  • Opacified latex paint containing plastic polymer particles
    Patent number: 4069186
    Abstract: An opacified latex dispersion paint composition comprises film-forming latex binder having a major weight proportion of polymer particles not smaller than about 1,000 A, non-film-forming plastic polymer particles having a weighted average particle size diameter between about 1,000 A and 10,000 A, and opacifying pigment. The latex paint is compounded at a pigment-volume-content (PVC) greater than the critical-PVC as measured by opacity and provides improved opacified paint film having excellent film integrity properties.
