Abstract (en)

[origin: EP1742106A1] A concentrated bleach composition for a silver halide color photographic photosensitive material, containing a single liquid including an ethylenediamine-tetraacetic acid-iron (III) complex salt of from 0.10 to 0.42 mol/L as a bleaching agent, an uncomplexed ethylenediaminetetraacetic acid of from 0.5 to 10 mol% with respect to the bleaching agent and a dibasic acid having a pKa of from 2.0 to 5.0 in an amoount from 0.10 to 0.40 mol/L, and having a pH value of from 2.0 to 3.5; and a concentrated one-part composition for a color developer replenisher for a color photographic photosensitive material, containing (A) a p-phenylenediamine color developing agent of from 0.08 to 0.12 mol/L, (B) a substituted hydroxyamine derivative of a specified structure of from 0.06 to 0.16 mol/L and (C) an ethylene glycol compound from 0.05 to 1.0 mol/L, and (D) having a pH value of from 12.5 to 12.8 when diluted to 3.84 times with water, and (E) substantially not containing an alkanolamine. Also a processing method for a silver halide color photographic photosensitive material, wherein a bleach-fix tank is replenished with the composition above and a concentrated fixing composition containing a thiosulfate salt from 1.0 to 3.0 mol/L in a ratio of 1:1, and the bleach-fix step is executed in a period of from 10 to 30 seconds.
