Abstract:
A releasing agent comprising an aqueous dispersion of a resin having a structure in which a vinyl copolymer is covered with a polyurethane, the resin prepared from (a) a vinyl copolymer which is prepared from a perfluoroalkyl group-containing ethylenically unsaturated monomer and/or polydimethylsiloxane group-containing ethylenically unsaturated monomer and another ethylenically unsaturated monomer copolymerizable therewith and (b) a water-dispersible polyurethane containing in combination a polydimethylsiloxane group and a hydrophilic group, where said aqueous dispersion of the resin is obtained by dispersing the copolymer (a) in water in the presence of the water-dispersible polyurethane (b).
