The present invention aims to provide a means by which a cured product to be obtained has a low dielectric loss tangent and higher heat resistance. Specifically, provided are an active ester compound represented by chemical formula (1):
(where in chemical formula (1), Ar1 is a substituted or unsubstituted first aromatic ring group, and each Ar2 is independently a substituted or unsubstituted second aromatic ring group, in which at least one of Ar1 and Ar2 has an unsaturated bond-containing substituent, and n is an integer of 2 or 3), a curable composition containing the active ester compound, and a cured product thereof.
本发明旨在提供一种方法,通过该方法获得的固化产品具有较低的介电损耗正切和较高的耐热性。具体而言,本发明提供了一种由
化学式(1)表示的活性酯化合物:
(其中,Ar1 是取代或未取代的第一芳环基团,每个 Ar2 独立地是取代或未取代的第二芳环基团,其中 Ar1 和 Ar2 中至少有一个具有含不饱和键的取代基,且 n 是 2 或 3 的整数)、含有该活性酯化合物的可固化组合物及其固化产物。
