Photosensitive resin composition, photosensitive dry film, and pattern forming process
A photosensitive resin composition comprising (A) a silicone resin containing an epoxy and/or phenolic hydroxyl group, (B) a photoacid generator, and (C) a cure promoter selected from diazabicycloundecene, diazabicyclononene, an organic salt of diazabicycloundecene derivative, and an organic salt of diazabicyclononene derivative is shelf stable. A photosensitive resin coating obtained therefrom may be processed to form a fine size pattern. The resin coating has improved film properties including chemical resistance, adhesion to substrates, mechanical properties, electric insulation, and copper migration resistance, and is thus fully reliable as an insulating protective film.
