| titleOfInvention | Processing colour silver halide material |
| abstract | Processing an imagewise exposed photographic silver halide colour material comprising two or more silver halide layers sensitised to different regions of the visible spectrum having associated therewith appropriate dye image forming couplers comprises, during or after a development step which produces a silver image, fixing the material using a fixing agent which does not poison the catalytic properties of the silver image e.g. thiosulphates or thiocyanates to an extent which is more severe than a 30g/l solution of sodium sulphite and subsequently forming a dye image by redox amplification while monitoring the extent of image formation with visible light and making adjustments to the time of treatment or composition of the redox amplifying solution in order to obtain results of a predetermined quality. The fixing agent is preferably a compound of formula N-[(CH 2 ) n -A] p where A is -COOH or -PO 3 H 2 , n is 1-6 and p is 2 or 3. |
