Abstract: The overall performance of water-reducible polymer dispersions, more specifically alkyd dispersions, can be substantially improved by utilizing resins derived from acidolysis reaction products of polyalkylene terephthalates and polyalkylene naphthalates. According to this invention, polymer dispersions can be produced from low acid value polymers and yet have good water dispersibility. When an aqueous coating composition is formulated using the dispersion of this invention, a final coating is formed that has good hydrolytic stability, and when blended with a latex, exhibits improved gloss and wet adhesion.

Abstract: The present invention is a novel gel-phase colorant dispersion comprising (a) a gel-phase colorant comprising the reaction product of (1) a reactive material component, (2) a reactive colorant, and (3) a crosslinker having reactive groups capable of forming a bond with the reactive material component and the reactive colorant; and (b) a dispersion medium, wherein the dispersion medium can be an aqueous or non-aqueous-based dispersion. The gel-phase colorant dispersion of this invention can then be mixed or blended with typical coating materials.
