Abstract:
A polymerizable composition for an optical material of the present invention includes a compound (A) represented by General Formula (1) including two or more allyloxycarbonyl groups; an ultraviolet absorbing agent (B) represented by General Formula (i); at least one kind of radical polymerization initiator (C) selected from the group consisting of a peroxyketal-based radical polymerization initiator, a peroxymonocarbonate-based radical polymerization initiator, and a peroxyester-based radical polymerization initiator; at least one kind of dye (D) selected from an anthraquinone-based dye, a perinone-based dye, a monoazo-based dye, a diazo-based dye, and a phthalocyanine-based dye.
