Document Type and Number:
WIPO Patent Application WO/2005/106583
Kind Code:
A1
Abstract:
A single-solution type bleach concentrate composition for silver halide color-photographic photosensitive materials which contains ethylenediaminetetraacetato iron(III) as the bleaching agent in a concentration of 0.10 to 0.42 mol/L, free ethylenediamine- tetraacetic acid in an amount of 0.5 to 10 % by mole based on the bleaching agent, and a dibasic acid having a pKa of 2.0 to 5.0 in a concentration of 0.10 to 0.40 mol/L and has a pH of 2.0 to 3.5; a one-part type concentrate composition for replenishment color developers for color photographic materials which contains (A) p-phenylenediamine color developing agent in a concentration of 0.08 to 0.12 mol/L, (B) a substituted hydroxylamine derivative having a specific structure in a concentration of 0.06 to 0.16 mol/L, and (C) an ethylene glycol in a concentration of 0.05 to 1.0 mol/L and which exhibits a pH of 12.5 to 12.8 in a state diluted with water 3.84-fold and is substantially free from alkanolamines; and a process for processing silver halide color-photographic materials which comprises replenishing a bleach-fix tank with the composition and a fixing agent concentrate composition containing a thiosulfate salt in a concentration of 1.0 to 3.0 mol/L at a ratio of 1 : 1 and conducting bleach-fix in 10 to 30 seconds.
