    • Disclosed herein are plastic optical materials, which have performance characteristics that rays in a specific wavelength region are absorbed with high efficiency, can attain desired optical properties such as good glare-proofness and moreover has low water absorption property, and a production process thereof.
      The plastic optical materials comprise an acrylic resin, and a phosphate group, an amide group and a metal ion component composed of a rare earth metal ion contained in the acrylic resin. The phosphate group preferably exists in the form chemically bonded to the structure of a polymer constituting the acrylic resin, and the polymer constituting the acrylic resin is preferably a copolymer obtained by copolymerizing a phosphate group-containing monomer represented by the following formula (1) and a monomer copolymerizable therewith:

              PO(OH) n R 3-n      Formula (1)

      wherein R means a polymerizable functional group represented by the following formula (2), and n is 1 or 2:

              CH 2 =CXCOO(C 2 H 4 O) m -     Formula (2)

      wherein X denotes a hydrogen atom or a methyl group, and m is an integer of 0 to 5.
    • 这里公开了具有特定波长范围内的射线被高效率地吸收的性能特性的塑料光学材料,可以得到良好的防眩光性,还具有低吸水性等所需的光学特性,以及其制造方法。 塑料光学材料包括丙烯酸树脂,磷酸酯基,酰胺基和由丙烯酸树脂中所含的稀土金属离子组成的金属离子组分。 磷酸酯基优选以与构成丙烯酸树脂的聚合物的结构化学键合的形式存在,构成丙烯酸树脂的聚合物优选是通过将由下式(1)表示的含磷酸根基团的单体和 可与其共聚的单体:PO(OH)nR 3-n其中R表示由下式(2)表示的可聚合官能团,n为1或2:CH 2 = CXCOO(C 2 H 4 O)m - ,其中X表示氢原子或 甲基,m为0〜5的整数。
