Abstract:
The present invention relates to a process comprising contacting a stable aqueous dispersion of pre-formed polymer particles with a monomer emulsion under emulsion polymerization conditions to form a stable aqueous dispersion of pre-formed particles protuberating from polymer particles arising from the polymerization of the monomer emulsion; these multistage polymer particles show exceptional compatibility with pigment particles. In another aspect, the present invention is a composition relating to the pre-formed particles.
