Abstract

1285535 Photographic processing FUJI PHOTO FILM CO Ltd 9 June 1971 [11 June 1970] 19761/71 Heading G2C An alkaline colour developer for multi-layer colour reversal photographic silver halide material comprises an aromatic primary amine, an alkali metal borohydride and an aliphatic amine of the formula, X-R-NH 2 wherein R is a divalent aliphatic hydrocarbon radical having from 1 to 6 carbon atoms, and X is a hydrogen atom, an amino group, a methylamino group or a dimethylamino group. Numerous examples of suitable aliphatic amines are given. The borohydride may be of sodium, potassium or lithium. Two developer formulations (A and D) in accordance with the invention are given.
