Abstract

1286032 Photographic diffusion transfer AGFA-GEVAERT A G 14 Jan 1970 [25 Jan 1969] 1782/70 Heading G2C In the silver salt diffusion transfer process, development is carried out in the presence of a blue toner of formula: (in which R 1 is H, C 1-3 alkyl, alkoxy-carbonyl or acyl; and R 2 and R 3 are each H or C 2-5 alkoxycarbonyl, at least one of R 2 and R 3 being H). The toner may be in tautomeric form. Preferably the image-receiving layer or developer contains 1-200 mg. m<SP>-2</SP> or l<SP>-1</SP> of the blue toner.
