Definitions
- a substantially protein free receiving layer for use in a photographic diffusion transfer process comprises silver precipitants and a colloid binder comprising from about 50 to about 95% by weight polyvinyl alcohol based on the total binder and from 5 to about 50% sulfonated aromatic polymer, such as a sulfonated polysytrene or a salt of a sulfonated polymer.
- the layer can also contain toning and/or processing compounds.
- the layer is typically coated on a support and used in the silver salt photographic diffusion transfer process to provide an image in the receiving layer on a support.
