    摘要： A coating composition includes: a polymer prepared from a reaction mixture including: a hydroxyl functional prepolymer comprising a reaction product of a prepolymer mixture and a non-aromatic anhydride. The polymer includes at least two functional groups selected from hydroxyl groups, carboxyl groups and combinations thereof. The polymer includes 10-40 weight % of structural units derived from benzoic acid or substituted benzoic acid and greater than 15 weight % of structural units derived from a polyol having at least three hydroxyl groups based on the total weight of the polymer. A substrate at least partially coated with a coating composition and a method of preparing a coating composition are also disclosed.

    摘要： 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.

    摘要： Disclosed is a polyester prepared from a mixture of reactants including: a) an aromatic monoacid, where the aromatic monoacid includes from 25 to 60 weight % based on the total weight of reactants; b) a polyacid, where the polyacid includes less than 90 mole % isophthalic acid; and c) a polyol having at least 3 hydroxyl groups. The mixture of reactants is substantially free of a non-aromatic monoacid, and said polyester has a dynamic viscosity of greater than 15,000 centipoise at 40° C. as measured by a Physica MCR 301 rheometer with 25 mm parallel plate and 0.1 mm gap as a function of increasing shear rate (0.1 to 10 s−1), and an acid value of less than 15 mg KOH/g. The polyacid can also be an aliphatic polyacid. Coatings comprising the same and substrates coated at least in part with such coatings are also disclosed.
