ABSTRACT:
The present invention concerns an aqueous resin dispersion comprising a copolymer of a perfluoroalkyl group-containing ethylenically unsaturated monomer and/or polydimethylsiloxane group-containing ethylenically unsaturated monomer and another ethylenically unsaturated monomer copolymerizable therewith dispersed in water in the presence of a water-dispersible polyurethane containing a polydimethylsiloxane group such as silicone and a hydrophilic group such as a carboxylate group. The aqueous resin dispersion of the present invention provides a release agent which can freely control releasability, be excellent in adhesion to a substrate, and undergo little migration to back face or little change in releasability with time.
