Abstract
Abstract WHEREIN R4, R5, R6 and R7 each represent a member selected from the group consisting of a hydrogen atom, an alkyl group, a halogen atom, a carboxylic acid group, a sulfonic acid group, and -CH NOH; p is 2 or 3, q is 0 or 1, and p + q is always 3. WHEREIN R1 represents a member selected from the group consisting of a hydrogen atom, an alkyl group, an allyl group, an aryl group and NHR3; R2 and R3 represent a member selected from the group consisting of a hydrogen atom, an alkyl group, a carboxyalkyl group, a sulfoalkyl group, an allyl group and an aryl group; said R1 and R2 may combine with each other to form a 5-membered or 6-membered heterocyclic ring; X represents 0 or NH; and k, m, and n are 0 or 1, and B. AT LEAST ONE COMPOUND REPRESENTED BY THE GENERAL FORMULA (2): In a process for preventing the discoloration of a color image by developing an exposed silver halide color photographic material, removing the silver image thus formed together with the residual silver halide and stabilizing the thus formed color image with a stabilizing solution, the improvement which comprises employing a stabilizing solution containing: A.
