The invention provides a diffusion transfer receiver comprising a support with a non-light-sensitive image receiving layer coated onto each face thereof, said image receiving layer in each case comprising a catalytic nuclei layer for physical development of transferred complexed silver halide and each composite comprising a diffusion modifying active component which is preferably a tone controlling compound. The composites of Side 1 and Side 2 are different constitutions so as to provide receivers suitable for different end users. For example Side 1 can be made suitable for creative designers while Side 2 can be made suitable for pre-sensitized plate-makers. The invention also provides a method for improving transmission density of a receiver sheet in a non-light-sensitive image receiving layer of a silver diffusion transfer process which method comprises utilizing in the receiver layer an S-thiuronium alkyl sulfonate transmission density enhancer.
A diffusion transfer receiver for use in a diffusion transfer photographic process, said diffusion transfer receiver comprising a support and non-light-sensitive image receiver layers exhibiting different imaging characteristics which adapt them for different end uses on each face of said support, each of said image receiver layers including catalytic nuclei for physical development of a transferred silver halide complex and containing different tone controlling compounds to impart said different imaging characteristics thereto.
