Epoxy group-containing resin compositions

摘要

An epoxy group-containing thermosetting resin composition comprising (A) a copolymer obtained from (a) at least one member selected from an unsaturated carboxylic acid and an unsaturated carboxylic acid anhydride, (b) an epoxy group-containing unsaturated compound, (c) a monoolefin unsaturated compound, and (d) a conjugated diolefin unsaturated compound, and (B) an organic solvent for dissolving the above copolymer. There is also provided epoxy-group containing radiation sensitive resin composition which contains a component (A) obtained from (a), (b) and (c) and optionally (d), (C) a polymerizable compound having at least one ethylenically unsaturated double bond, and (D) a photopolymerization initiator. These epoxy-group containing thermosetting resin compositions are excellent in storage stability.
