ABSTRACT:
An organic-inorganic composite particle containing an inorganic particle having a plurality of polymer particles attached to the inorganic particle and a polymer layer encapsulating the attached polymer particles. A process is provided for the organic-inorganic composite particle. The organic-inorganic composite particle is useful in the preparation of dried coatings that have improved hiding, whiteness, or gloss.
