  Disclosed herein is a silicone-modified polyimide resin composition of solvent free type. The composition is suitable for use as an adhesive and a coating material which are capable of hardening upon irradiation with ultraviolet rays and/or visible rays. Also, it is saved from drooling even in the case of light filling with an inorganic compound and it is saved from bubble entrapment and nonuniformity at the time of application with heavy filling. It further exhibits good moldability due to its thixotropic properties. Moreover, it exhibits improved adhesion to polyolefin resins without impairing the past properties. Finally, it gives rise to a cured product which is not excessively hard, with a low elastic modulus, despite filling with an inorganic compound. The composition of the present invention includes components (A) to (B) listed below and is characterized by being fluid at 25° C. and free of solvent: (A) silicone-modified polyimide resin; (B) polymerizable compound; (C) polymerization initiator, (D) hydrophobic fumed silica; and (E) adhesion auxiliary agent.

  本文公开了一种无溶剂型硅改性聚酰亚胺树脂组合物。该组合物适合用作粘合剂和涂层材料，在紫外线和/或可见光照射下能够硬化。此外，即使在轻度填充无机化合物的情况下，它也不会流口水，而在重度填充时，它也不会夹带气泡和不均匀。由于其触变性能，它还具有良好的成型性。此外，它还能改善与聚烯烃树脂的粘附性，同时不影响其以往的特性。最后，尽管填充了无机化合物，固化后的产品也不会过硬，弹性模量较低。本发明的组合物包括下列成分（A）至（B），其特点是在 25°C 时为流动性，不含溶剂： (A) 硅改性聚酰亚胺树脂； (B) 可聚合化合物 (C) 聚合引发剂 (D) 疏水性气相法二氧化硅；以及 (E) 粘合辅助剂。
