用于可阴极沉积水性涂料组合物的粘合剂的水乳液，其包含(A) 98至50重量％的至少一种水溶性自交联阳离子树脂的乳液，所述水溶性自交联阳离子树脂在用无机或有机酸部分或全部中和后可被水稀释并且在1000个分子量单元中具有至少0.5个碱性氮原子和至少0.5的双键数； (B)2～50重量％的双键数为0.8以上的水不溶性自交联缩聚树脂或聚合树脂。任选地，水不溶性自交联树脂可包括碱性特征但不足以提供水溶性。即使在电沉积浴中常用的充分稀释的形式下，乳液也具有优异的稳定性，无需使用其他乳化剂。当用于涂料组合物中时，乳液提供具有良好粘合特性的膜，在相对低的温度和相对短的固化时间下固化，以提供具有优异的耐水性、耐化学品性和耐腐蚀性的膜。
Aqueous emulsions of binders for cathodically depositable aqueous coating compositions comprising emulsions of (A) 98 to 50 percent by weight of at least one water-soluble self-crosslinking cationic resin which is water-dilutable upon partial or total neutralization with an inorganic or organic acid and having at least 0.5 basic nitrogen atoms in 1000 molecular weight units and a double bond number of at least 0.5; and (B) 2 to 50 percent by weight of a water-insoluble self-crosslinking polycondensation resin or polymerization resin having a double bond number of at least 0.8. Optionally, the water-insoluble self-crosslinking resin can include basic character but insufficient to provide water solubility. The emulsions have excellent stability without use of other emulsifiers even in substantially diluted form usual for electrodeposition baths. The emulsions when used in coating compositions provide films which have good adhesion characteristics, cure at relatively low temperatures and relatively short curing times to provide films having excellent resistance to water, chemicals, and corrosion.
