    摘要: An epoxy resin composition comprising an epoxy resin, a curing agent, and a copolymer mixture comprising a long-chain organopolysiloxane copolymer [I] and a short-chain organopolysiloxane copolymer [II] which are each prepared by the addition reaction of an alkenyl-containing epoxy resin with a long-chain or short-chain organopolysiloxane containing pendant phenyl groups at a weight ratio of [II] to [I] of 0.3 to 0.6 is disclosed. The epoxy resin composition exhibits excellent printability, crack resistance, and moldability properties.
