Abstract: Copolymers and latex paint compositions using such copolymers that are heat-age stable and provide good adhesion, block resistance, and hiding all while using lower amounts of titanium dioxide are described herein. In one aspect, the heat-age stable compositions include an acrylic, styrene acrylic, vinyl acrylic copolymer or blends thereof including, as additional polymerizable units, at least one polymerizable phosphate surfactant and at least one linear or branched hydrophobic monomer that are both polymerized into the acrylic, styrene acrylic, vinyl acrylic copolymer backbone.

Abstract: A high quality paint formulation comprises water, latex polymer, pigment, and a quaternary ammonium compound. The high quality paint is capable of killing gram positive bacteria, gram negative bacteria at a rate of greater than 3 logs within 2 hours of application of bacteria to a painted surface. The high quality paint is also capable of inactivating viruses.

Abstract: A high quality paint comprises water, latex polymer, pigment, and biocidal agent. The coating provided by the high quality paint may be capable of killing gram positive bacteria, gram negative bacteria at a rate of greater than 3 logs within 2 hours of application of bacteria to a painted surface. The coating provided by the high quality of paint may be capable of continuing to kill gram positive bacteria, gram negative bacteria at a rate of greater than 1 log within 2 hours even after repeated contamination of the surface. The coating provided by the high quality paint may be capable of delivering residual killing of gram positive bacteria, gram negative bacteria for up to 48 months. The coating provided by the high quality paint may also be capable of inactivating viruses.
