Abstract
The present invention provides an optical material composition, including: (a) an acrylate-based material; (b) an anti-yellowing agent, selected from the group consisting of an inorganic phosphorus-containing acid, a phosphate and a combination thereof; and (c) an initiator. After being cured, the composition of the present invention has good transmittance, anti-yellowing performance and high-temperature resistance.
Claims7
An optical material composition, comprising the following components:
- (a) an acrylate-based material;
- (b) an anti-yellowing agent, selected from the group consisting of phosphoric acid, phosphate salt, phosphorous acid, hypophosphorous acid, hypophosphite salt, and a combination thereof;
- and
- (c) an initiator,
- wherein the amount of component (a) is about 70% to about 99.9% of the total weight of the composition, the acrylate-based material comprises an acrylate-based monomer, and the acrylate-based monomer comprises at least about 5% by weight of a multi-functional acrylate-based monomer.
