    摘要: The present invention is a coating composition having good scratch resistance and a method for improving the scratch resistance of a coating composition. The coating composition comprises

    (A) a film forming binder system containing a crosslinkable resin and optionally a crosslinking agent for the crosslinkable resin;
    (B) substantially colorless carbide or inorganic microparticles, range in size from about 1 to 1000 nanometers prior to incorporation in the coating composition, and the microparticles are reactive with the crosslinkable portion of the film forming binder system;
    (C) a solvent system for the crosslinkable resin, optional crosslinking agent, and microparticles,
    wherein the crosslinkable resin is present in an amount from about 10 to about 80% by weight and the inorganic microparticles are present in an amount from 0.1 to 60.0 % by weight based on the sum of the weights of the crosslinkable resin, the optional crosslinking agent, and the inorganic microparticles.

    摘要: A curable coating composition is described comprising two components that are reactive with one another upon curing to form urethane linkages. The composition further comprises a third component that includes one or more epoxide groups. Coatings prepared with this coating composition can be cured and coated with additional coating(s), providing good intercoat adhesion to the subsequent coating.

    摘要: Polyester polymers having pendant carbamate groups are disclosed. The polymers are prepared by:

    (a) reacting a hydroxyalkyl cyclic carbonate with ammonia, ammonium hydroxide, or a primary amine to form a dihydric alcohol having a carbamate group appended thereto,
    (b) reacting the dihydric alcohol from (a) and a cyclic anhydride to form a half-ester diacid having a carbamate group appended thereto, and
    (c) reacting a mixture comprising the half-ester diacid from step (b) and a polyol to form a polyester having carbamate groups appended thereto.
