INK CHANNEL WALL CONSTITUTIONAL COMPOSITION, INKJET RECORDING HEAD USING IT, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inkjet recording head which eliminates generation of a foreign substance that projects at an edge of an orifice, and which enables stable ink ejection by suppressing exfoliation of an ink channel wall even when the ink channel wall width reduces. SOLUTION: At least a part of the ink channel wall of the inkjet recording head is constituted of a polymerized cured substance of an ink channel wall constitutional composition that includes an epoxy resin, an alcohol system solvent and a cationic polymerization initiator of the structure shown by formula (I).
