  The present invention has its object to provide a curable composition, although having low viscosity itself, which gives a cured product, when being cured, which has wide range of elasticity, from hard to soft, which is excellent in weather resistance and heat resistance, and the hardness and brittleness (characteristic to epoxy resins) of which have been improved to have rubber elasticity, and which has high adhesion strength and is transparent. The curable composition of the present invention comprises a vinyl polymer containing at least one crosslinkable silyl group on average and an epoxy resin. When being used for adhering or sealing a transparent material such as glass, polycarbonates, and acrylic resins, the curable composition of the invention is usable for treatment with sufficiently retaining the transparency, which is an aesthetic characteristic.

  本发明的目的是提供一种固化组合物，虽然其本身的粘度较低，但在固化时得到的固化物具有从硬到软的广泛弹性范围，具有优异的耐候性和耐热性，其硬度和脆性（环氧树脂的特征）已得到改善，具有橡胶弹性，并且具有高粘合强度和透明性。本发明的固化组合物包括平均含有至少一个可交联硅基的乙烯基聚合物和环氧树脂。本发明的可固化组合物在用于粘合或密封透明材料（如玻璃、聚碳酸酯和丙烯酸树脂）时，可在充分保持透明性这一美学特性的前提下进行处理。
