| titleOfInvention | Plastic optical material and production process thereof |
| abstract | Disclosed herein are plastic optical materials having properties that rays in a specific visible range are absorbed, being low in specific gravity and easy to conduct processing or machining, and having excellent glare-proofness. One of the plastic optical material comprises an acrylic polymer containing a specific phosphate group represented by the formula PO(OH) n - (n being 1 or 2) of 0.5-60%, and a metal ion component comprising a neodymium ion of 0.04-10 parts based on 100 parts of the acrylic polymer, and has properties that rays in a wavelength range about 580 nm are absorbed. Another plastic optical material comprises 100 parts of the same acrylic polymer, and 0.1-12 parts of a metal ion component composed of a manganese ion in a predominant amount and a neodymium ion, and has properties that rays in wavelength ranges of 400-500 nm and 555-605 nm are absorbed with high efficiency. n This plastic optical material is particularly suitable for use in plastic lenses for sunglasses. n A production process of the material is also disclosed which comprises the step of polymerizing a monomer mixture composed of a specific phosphate group-containing monomer and at least one copolymerizable monomer in the presence of at least one metallic compound of the desired kind and proportion. |
