  • Waterborne acrylic coating compositions
    Patent number: 9221993
    Abstract: A waterborne coating composition includes latex particles and a crosslinker. The latex particles can be prepared from a mixture of reactants including: (a) a monomer represented by formula (I): where R1 is a hydrogen or methyl group and R2 is a hydrogen, alkyl, or aryl group; (b) a multi-ethylenically unsaturated monomer; and (c) a mono-ethylenically unsaturated functional monomer different from in the monomer represented by formula (I), the mono-ethylenically unsaturated functional monomer having a functional group selected from a hydroxyl group, thiol group, group, or a mixture thereof, where R9 is a hydrogen, alkyl, or aryl group. A method of preparing waterborne coating compositions and substrates coated with the compositions are also disclosed.
    Type: Grant
