NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION AND PRODUCTION OF RESIST IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a negative photosensitive resin compsn. excellent in storage stability and to provide a production method of a resist image by using this negative photosensitive resin compsn. SOLUTION: This compsn. contains a resin soluble with an alkali soln., an acid producing agent and an amino resin. The amt. of the amino resin is 1 to 3 pts.wt. to 100 pts.wt. of the resin soluble with an alkali soln. This negative photosensitive resin compsn. is applied on a substrate, dried, exposed to light or irradiated with active rays, heated and developed with an alkali soln.
