COMPOSITION FOR FORMING ADHESIVE PATTERN, MULTILAYER STRUCTURE OBTAINED BY USING SAME, AND METHOD FOR PRODUCING SUCH MULTILAYER STRUCTURE

摘要

An adhesive pattern (4) is formed by applying a photocurable and thermosetting adhesive comprising as indispensable ingredients (A) a carboxyl group-containing photosensitive prepolymer having both a carboxyl group and an ethylenically unsaturated bond in its molecule and an acid value in the range of 30 to 160 mg KOH/g, (B) an epoxy resin, and (C) a photopolymerization initiator onto a surface of a substrate (1) as a member to be bonded to form a coating film; selectively exposing the coating film to an active energy ray through a photomask (3) according to a predetermined pattern, thereafter removing an unexposed portion by development with an aqueous alkaline solution. Then, a sheet member (5) as a joining member is pressed onto the adhesive pattern mentioned above, and the adhesive pattern is thermally cured to obtain a laminated structure.
