POLYVALENT HINDERED AMINE COMPOUND SUITABLE FOR OPTICAL MATERIAL, ITS PRODUCTION METHOD, NORBORNENE-BASED RESIN COMPOSITION, AND LIGHT GUIDE PLATE

摘要

PROBLEM TO BE SOLVED: To provide a high molecular weight hindered amine compound having excellent handleability without impairing the original optical transmittance of a resin for an optical material even when used for the stabilization of the resin.;SOLUTION: This hindered amine compound has an optical transmittance of ≥99% at 425 nm wavelength in a 10 wt% toluene solution and a molecular weight of 600 to 1,000, and is preferably represented by general formula (I). There are also provided a production method therefor, particularly that with a refining process, a norbornene-based resin composition containing the compound, and a light guide plate comprising the composition.;COPYRIGHT: (C)2005,JPO&NCIPI
