摘要:
An epoxy resin composition comprising an epoxy resin, either 2-vinyl-4,6-diamino-s-triazine or 2-vinyl-4,6-diamino--s-triazine/isocyanuric acid adduct, and at least one compound selected from dicyanidamide, polyvinyl-p-phenol and specific imidazole compounds is useful, for example, in inks, insulating paints and adhesives for printed circuit base boards and in copper-clad laminated boards.
摘要:
Disclosed is a 2-substituted-4, 6-diamino-s-triazins/ isocyanuric acid adduct represented by the following formula: wherein R stands for an alkyl group having 2 to 20 carbon atoms, an unsubstituted or cyano group-substituted aryl group, or a group of the formula R 1 -CH 2 CH 2 - in which R' stands for an alkoxy group having up to 20 carbon atoms, an acyloxy group, an amino group, an N-substituted amino group, a benzotriazolyl group or a 2-alkylimidazolyl-(4)-dithiocarbonyl group, or by the following formula: wherein R 2 -(CH 2 ) m -(X) p -(CH 2 ) m - where
m is 1 or 2 p is 0 or 1 and X is imino or phenylene.
When this adduct is used for curing a polyepoxy resin, a cured product having good heat resistance, insulating property and adhesion and an excellent migration-preventing effect is formed.
