Abstract
Description
technical field
[0001] The present invention relates to a resin composition for optical materials, and further relates to optical materials such as plastic lenses, prisms, optical fibers, information recording substrates, and filters using the resin composition. Among them, the present invention is suitably used as a plastic lens. Background technique
[0002] In recent years, plastic materials have been widely used in various optical materials, especially eyeglass lenses, due to their light weight, high toughness, and easy dyeing. The physical properties required in optical materials, especially as eye lenses, include low specific gravity, high transparency, low yellowness, high heat resistance, and high strength, and the optical properties include high refractive index. and a high Abbe number. A high refractive index can make the lens thinner, and a high Abbe number can reduce the chromatic aberration of the lens, but as the refractive index increases, the Abbe number de...
