  Water-dilutable polyurethane/acrylic copolymers which may be either completely nonionically stabilized or partially nonionically and partially anionically stabilized comprise the reaction product of an ethylenically terminated polyurethane macromonomer containing poly(oxyalkylene) segments and one or more ethylenically unsaturated monomers selected from acrylic acid, methacrylic acid, fumaric acid, styrene, vinyltoluene, and alkyl and hydroxyalkyl esters of acrylic, methacrylic, and furamic acids. The copolymers are useful as principal resins and as pigment grind resins in water-borne automotive base coat paint formulations.

  可用水稀释的聚氨酯/丙烯酸共聚物可以是完全非离子稳定的，也可以是部分非离子稳定和部分阴离子稳定的，由含有聚（氧烷基）段的乙烯基端聚氨酯大单体和一种或多种乙烯基不饱和单体的反应产物组成，这些单体选自丙烯酸、甲基丙烯酸、富马酸、苯乙烯、乙烯基甲苯以及丙烯酸、甲基丙烯酸和富马酸的烷基酯和羟烷基酯。这些共聚物可用作水性汽车底漆配方中的主树脂和颜料研磨树脂。

  Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a waterborne basecoat containing a first hydroxy-functional resin, a first crosslinking agent, a first catalyst, and an organic solvent; and a solventborne topcoat containing a second hydroxy-functional resin, a second crosslinking agent, a second catalyst, and water, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.
