PURPOSE: To provide a composition which satisfies various performances required as an interlayer insulating film, such as adhesion, surface hardness, transparency, heat-, light- and solvent resistances and is used for forming an interlayer insulating film by a low-cost ink jet system. CONSTITUTION: The composition comprises (A) a copolymer of (a1) an unsaturated carboxylic acid and/or an unsaturated carboxylic acid anhydride, (a2) an epoxy-containing unsaturated compound and (a3) other olefinic unsaturated compounds, (B) a 1,2-quinonediazide compound and (C) a solvent having >=180°C boiling point under ordinary pressure.
