ABSTRACT:
Positive photosensitive insulating resin compositions of the invention contain at least (A) an alkali soluble resin having a phenolic hydroxyl group, (B) a compound having a quinonediazido group, (C) crosslinked fine particles, (D) a compound containing at least two alkyletherified amino groups in the molecule, and (F) a solvent. The resin compositions have excellent resolution, electrical insulating properties and thermal shock properties. Cured products of the invention are obtained by curing these resin compositions, and they show good adhesive properties.
