NEW ORGANIC PHOTOCHROMIC AND NON-PHOTOCHROMIC MATERIALS

摘要

The present invention relates to the photochromic and transparent organic refractive index of non-photochromic to be greater than 1.55, and these are from optical distortion. The polymerized organic material optionally contains photo-chromic colorant, dyestuff, chain-transferring agent, polymerization initiator or catalyst and hindered amine light stabilizer. The organic polymer material is suitable for forming spectacle lens, automobile and building window glass.
