  • Aqueous polymer dispersions
    Patent number: 7129278
    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.

  • Ink composition using alkyd-stabilized acrylic dispersions
    Publication number: 20040044098
    Abstract: An ink composition comprising a pigment or pigment dispersion; and an alkyd-stabilized acrylic dispersion having a non-volatile materials content of greater than 70%; and an ink solvent. The alkyd-stabilized acrylic dispersion comprises an alkyd resin; at least one acrylic monomer suitable for free radical addition polymerization, wherein at least one acrylic monomer is hydroxy-functional; and a chain transfer agent.
