Abstract
1523616 Photographic silver halide colour developing solution FUJI PHOTO FILM CO Ltd 29 Oct 1975 [31 Oct 1974] 44776/75 Heading G2C A photographic silver halide aqueous alkaline colour developing solution having a pH above 8 contains a primary amino aromatic colour developing agent or a precursor thereof and at least 3À5 - 20g/litre of diethylenetriamine-pentaacetric acid or a salt thereof. When using this colour developing solution it may be followed without the use of any intermediate processing solution by treatment with a bleaching solution containing a ferric iron aminopolycarboxylic acid complex salt. The diethylenetriamine-pentaacetic acid or salt stabilizes the colour developing solution and increases its useful life.
