Abstract

1294598 Photographic vesicular images using the silver salt diffusion transfer process AGFA-GEVAERT A G 22 April 1970 [26 April 1969] 19252/70 Heading G2C A photographic process for producing superimprosed silver and vesicular images comprises (a) imagewise exposing a supported silver salt emulsion layer (b) developing the layer whilst in contact with an image-receiving layer containing uniformly distributed development nuclei to produce a silver image in the receiving layer and (c) treating the receiving layer with a compound which is decomposed by the silver image to produce a vesicular image thereon. Hydrogen peroxide, as vapour or in solution, is the specified compound and is applied as in Specification 1196200. The light-sensitive emulsion may be a support coated, in either order, with a gelatine silver halide emulsion and an image-receiving layer containing silver sulphide or silver selenide, the concentration of silver halide and nulei being low (0À1-0À3g per sq m of silver as silver halide and 10<SP>-3</SP> to 10<SP>-4</SP> g per sq m of nuclei). There may be an intermediate algisate layer between silver halide and receiving layers. If the silver halide-emulsion is the top layer, it is washed off during development before the vesicular layer is produced. The vesicular image increases the density of the silver image.
