ABSTRACT:
A photographic element having a photographic layer such as silver halide emulsion layer, protective layer, intermediate layer, subcoat layer, diffusion transfer image-receiving layer, antihalation layer and backing layer, can be improved in the adhesion between the layer and support, little curling on drying, and flexibility of the layer, by incorporating into the photographic layer a conversion mixture of a polyvinyl alcohol having a saponification degree of 96% or more and an ethylene-maleic anhydride copolymer.
