Plastic lens composition, plastic lens, and process for producing the plastic lens

摘要

A composition for plastic lenses having a viscosity suitable for application to plastic lens materials and other optical materials and capable of giving a cured material having a relatively high refractive index and a low specific gravity, a plastic lens obtained by curing the composition, and a process for producing the plastic lens. A specific dicarboxylic acid component and a specific diol component are employed and the ratio of the components is adjusted to provide the composition for plastic lenses.
