The present invention relates to copolymers and latex paint compositions using such copolymers that are stable to thermal aging and provide good adhesion, blocking resistance, and coverage, while using lower amounts of pigment. In one aspect, the heat aging stable compositions include a copolymer of acrylic, styrene acrylic, vinyl acrylic or blends thereof including, as additional polymerizable units, at least one polymerizable phosphate surfactant and at least one linear or branched hydrophobic monomer which are both polymerized in the backbone of acrylic copolymer, acrylic styrene, acrylic vinyl. |
