PURPOSE:To prevent color forming fogging and color clouding in the stage of color forming development by incorporating a specific compd. into >=1 layers of photographic constituting layers and executing a color forming development stage in the presence of the specific compd. CONSTITUTION:The compd. expressed by the formula I is incorporated into at least one layer of the photographic constituting layers and the color development stage is executed in the presence of at least one compd. selected from the compds. expressed by the formula II-formula V. In the formula I, R1, R2: an alkyl group, n: 1-20 integer, k: 1 or 2, A: CO-X-R3, etc., X: -O- or NR4-, R4: H, alkyl group, etc. B: an alkyl group, etc. In the formula II, R5: a halogen atom, alkyl group, etc., n1: 0-4 integer, in the formula III, R6, R7: H, R8: a halogen atom, alkyl group, etc., n2: 0-4 integer. In the formula IV, X: H, etc., R9: an aryl group, R10-R13: an alkyl group, etc. In the formula V, Y: S, O. |
