Plastic optical material |
摘要 |
Disclosed herein is a plastic optical material, which has excellent glare-proofness and transparency and is low in the degree of coloring. The plastic optical material of the invention comprises a polymer containing a phosphate group and a trivalent neodymium ion therein, wherein the polymer further contains at least one metal ion selected from the group consisting of a trivalent praseodymium ion and a trivalent holmium ion. The phosphate group may preferably be chemically bonded to a molecular structure constituting the polymer. In particularly, the polymer may preferably be a copolymer obtained by copolymerizing a monomer represented by the following formula I: PO(OH)nR3-nwherein R means a polymerizable functional group represented by the formula: <IMAGE> in which X denotes a hydrogen atom or a methyl group, and m is an integer of 0-5, and n is 1 or 2, and at least one monomer copolymerizable therewith.
