PURPOSE:To perform desilvering of a highly sensitive color negative sensitive material having high picture quality rapidly by incorporating a ferric complex salt of a specified compd. and a ferric complex salt of 1,3-diaminopropane tetraacetic acid into a treating soln. having bleaching effect as a bleaching agent. CONSTITUTION:At least one kind of ferric complex salt of (A-1) ethylenediamine tetraacetic acid, (A-2) diethylenetriamine pentaacetic acid, (A-3) cyclo- hexanediamine tetraacetic acid, and (A-4) 1,2-propylenediamine tetraacetic acid, is incorporated as a bleaching agent together with a ferric complex salt of 1,3-diaminopropane tetraacetic acid into a treating soln. having bleaching effect in <=3:1 proportion of the former to the latter, by molar ratio. Thus, a highly sensitive color negative photographic sensitive material is processed rapidly. |
