Document Type and Number:

WIPO Patent Application WO/2019/111969

Kind Code:

A1

Abstract:

This polymerizable composition for an optical material includes: (A) an allyl carbonate compound represented by general formula (1), including two or more allyloxycarbonyl groups; (B) a (meth)acrylate compound represented by general formula (2), including two or more (meth)acrylic groups; (C) at least one type of compound selected from the dyes below and a compound represented by general formulas (3)-(6); and (D) a polymerization initiator including at least a radical polymerization initiator (D1) and a radical polymerization initiator (D2); more than 0 wt% and no more than 30 wt% of the compound (A) and 70 wt% to less than 100 wt% of the compound (B) being included in a total of 100 wt% of the compound (A) and the compound (B), the radical residual ratio of the radical polymerization initiator (D1) after 5 hours at 50°C being 20% to less than 100%, and the radical residual ratio thereof after 5 hours at 70°C being 0% to less than 30%, and the radical residual ratio of the radical polymerization initiator (D2) after 5 hours at 70°C being 30% to less than 98%.
