Abstract
The present invention relates to a photo-curable and thermo-curable resin composition and a dry film solder resist making it possible to provide the dry film solder resist having superior heat-resistance and dimensional stability while exhibiting improved alkali developing properties. The resin composition may comprise an acid-modified oligomer having carboxyl group (—COOH) and photo-curable functional group; a photo-polymerizable monomer comprising a compound having a structure that three or more functional epoxy-acrylate groups are bonded to a heterocyclic structure containing nitrogen, and a functional group having carboxyl group is bonded to at least one epoxy-acrylate group; a thermo-curable binder having thermo-curable functional group; and a photo-initiator.
