PHOTOSENSITIVE RESIN HAVING IMPROVED DEVELOPING MARGIN AND ADHESIVE CHARACTERISTIC

摘要

PURPOSE: A photosensitive resin having a prominent development margin and adhesive characteristic is provided to improve the development margin and the adhesive characteristic by using a crosslinked bond between a monomer having active hydrogen and a silane coupling agent within a binder. CONSTITUTION: A photosensitive resin having a prominent development margin and adhesive characteristic includes a binder of 5 to 30 weight percent, a crosslinkable monomer of 5 to 30 weight percent, paints of 10 to 60 weight percent, a photopolymerization initiator of 0.5 to 5 weight percent, a solvent of 20 to 80 weight percent, and a silane coupling agent of 0.1 to 2 weight percent. The binder melts in alkali aqueous solution. The crosslinkable monomer is formed with two or more ethylene-based double bond. The silane coupling agent has one or more isocyanate base.
