Abstract:
1. An adhesive composition comprising (A) a polyimide resin having phenolic hydroxyl groups on its polymer skeleton and containing a diorganopolysiloxane linkage having vinyl groups as organic substituent groups on the backbone obtained by reacting a tetracarboxylic acid dianhydride selected from the group consisting of the following compounds: with a diamine compound comprising a diaminopolysiloxane, in which vinyl groups account for at least 5 mol % of the entirety of organic groups bonded to silicon atoms, represented by the formula (1): wherein R 1 is a divalent organic group of 3 to 9 carbon atoms, R 2 to R 6 each are a substituted or unsubstituted monovalent hydrocarbon group of 1 to 8 carbon atom, exclusive of vinyl, n is 0 or an integer of at least 1, m is an integer of at least 1, and the sum of n+m is an integer of 1 to 100, and a diamine of the formula (2): wherein R 7 is independently hydrogen, a halogen atom or a substituted or unsubstituted monovalent hydrocarbon group of 1 to 8 carbon atoms, (B) an epoxy resin, and (C) an epoxy resin curing catalyst.
