ABSTRACT:
An adhesive for use in bonding finely processed parts such as parts of ink jet recording head has a composition which essentially contains: (A) a vinylester compound of an urethanated epoxy resin; (B) a partial vinylester compound of a multi-functional epoxy resin; (C) an acrylic reactive diluent; (D) a photopolymerization initiator; and(E) an epoxy cure agent. This adhesive is curable by ultraviolet irradiation or by application of heat, and does not flow or spread into areas where bonding is not necessary, so that finely processed parts are bonded with a high degree of precision of the bonding pattern.
