More Information
Summary:Aqueous polymer dispersions useful in coating compositions comprise cationically, anionically or nonionically stabilised particles in which the particles comprise (a) polymeric modifier as defined, (b) addition polymer, and (c) crosslinking agent, both (a) and (b) containing reactive groups and (c) containing complementary reactive groups. Preferably the dispersions are prepared by polymerising a solution of (a) and (c) in the monomer precursor of (b).
