IMIDE RESIN WITH HIGH REFRACTIVE INDEX, THERMOPLASTIC RESIN COMPOSITION FOR LENS USING SAME, AND LENS

摘要

Disclosed is a thermoplastic resin having high light transmittance, high refractive index and excellent moldability. The thermoplastic resin can be molded by a commonly used molding process, and is useful for reduction in lens weight or the like. Specifically disclosed is an imide resin of a specific structure, in particular, an imide resin containing a glutarimide unit and an acrylate or methacrylate unit. The imide resin has a high light transmittance and a high refractive index of not less than 1.53. This imide resin is a thermoplastic resin to which common molding processes can be applied, and thus can be suitably used as a lens material.
