Provided is a process for production of a cured molded article capable of readily producing a transparent and discoloration-free cured molded article that exhibits a low shrinkage ratio and an excellent heat resistance, abrasion resistance, and mold release behavior. Also provided is a cured molded article that is useful in a variety of applications, for example, as an optical member. The process for production of a cured molded article from a curable resin composition that comprises a condensable inorganic compound, a curable organic compound, and a curing agent is a process for production of a cured molded article including a first step composed of a step of thermally curing the curable resin composition at 80 to 200°C and/or a step of curing the curable resin composition by exposure to active-energy radiation, and a second step of subjecting the cured material obtained in the first step to a thermal cure at above 200°C but not more than 500°C.
本发明提供了一种固化成型品的生产工艺,该工艺能够轻松生产出透明且无变色的固化成型品,该成型品具有较低的收缩率和出色的耐热性、耐磨性和脱模性。此外,还提供了一种固化成型品,可用于多种用途,例如光学部件。由可凝结无机化合物、可固化有机化合物和固化剂组成的可固化树脂组合物生产固化成型品的工艺是一种生产固化成型品的工艺,包括第一步,在 80 至 200°C 的温度下对可固化树脂组合物进行热固化和/或通过暴露于活性能量辐射对可固化树脂组合物进行固化;第二步,将第一步中获得的固化材料在 200°C 以上但不超过 500°C 的温度下进行热固化。
