ABSTRACT:
What is disclosed is a synthetic resin powder of latex particles having an average particle size between 1 micron and 5 microns, which particles can be partially or completely loosely aggregated to form larger particles, said synthetic resin being a cross-linked copolymer of 75 to 99.5 percent by weight of a monomer mixture of methyl methacrylate and isobutyl methacrylate in a weight ratio of 1:3 to 3:1, 0.5 to 10 percent by weight of a cross-linking comonomer having at least two polymerizable double bonds, and 0 to 24.5 percent by weight of a further different ethylenically-unsaturated comonomer copolymerizable therewith, a coating agent containing a binder dissolved or dispersed therein together with such a resin powder, and a method of coating using such a coating agent to give coatings wherein the presence of the resin powder prevents blocking of the coatings without undue loss of luster therein.
