Abstract:
PROBLEM TO BE SOLVED: To provide an epoxy resin curable composition having low coefficient of linear expansion without using a filler and excellent also in physical properties of tensile strength and elongation. SOLUTION: The epoxy resin curable composition uses a phenol compound having a benzoxazole structure represented by general formula (I) as a curing agent for epoxy resin or uses an epoxy compound having the above structure as the epoxy resin.

Abstract:
PROBLEM TO BE SOLVED: To provide a composite material having an epoxy resin adhesive layer at the interface of a polyimide layer and an epoxy resin layer. SOLUTION: The composite material is formed by laminating a layer (B) comprising a polyimide on a layer (A) comprising an epoxy resin curable composition containing a polyamide compound which has a structure having a phenolic hydroxyl group represented by the general formula (I) or the general formula (II). In the formulae (I) and (II), rings A and B are each a 6-18C arylene group or a 13-25C alkylidenediarylene group. COPYRIGHT: (C)2009,JPO&INPIT
