POLYMERIZABLE COMPOSITION FOR OPTICAL MATERIAL

摘要

This polymerizable composition for an optical material contains: (A) at least one type of isocyanate having two or more isocyanato groups such as an aromatic isocyanate; (B) at least one type of alcohol having two or more hydroxyl groups; and (C) an acidic phosphoric acid ester represented by general formula (1). The percentage of secondary hydroxyl groups is at least 50% of the total number of moles of primary and secondary hydroxyl groups contained in the alcohol (B).
