ABSTRACT:
A methacrylic resin capable of selectively absorbing light rays having a wavelength of 580 nm is advantageously produced either by dispersing or dissolving neodymium compound in a resin-forming starting material selected from monomeric methyl methacrylate, a monomer mixture composed mainly of methyl methacrylate and partially polymerized products thereof, and polymerizing the resin-forming starting material. A solvent capable of dissolving therein the resin-forming starting material and the neodymium compound may be incorporated in the resin-forming starting material.
