Abstract
An image receiving element for use in a silver salt diffusion transfer process comprising at least an alkali neutralization layer, a neutralization timing layer and an image receiving layer containing silver precipitation nucleus material in regenerated cellulose obtained by saponfying a cellulose ester with a substantially water free alkaline solution after coating disposed on a support in the recited order, wherein the alkaline solution contains from 1 to 20% by weight of a polyhydric alcohol having two or more hydroxyl groups or a derivative thereof. Saponification carried out for forming the image forming layer can be kept from progressing into the layers situated below, thereby enabling the obtainment of satisfactory image receiving sheets with less increase in stains, less density lowering in the storage stability, and less change in the tone.
