PURPOSE:To obtain the titled composition having excellent film-forming property even without using a solvent and curable at a low temperature in a short time to give a cured product having excellent heat-resistance, etc., by compounding a polymaleimide oligomer, a butadiene polymer and other electron radiation reactive compound. CONSTITUTION:The objective composition can be produced by compounding (A) a polymaleimide oligomer [e.g. poly(methylenephenylene)polymaleimide], (B) a butadiene polymer (derivative) (e.g. 1,2-polybutadiene) and (C) a compound containing electron radiation reactive group other than the components A and B (e.g. unsaturated polyester). The composition is preferably coated or printed on a substrate and cured by electron radiation at an acceleration voltage of 150-300KV and dose of 3-3Mrad. |
