Adducts of an epoxy resin and a compound containing at least one aromatic hydroxyl group and at least one polymerizable ethylenically unsaturated group per molecule are prepared which are optionally reacted with water, a secondary amine or a phenol which product is copolymerized with a polymerizable monoethylenically unsaturated carboxylic acid and a polymerizable monoethylenically unsaturated compound free of carboxylic acid groups. This product is rendered water miscible by reaction with a primary, secondary or tertiary amine or an alkali metal hydroxide, carbonate or bicarbonate. This product can then be cured with any suitable curing agent such as phenol/aldehyde compounds, urea/aldehyde compounds and melamine/aldehyde compounds and blocked isocyanates.
制备环氧树脂和一种每分子含有至少一个芳香羟基和至少一个可聚合乙烯不饱和基团的化合物的加合物,该加合物可选择与水、仲胺或苯酚反应,其产物与一种可聚合单乙烯不饱和羧酸和一种不含羧酸基团的可聚合单乙烯不饱和化合物共聚。通过与伯胺、仲胺或叔胺或碱金属氢氧化物、碳酸盐或碳酸氢盐反应,使该产品与水混溶。然后,可使用任何合适的固化剂(如苯酚/甲醛化合物、脲/甲醛化合物、三聚氰胺/甲醛化合物和封端异氰酸酯)对该产品进行固化。
