Abstract

1,149,794. Photographic silver halide colour developers. ILFORD Ltd. Dec.13, 1967 [Dec.14, 1966], No.56035/66. Heading G2C. A photographic silver halide colour developer contains as colour developing agents an N:N- dialkyl-p-phenylene diamine developing agent and a compound of the formula:- where R 1 and R 2 are each hydrogen, methyl or methoxy. The N:N-dialkyl-p-phenylene diamine developing agent may be substituted in the phenylene ring with methyl groups and the N- alkyl groups may be substituted.
