Abstract
A photosensitive insulating resin composition capable of forming an interlayer insulating film, or planarized film, or surface protective film, or insulating film for high-density mount substrate excelling in properties, such as resolution, adherence, thermal impact, electrical insulation, patterning performance and elongation; a hardening product thereof; and a circuit board equipped with the hardening product. There is provided a positive photosensitive insulating resin composition comprising an alkali-soluble resin; a compound having a quinonediazido group; and crosslinked resin particles of a particulate copolymer whose 20 to 90 mol % constituent is derived from a hydroxylated and/or carboxylated monomer.
