Abstract
A fast drying latex composition comprising a hydroxyl functional polyester modified with a polyfunctional isocyanate is provided. The modification increases polymer molecular weight by chain extension. Such a fast drying latex composition can be utilized in a coating composition with or without a pigment. The fast drying latex composition does not adversely affect the stability of the polyester latex, and in some situations, may stabilize inherently unstable polyester latexes.
