CONCENTRATED COMPOSITION FOR SILVER HALIDE COLOR PAPER AND METHOD OF PROCESSING

WIPO Patent Application WO/2006/019084

A1

A method of processing silver halide color paper that ensures (a) promptness such that finished prints can be handed at shop to customers, (b) small installation area for minilab, (c) processing solution stability capable of withstanding slack seasons, (d) normal image quality, (e) small replenishment solution amount and (f) inhibition of tar generation and sulfuration phenomenon occurrence. There is provided a concentrated composition for color paper that finds application in a processing including the steps of color developer/bleaching/fixing treatments, which concentrated composition comprises a concentrated composition for bleach replenishment of ≤ 3.0 pH containing ≥ 0.3 mol/L of EDTA Fe(III) ammonium, ≥ 0.3 mol/L of sulfinic acid compound of specified structure and ≥ 0.5 mol/L of ammonium bromide together with a concentrated composition for fixative replenishment of ≥4.0 pH containing ≥ 0.7 mol/L of ammonium thiosulfate and ≥ 0.4 mol/L of ammonium sulfite. Further, there is provided a method of processing wherein use is made of the concentrated composition for color paper.
