Abstract

1,202,842. Reversal processing of silverdye-bleach materials. AGFA GEVAERT A. G. Jan.29, 1969 [Feb.28, 1968], No.4827/69. Heading G2C. Photographic silver-dye-bleach colour materials are reversal processed to give a negative colour image by giving a first development; silver-bleaching, fogging, second development, dye-bleaching and bleach-fixing, using as a foggant in the second developer or in a bath given prior to the second development a compound of the formula: - where R 1 , R 2 and R 3 are each hydrogen or alkyl. Dimethylamine borane and diethylamine borane are specified.
