  The invention provides epoxy and oxetane compositions including the novel acyloxy and N-acyl curing agents described herein. Use of invention curing agents result in cured adhesive compositions with remarkably increased adhesion and reduced hydrophilicity when compared to resins cured with other types of curing agents. Furthermore, the curatives of this invention do not interfere with free-radical cure and are thus suited for use in hybrid cure thermoset compositions.

  该发明提供了包括新型酰氧基和N-酰基固化剂的环氧树脂和氧环烷组合物。使用该发明的固化剂可使胶粘剂组合物固化后的粘附性大大增加，并且与用其他类型的固化剂固化的树脂相比，其亲水性减少。此外，该发明的固化剂不会干扰自由基固化，因此适用于混合固化热固性组合物的使用。

• Aqueous coating compositions

  Aqueous coating compositions include an anionic species-scavenging system. The scavenging system includes an aqueous dispersion of water-insoluble, weak base-functional polymer particles. The particles are polymerized from monomer including a weak base-functional monomer such as 2-(diethylamino)ethyl methacrylate or 2-(t-butylamino)-ethyl methacrylate. A two stage process may be employed to prepare the particles and 2-(dimethylamino)-ethyl methacrylate may be included only in the initial stage. Alternatively, a single stage process may be employed using 2-(t-butylamino)methacrylate. The system also includes a volatile base such as ammonia to maintain the pH of the composition above the pKa of the weak base prior to and during application of the composition. As the volatile base is lost, the weak base is protonated and forms ion pairs with anionic species such as anionic surfactant. The compositions form coatings having good water resistance, and may be used as paints, paper coatings, caulking materials, adhesives, binders for non-woven products and for floor polishes and printing inks.

  水性涂料组合物包括阴离子物种清除系统。清除系统包括不溶于水的弱碱功能聚合物颗粒的水性分散体。这些微粒由单体聚合而成，单体包括弱碱官能团单体，如 2-(二乙基氨基)乙基甲基丙烯酸酯或 2-(叔丁基氨基)-乙基甲基丙烯酸酯。制备颗粒时可采用两阶段工艺，2-(二甲基氨基)-乙基甲基丙烯酸酯可仅用于初始阶段。另外，也可以使用 2-（叔丁氨基）甲基丙烯酸乙酯进行单阶段制备。该系统还包括挥发性碱（如氨），以便在使用组合物之前和使用期间将组合物的 pH 值保持在弱碱的 pKa 以上。随着挥发性碱的流失，弱碱被质子化，并与阴离子物质（如阴离子表面活性剂）形成离子对。这种组合物形成的涂料具有良好的耐水性，可用作油漆、纸张涂料、填缝剂、粘合剂、无纺布产品粘合剂以及地板抛光剂和印刷油墨。

  A paint composition comprising cationic latex polymeric binder, pigment and selective cationic pigment dispersant is disclosed. The paint compositions, which demonstrate the advantages of a water-­based system, also exhibit excellent stain blocking, corrosion resistance, water sensitivity resistance and adhesion to wood and alkyd surfaces which are competitive in performance with conventional solvent based alkyd primers.
