Abstract
Coating compositions or paint having a pigment blended with a polymer system including one or more latex polymers, wherein the polymer system contains an alkali-soluble resin having an acid value and molecular weight and provided in a preferably desired amount to demonstrate optimal performance characteristics of washability, stain resistance or scrubability without negatively impacting block resistance, especially when neutralized with a low-volatility base.
