Abstract

The disclosure relates to processes for preparing an emulsion containing core-sheath-shell polymer particles which, when dried, contain a microvoid which causes opacity in compositions in which they are contained. The particles can serve as binding or opacifying agents in paints, coating, impregnating, and molding compositions primarily, also extended to paper coatings and to some extent in leather, textiles and water based construction materials.
