PHOTOCURABLE AND THERMOCURABLE RESIN COMPOSITION, AND DRY FILM SOLDER RESIST

摘要

The present invention relates to a photocurable and thermocurable resin composition that shows improved alkali developability and is capable of providing a dry film solder resist having good heat resistance and dimensional stability, and to a dry film solder resist. The resin composition may comprise: an acid-modified oligomer having a carboxyl group (-COOH) and a photocurable functional group; a photopolymerizable monomer having an epoxy acrylate group of 3 or more functions bonded to a nitrogen-containing heteroring, and a compound configured with a functional group having a carboxyl group bonded to one expoxy acrylate group or more; a thermocurable binder having a thermocurable functional group; and a photoinitiator.
