Abstract
A process for modifying the surface of raw release papers is described, in which a suspension of film-forming substances is applied within or outside the paper machine by means of conventional applicators to the paper web, if appropriate with the addition of a white pigment, which suspension already contains a fraction of up to 25% of a catalyst in the form of an aqueous emulsion.
