Abstract

Crosslinked polymer microparticles based on epoxy resin obtained by polymerization of aqueous dispersions (A) of compounds containing epoxide groups in the presence of up to 0.2 mol, preferably 0.02 to 0.15 mol (based on the nitrogen contained in (B)) of a nitrogen-containing organic compound (B) per epoxide equivalent and subsequent isolation which are preferably in the form of aqueous dispersions thereof, and are suitable as organic fillers, pigments, matting agents and/or reinforcing agents for binder systems and individual components thereof, paint formulations, coating and molding compositions, intermediate coatings, adhesives and the like, preferably based on water.
