ABSTRACT:
The present invention is concerned with a process for preparing aqueous dispersions from solid polymer precursors which are polyester or polyurethane oligomers containing both hydrophilic centers and cross-linking sites and subsequently coating substrates with the thus obtained dispersions. The aqueous dispersion is applied to a substrate and dried with resultant cross-linking of the film.
