[0244] (Production of adhesive for circuit connection)

[0245] In terms of solid mass ratio, thermoplastic resin, radical polymerizable compound and radical polymerization initiator, and boron-containing complex or amine compound are blended as shown in Table 1, and the adhesive component (adhesive for circuit connection 1.5% by volume of conductive particles was blended and dispersed based on the total volume of components other than the conductive particles to obtain an adhesive for circuit connection. The obtained adhesive for circuit connection was coated on a fluororesin film with a thickness of 80 μm using a coating device, and dried by hot air at 70° C. for 10 minutes to obtain a film-shaped circuit connection adhesive with an adhesive layer thickness of 20 μm. Adhesive.

Abstract

An adhesive composition which contains (a) a thermoplastic resin, (b) a radically polymerizable compound, (c) a radical polymerization initiator and (d) a complex containing boron, and wherein (d) the complex containing boron is a compound represented by general formula (A). (In formula (A), each of R1, R2 and R3 independently represents a hydrogen atom, an alkyl group having 1-18 carbon atoms or an aryl group; and each of R4, R5 and R6 independently represents a hydrogen atom or a specific organic group.)

Description

technical field [0001] The present invention relates to an adhesive composition and a bonded structure. Background technique [0002] In semiconductor elements and liquid crystal display elements, various adhesives have been used conventionally in order to bond various members in the elements. Requirements for adhesives, represented by adhesiveness, involve various aspects such as heat resistance and reliability under high temperature and high humidity conditions. The above-mentioned adhesive is used for the connection between liquid crystal display element and TCP (or COF), the connection between FPC and TCP (or COF), the connection between TCP (or COF) and printed wiring board, the connection between FPC and printed wiring board, etc. . In addition, the above-mentioned adhesive is also used when mounting a semiconductor element on a substrate. [0003] As the adherend for bonding, use a printed wiring board, or polyimide resin, polyethylene terephthalate (PET), polycarb...
