PURPOSE:To provide a precise liquid jet recording head having excellent durability, by using a specific resin composition in the preparation of the liquid jet recording head. CONSTITUTION:A liquid jet recording head is constituted by a method wherein the pattern exposure of active energy rays is applied to the layer comprising a resin composition on a substrate to form cured regions and uncured regions are removed to form liquid passages to the surface of the substrate. Said resin composition consists of (i) a graft copolymer obtained by adding a branched chain based on a structural unit occurring from (A) a hydroxyl group-containing acrylic monomer, (B) an amino or alkylamino group-containing acrylic monomer, (C) a carboxyl-containing acrylic or vinyl monomer, (D) N-vinyl pyrrolidone or a derivative thereof, (E) vinyl pyridine or a derivative thereof and (F) an acrylamide derivative represented by general formula I to a main chain based on a structural unit occurring from monomers of alkyl methacrylate, acrylonitrile and styrene and (ii) a resin obtained by esterifying a part of the epoxy groups present in an epoxy resin containing a compound having two or more of epoxy groups in the molecule thereof by unsaturated carboxylic acid. |
