PURPOSE:To rapidly desilver the title material by incorporating a specified bleach accelerating agent and a specified compd. in a processing solution having bleaching ability. CONSTITUTION:The processing solution having the bleaching ability contains at least one kind of the bleach accelerating agent shown by formula I, etc. And, the processing solution contains at least one kind of the ferric complex salt of a compd. such as ethylene diamine tetraacetic acid, etc., and the ferric complex salt of 1,3-diaminopropane tetraacetic acid in a molecular ratio of the former to the latter of <=3, as bleaching agents. In the formula, A<1> and A<2> are each nitrogen atom., etc., R<1>-R<3> are each hydrogen atom., etc., (q) is 0 or 1, B<1> is a divalent org. group composed of alkylene group, etc., solely or a combination thereof, (h) is 0 or 1, Z<1> is an anion, (i) is 0, 1 or 2. Thus, the rapid desilverization of the sensitive material is permitted. |
