Inkjet recording head and ink jet recording apparatus containing a fluorinated epoxy resin composition

摘要

A fluorine-containing epoxy resin composition comprising a fluorine-containing aromatic epoxy resin having in one molecule at least one perfluoroalkyl group having 6 to 12 carbon atoms and preferably at lest two epoxy groups, a cationic polymerization catalyst, and optionally a compatibilizing agent having an epoxy group and a fluoromethyl group is coated on discharge openings of an ink jet recording head, followed by exposure to activation energy ray in a given pattern form to form cured coatings with a desired pattern so that the discharge openings can be endowed with ink repellency. <IMAGE>
