RADIATION-SENSITIVE RESIN COMPOSITION, SPACER FOR LIQUID CRYSTAL DISPLAY ELEMENT, PROTECTIVE FILM, AND METHOD FOR PRODUCING SPACER FOR LIQUID CRYSTAL DISPLAY ELEMENT OR PROTECTIVE FILM

摘要

Disclosed is a radiation-sensitive resin composition containing a copolymer[A]of an unsaturated carboxylic acid and/or unsaturated carboxylic acid anhydride and an unsaturated compound different from them, a polymerizable unsaturated compound[B], a radiation-sensitive polymerization initiator[C]and a nitroxyl compound[D]such as bis(1-oxyl-2,2,6,6-tetramethylpiperidin-4-yl)sebacate. This radiation-sensitive resin composition has excellent resolution performance and enables to form a fine pattern.
