Title:
POLYMERIZABLE COMPOSITION FOR OPTICAL MEMBERS, OPTICAL MEMBER, AND COLORED OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2021/060563
Kind Code:
A1
Abstract:
This polymerizable composition for optical members contains: a polyiso (thio) cyanate compound (A) having at least one aromatic ring in each molecule; a polythiol compound (B) having at least three mercapto groups in each molecule; and an acidic phosphate ester compound (C). The acidic phosphate ester compound (C) content is 0.1–3.0 parts by mass relative to 100 parts by mass of the total polyiso (thio) cyanate compound (A) and polythiol compound (B). The polymerization catalyst content is no more than 0.006 parts by mass relative to 100 parts by mass of the total polyiso (thio) cyanate compound (A) and polythiol compound (B).
