Abstract
The present invention is directed to a coating composition or paint comprising a multistage latex with at least first and second stages, wherein the composition or paint is substantially free of volatile organic compounds (VOC) and capable of film formation even in the absence of coalescent agents. The base paint formulation is capable of being tinted at a point-of-sale (i.e. in-store) using a colorant composition of a type and quantity required to produce a paint of desired color and finish. The paints, show improved block resistance, scrub resistance and tack resistance.
