and
wherein R1 is alkyl or aryl, R2 and R4 are the same or different alkyl other than methyl and R3 is alkylene, vinylene or, in formula (B), a single bond, the ester having acceptable hydrolytic stability and a normal boiling point of from 160°C to 290°C.
由 Tg 大于 0°C 的水不溶性添加聚合物组成的水性涂料组合物含有至少一种式中的酯作为凝聚剂:
和
其中 R1 是烷基或芳基,R2 和 R4 是除甲基外相同或不同的烷基,R3 是亚烷基、亚乙烯基或在式 (B) 中为单键,酯具有可接受的水解稳定性和 160°C 至 290°C 的正常沸点。
