AQUEOUS PAINT COMPOSITION AND PROCESS TO REDUCE OR SUPPRESS SURFACE DEFECTS IN PAINT FILMS

摘要

A process to reduce or suppress the formation of surface defects in paint films comprising adding to an aqueous paint composition at least one of homopolymers B of butyl actylate and copolymers BA of butyl actylate and copolymerisable monomers A, characterised in that the mass fraction of moieties arising from the comonomers A in the copolymer does not exceed 30 %, and aqueous paint compositions comprising at least one of homopolymers B of butyl acrylate and copolymers BA of butyl actylate and copolymerisable monomers A.
