PURPOSE: To provide a photosensitive resin compsn. developable with an aq. soln. and excellent in flame retarding property because of an added flame retardant causing no problem on safety, environment, etc., and to provide a printed circuit board using the resin compsn. CONSTITUTION: An acrylate which cures when irradiated with light and a photopolymn. initiator are blended with condensed phosphoric acid amide. At least one among epoxy resin, epoxy acrylate having an epoxy residue and carboxyl group-contg. epoxy acrylate having an epoxy residue and an epoxy resin curing agent are further incorporated. |
