| 摘要 |
An ink jet recording head comprises an ink jetting nozzle and a peripheral area of the ink jetting nozzle, the peripheral area having been coated with a coating composition comprising a graft copolymer and a hardener, and having been hardened to provide a hardened coat layer, wherein the graft copolymer is obtained by polymerizing 15 to 70% by weight of a radical polymerizable fluorine-containing resin (a) having a radical polymerizable unsaturated bond through a urethane bond, 10 to 40% by weight of a radical polymerizable polysiloxane (b) having a radical polymerizable double bond on one end thereof represented by formula (1) or (2), and 15 to 75% by weight of a radical polymerizable monomer (c), each being based on the total weight of the radical polymerizable fluorine-containing resin (a), the radical polymerizable polysiloxane (b) and the radical polymerizable monomer (c).
