A resin composition curable through a Michael reaction between (a) a component having a plurality of α,β-unsaturated carbonyl groups and (b) a component having a plurality of activated methylene, activated methyne or hydroxyl groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of an epoxy compound independently added to the composition or covalently attached to either component (a) or component (b).
本发明公开了一种可通过(a)具有多个α,β-不饱和羰基的组分和(b)具有多个活化亚甲基、活化甲基或羟基的组分之间的迈克尔反应固化的
树脂组合物。该固化反应是在一种独立添加到组合物中或共价连接到组分(a)或组分(b)上的环氧化合物存在下,用季
