ABSTRACT:
The adherence of hydrophilic layers to dimensionally stable polyester films is improved by means of an adhesive layer by a process comprising applying the adhesive layer to an at most monoaxially stretched polyester film, stretching the thus covered polyester film biaxially or in a direction perpendicular to the first stretching direction and heat-setting the thus treated film at 180.degree.-225.degree. C, whereafter a hydrophilic coating is applied to the heat-set adhesive layer. This adhesive layer consists essentially of about 25-60% by weight of a chlorine-containing copolymer, 15-40% by weight of a butadiene copolymer, and 2-10% by weight of a water-soluble melamine-formaldehyde or hydandoin-formaldehyde resin and is free of gelatin.
