Abstract: The present invention relates to a composition comprising an aqueous dispersion of submicron-sized polymer particles and micron-sized polymer beads, wherein the polymer particles or beads or both are functionalized with phosphorus acid groups. The composition of the present invention is useful for providing a matte finish on substrates, such as leather, textiles, wallboard, decorative coatings, concrete, and wood, with improved stain resistance. The present invention also relates to a leather substrate coated with a clear matte finish comprising an acrylic or styrene-acrylic polymer film and micron-sized polymer beads, wherein the film or the beads or both are functionalized with a phosphorus acid monomer.

Abstract: The present invention is an above-critical coating composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles wherein the polymer particles comprise, in a single phase and based on the weight of the polymer particles, from 35 to 79.9 weight percent structural units of vinyl acetate and from 0.1 to 6 weight percent structural units of a phosphorus acid monomer or a salt thereof, wherein the polymer particles have a particle size by dynamic light scattering of from 250 nm to 500 nm. The above-critical composition shows surprising improvements in hiding with increasing particle size of the polymer particles.

Abstract: The present invention relates to composition comprising an aqueous dispersion of microspheres and a class of a nonionic polyalkylene oxide of a distyryl or tristyryl phenol or an anionic polyalkylene oxide salt of a distyryl or tristyryl phenol and a process for preparing the composition. The microspheres have an average particle size in the range of from 1 μm to 25 μm, as well as a low coefficient of variation and low gel concentration; the composition is useful in coatings applications, especially where a matte finish is desired.

Abstract: A process for making preseed particles comprising, consisting of, or consisting essentially of the steps of: mixing initial seed latex particles; a monomer mixture comprising at least one monomer and at least one copolymerizable surfactant, at least one initiator and a chain transfer agent, is disclosed. The preseed particles, a monomer mixture comprising at least one monomer and at least one copolymerizable surfactant, and at least one initiator can then be mixed to form oligomer seed particles. The oligomer seed particles can be used to produce acrylic beads.
