Abstract: [Problem] To provide a positive-type photosensitive resin composition that is produced with novolac resin and has good mechanical properties and high storage stability.

Abstract: The present invention provides a photosensitive resin composition comprising (a) an alkali-soluble resin, (b) a silicon compound having a secondary aromatic amino group and an alkoxy group, and (c) at least one selected from a photopolymerization initiator, a photo acid generator and a photo base generator. According to the present invention, it is possible to obtain a photosensitive resin composition which remarkably enhances the adhesion property with a substrate after curing without deteriorating storage stability of a solution, and does not cause peeling of a fine pattern even upon development.

Abstract: The present invention relates to a positive photosensitive resin precursor composition which exhibits good storage stability after exposure.
