摘要

An active energy-ray-curable resin composition of a cation-polymerizable type for forming a wall of a flow path of an ink jet-head comprises 50 to 98.5 % by weight of an aromatic epoxy resin having a molecular weight of not less than 300, 1 to 10 % by weight of a silane coupling agent, and 0.5 to 5 % by weight of an active catalyst.
