Abstract

The present invention provides a resist ink composition comprising a compound (a) having at least one oxetanyl group and at least one epoxy group within the same molecule and a compound (b) capable of initiating cationic polymerization under irradiation by an active energy ray and/or under heat. This resist ink composition has high photosensitivity and enables the final curing by a brief heating and the cured film exhibits good physical properties.
