Abstract
1,086,510. Silver halide diffusion transfer process. GEVAERT PHOTO-PRODUCTEN N. V. Dec.16, 1964 [Dec.16, 1963], No. 51234/64. Heading G2C. Silver halide complex diffusion transfer process comprises bringing an imagewise exposed supported silver halide emulsion layer, containing a p-aminophenol developing agent, into contact with an image receiving layer containing an optionally substituted hydroquinone and development nuclei and/or substances capable of forming such nuclei in situ, in the presence of a silver halide complexing agent, developing with an aqueous alkaline solution and separating the layers. Various p-aminophenols and their salts are specified. The developing solution may contain an alkali hydroxide, carbonate or phosphate as alkali, a developing agent, KBr, calcium sequestering agents or blacktoning agents. Image receiving sheet preferably comprises supported layer of a water-permeable colloid or latex (e.g. carboxymethylcellulose or its chromium salt), development nuclei (many are specified), pigments, colloidal silica, preserving agent (e. g. a bisulphite, metabisulphite or aldehyde bisulphite), sodium, sulphite, silver halide complexing agent (e.g. hypo), or black toning agents. In an embodiment the light-sensitive layer may be overcoated with a layer of waterpermeable colloid, or the light-sensitive and receiving layers may be in a single multilayer material. Reference has been directed by the Comptroller to Specification 1,003,783.
