ABSTRACT:
An image receiving material for a silver salt diffusion transfer process comprising a support and at least one image receiving layer, wherein the image receiving layer comprises a binder made up of gelatin, physical development nuclei and polysaccharides having a viscosity of 3 to 200 cp when measured in a 5% aqueous solution at 25.degree. C., with a ratio of the polysaccharides/gelatin being from about 1/10 to 8/10 by weight, and the same or different image receiving layer comprises a surface active agent represented by the following formula (I): ##STR1## wherein R represents an alkyl group having from 8 to 24 carbon atoms or ##STR2## (wherein R.sup.1 represents an alkyl group having from 1 to 18 carbon atoms, and R.sup.2 represents a hydrogen atom or an alkyl group having from 1 to 18 carbon atoms, provided that the total number of carbon atoms of R.sup.1 and R.sup.2 is at least 6); A represents an alkylene group having from 2 to 4 carbon atoms; m is an integer of from 0 to 6; n is an integer of 0 to 12; p is 0 or 1; and M represents an alkali metal, an alkaline earth metal, an ammonium group or a substituted ammonium group. The image receiving layer of the image receiving material is brought into face-to-face contact with the exposed silver halide photographic emulsion of a light-sensitive material and processed by a silver salt diffusion transfer process.
The image receiving material according to the invention provides transfer images without marks or shear in transfer, and has superior stripping facility.
