Patent ID: 7214454

Claim:
A positive photosensitive insulating resin composition comprising: (A) an alkali soluble resin having a phenolic hydroxyl group, (B) a compound having a quinonediazido group in an amount of from 10 to 50 parts by weight on the basis of 100 parts by weight of the alkali soluble resin having a phenolic hydroxyl group, (C) crosslinked fine particles which are obtained by copolymerizing a crosslinkable monomer having at least two unsaturated polymerizable groups with one or more different monomers, (D) a compound containing at least two alkyletherified amino groups in the molecule, and (F) a solvent, wherein the crosslinkable monomer having at least two unsaturated polymerizable groups is at least one monomer selected from the group consisting of divinylbenzene, diallylphthalate, ethylene glycol di(meth)acrylate, propylene glycol di(meth)acrylate, trimethylol propane tri(meth)acrylate, pentaerythritol tri(meth)acrylate, polyethylene glycol di(meth)acrylate and polypropylene glycol di(meth)acrylate.
