Title:
PROCESSING METHOD FOR PHOTOGRAPHIC SILVER HALIDE MATERIAL
Document Type and Number:
Japanese Patent JPH09166857
Kind Code:
A
Abstract:

To provide a processing method using a sulfurous acid fixer to minimize the number of stages.

The respective layers in this method include at least two dye forming layer units which contain at least 85mol% silver chloride and respond to regions of different spectra. The processing of the silver halide material which contains color couplers and is subjected to imagewise exposure is executed by such layer units. In such a case, dye images are first formed. Next, the formation of the dye images is stopped and the material is processed with a bath contg. a fixing agent which does not hinder the bleaching in the next bleaching bath at need. The material is thereafter bleached by a first bleaching bath contg. hydrogen peroxide or a material for providing the hydrogen peroxide and alkali metal halide as the bleaching agent. Next, the material is fixed with a fixing bath contg. alkaline metal sulfite or sulfite as a fixing agent and is processed with a bath of ≤pH5 contg. a colorless oxidizing agent for decomposing the sulfurous acid ions. The material is thereafter subjected to washing or stabilizing.
