Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. 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. 2. The optical material composition according to claim 1 , wherein the acrylate-based material further comprises an acrylate-based oligomer. 3. The optical material composition according to claim 1 , wherein the amount of component (b) is about 0.01% to about 6% of the total weight of the composition; and the amount of component (c) is about 0.01% to about 10% of the total weight of the composition. 4. The optical material composition according to claim 1 , further comprising (d) an anti-yellowing aid, selected from the group consisting of a thiol compound, a phenol compound, and a combination thereof. 5. The optical material composition according to claim 4 , wherein the amount of component (d) is about 0% to about 8% of the total weight of the composition. 6. The optical material composition according to claim 1 , wherein the composition is applied to a manufacturing process for a wafer level camera. 7. A wafer level camera lens, formed by the optical material composition according to claim 1 .
