Abstract
Aqueous selfcrosslinkable resin composition comprising an aqueous dispersion of at least one polyurethane polymer having anionic salt groups as sole chain-pendant functional group and at least one vinyl polymer having chain-pendant acetoacetoxyalkyl ester groups. A selfcrosslinking reaction between the polyurethane polymer and the vinyl polymer will take place during and/or after film formation, resulting in the formation of a polymeric film having properties not found to be those of the non-functional polymer components.
