Abstract:
A polymerizable composition for an optical material according to the present invention, including: a monomer mixture (A) including a polymerizable monomer having a (meth) acrylic group, a photochromic compound (B) which is at least one selected from compounds represented by Formulae (1) and (2); and an ultraviolet absorbing agent (C) which is at least one selected from compounds represented by Formulae (a) to (c).

Claim (Index 8):
A method of manufacturing a plastic lens, comprising:\n a step of collectively mixing a monomer mixture (A) including a polymerizable monomer having a (meth)acrylic group, a photochromic compound (B) which is at least one selected from compounds represented by Formulae (1) and (2), and an ultraviolet absorbing agent (C) which is at least one selected from the compounds represented by Formulae (a) to (c) to prepare a polymerizable composition for an optical material; and a step of performing cast polymerization on the polymerizable composition for an optical material to form a lens substrate,\n PC-L-Chain\u2003\u2003(1) \n PC-L-Chain-L\u2032-PC\u2032\u2003\u2003(2) \n wherein in Formula (1) or (2), PC and PC\u2032 represent monovalent groups derived from compounds of Formulae (3) to (6), and PC and PC\u2032 may be identical to or different from each other, in Formulae (3) to (6), R 1  to R 18  represent hydrogen, a halogen atom, a carboxyl group, an acetyl group, a formyl group, an optionally substituted C1 to C20 aliphatic group, an optionally substituted C3 to C20 alicyclic group, and an optionally substituted C6 to C20 aromatic organic group, and may be identical to or different from each other, the aliphatic group, the alicyclic group, or the aromatic organic group may contain an oxygen atom and a nitrogen atom, and any one group included in the compounds represented by Formulae (3) to (6) is bonded to L or L\u2032 which is a divalent organic group; in Formula (1) or (2), L and L\u2032 each represent a divalent organic group including one or more selected from an oxyethylene chain, an oxypropylene chain, a (thio)ester group, and a (thio)amide group, and in Formula (1) or (2), Chain represents a monovalent or divalent organic group including one or more selected from a polysiloxane chain and a polyoxyalkylene chain; in Formula (a), R 1  and R 2  each represent a C1 to C8 alkyl group or a halogen atom and may be identical to or different from each other, a plurality of R 1 's existing together or a plurality of R 2 's existing together may be identical to or different from each other, and m represents an integer of 0 to 3, n represents an integer of 0 to 3, p represents an integer of 0 or 1, and R 3  represents a linear or branched C1 to C15 hydrocarbon group including an ester bond; in Formula (b), Z 1  and Z 2  may be identical to or different from each other, and represent a C1 to C6 alkyl group and a C1 to C6 alkoxy group; in Formula (c), Z 3  represents an optionally substituted C6 to C20 aromatic organic group and an optionally substituted C5 to C20 alicyclic group, and Z 4  and Z 5  may be identical to or different from each other and represent a C1 to C6 alkyl group and a C1 to C6 alkoxy group.
