    • PROBLEM TO BE SOLVED: To provide an epoxy resin composition excellent in flexibility and flame retardancy, and to provide an epoxy resin varnish, a bonding sheet and a cover-lay film using the composition.SOLUTION: The epoxy resin composition comprises (a) an epoxy resin, (b) a curing agent and (c) a phenolic hydroxy group-containing aromatic polyamide-polybutadiene-acrylonitrile copolymer. In the composition: the (a) component is a trishydroxyphenylmethane type epoxy resin; the (b) component is composed of 10(2,5-dihydroxyphenyl)-10H-9-oxa-10-phosphaphenanthrene-10-oxide only; phenolic hydroxy groups in the (b) component are included by 0.5 mol or more with respect to 1.0 mol of epoxy groups in the (a) component; and the compounding rate of the (c) component is 5 to 300 pts.mass with respect to 100 pts.mass of the total of the (a) component and the (b) component.
    • 要解决的问题:提供柔性和阻燃性优异的环氧树脂组合物,并使用该组合物提供环氧树脂清漆,粘合片和覆盖膜。 环氧树脂组合物包含(a)环氧树脂,(b)固化剂和(c)含酚羟基的芳族聚酰胺 - 聚丁二烯 - 丙烯腈共聚物。 在组合物中:(a)组分是三羟基苯基甲烷型环氧树脂; (b)组分仅由10(2,5-二羟基苯基)-10H-9-氧杂-10-磷杂菲-10-氧化物组成; (b)成分中的酚羟基相对于(a)成分中的1.0摩尔环氧基包含0.5摩尔或更多; (c)成分的配合比例相对于(a)成分和(b)成分的总量的100个点,为5〜300个点。 版权所有(C)2013,JPO&INPIT
