An adhesive pattern 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 as a member to be bonded to form a coating film; selectively exposing the coating film to an active energy ray through a photomask according to a predetermined pattern, thereafter removing an unexposed portion by development with an aqueous alkaline solution. Then, a sheet member as a joining member is pressed onto the adhesive pattern mentioned above, and the adhesive pattern is thermally cured to obtain a laminated structure.

Composition for forming adhesive pattern, laminated structure obtained by using same, and method of producing such laminated structure

Disclosed is a liquid ejecting recording head with improved operational reliability. A first coating resin layer of a liquid ejecting recording head, having a liquid flow duct and a liquid ejecting orifice, is formed of an oxetane resin composition that contains, as necessary components, an oxetane compound having at least one oxetanyl group in a molecule, and a cationic photopolymerization initiator.
