热固性粘接组合物、热固性粘接片材、其制造方法及增强柔性印刷布线板
Abstract:
本发明涉及热固性粘接组合物、热固性粘接片材、其制造方法及增强柔性印刷布线板。热固性粘接组合物，其含有丙烯酸系共聚物(A)、环氧树脂(B)和环氧树脂用固化剂(C)。丙烯酸系共聚物(A)是将不含环氧基的(甲基)丙烯酸酯单体(a)65～75质量％、丙烯腈单体(b)20～35质量％和含环氧基的(甲基)丙烯酸酯单体(c)1～10质量％共聚而成的。环氧树脂用固化剂为平均粒径0.5～15μm的有机酸二酰肼粒子。
Abstract(English):

Disclosed is a thermosetting adhesive composition comprising (A) an acrylic copolymer, (B) an epoxy resin, and (C) an epoxy resin curing agent. The acrylic copolymer (A) is obtained by copolymerizing 65 to 75% by mass of (a) a (meth)acrylic ester monomer containing no epoxy group, 20 to 35% by mass of (b) an acrylonitrile monomer, and 1 to 10% by mass of (c) a (meth)acrylic ester monomer containing an epoxy group. The epoxy resin curing agent comprises particles of an organic acid dihydrazide having an average particle diameter of 0.5 to 15 [mu]m.
