Coating compositions comprising polymer blends

摘要

Coating compositions comprising intimate blends of a poly(vinyl acetal) and a low molecular weight polystyrene or poly( alpha -methylstyrene). The coating compositions may contain up to 500 parts by weight of an inert non-photoconductive pigment per 100 parts by weight of polymer blend. The compositions are useful for the preparation of electrographic recording media which possess improved toner adhesion.
