Abstract
The present invention relates to a composition comprising stable aqueous dispersion of polymer particles with acorn morphology, a hydrophobically modified ethylene oxide urethane based rheology modifier (HEUR) and a substantial absence of pigment particles with a refractive index in the range of from 2.0 and 3.0. The composition imparts improved HEUR efficiency for coating compositions such as deep base coating compositions.
