nucleophilic and can attack X when the present compound is oxidized, and two or more atoms optionally selected from R1 and R2, R3 and R4, and substituents thereof may be each independently connected to form a ring,
• and in the general formula [III], R1 to R4, A and X are as defined for the general formula [II], Yk and Zk represent a nitrogen atom or a group of —CR5═ (herein, R5 represents a hydrogen atom or substituent), k represents an integer of 0 or more, D represents a proton dissociating group or a group which can be a cation, and two or more atoms optionally selected from R1 and R2, R3 and R4, and Yk, Zk and D and substituents thereof may be each independently connected to form a ring.
