<p>PURPOSE:To obtain the title composition which has excellent flexibility, adhesiveness, heat resistance and electrical properties and moderate cure rate, and can be used in screen printing, by mixing an epoxy resin, an imidazole compound, and a long-chain dibasic acid anhydride. CONSTITUTION:100 pts.wt. epoxy resin (A) is mixed with 1-15pts.wt. imidazole compound (B) selected from among 2-ethyl-4-methylimidazole, 1-cyanoethyl-2- ethyl-4-methylimidazole, 2,4-diamino-6-[2-methylimidazolyl-(1)]-ethyl-s-triazine, and a 2,4-diamino-6-[ 2-ethyl-4-methylimidazolyl-(1) ]-ethyl-s-triazine/isocyanuric acid adduct, and a long-chain dibasic acid anhydride (C) comprising a 12-22C intermolecular polyacid polyanhydride of any one of formulas I-IV (wherein n is 3-10) in an amount of 0.05-0.9 equivalent based on one epoxy equivalent of component A. This mixture is kneaded so as to provide a particle size of <=10mum.</p> |
