Abstract
The present invention relates to a photo-curable and thermo-curable resin composition that can provide a dry film solder resist having a higher glass transition temperature and improved heat resistance reliability, and the dry film solder resist. Said resin composition may include an acid-modified oligomer including an iminocarbonate-based compound having a carboxy group (—COOH) and a photo-curable unsaturated functional group, a photo-polymerizable monomer having two or more photo-curable unsaturated functional groups, a thermo-curable binder having a thermo-curable functional group, and a photo-initiator.
