| titleOfInvention | Optical reflection material and its manufacture and application |
| abstract | PURPOSE:To manufacture an optical reflection material of superior optical diffusion properties and two-dimensional optical transmission properties and emitting beautiful scattered light by distributing a number of small foam groups unevenly in a transparent organic glass molded material. CONSTITUTION:A foamed material composed of bead-like polymethyl methacrylate and methyl methacrylate or its prepolymer is cured together with a non-infoamable casting material of same kind in a frame. At that time, in order that the foamed material is not mixed with the non-infoamable casting material, the same is prepolymerized to a certain extent and formed into a gel-like material of agaragar shape. A molding material containing foam groups having forms such as optional letters, diagrams, symbols or patterns corresponding to the internal shape of another mold by carrying out the preliminary polimerization to said gel-like material in said mold other than the frame. Said molded material is cured integrally with a deaerated casting material in the state of being in contact with the frame, and the molded material having foam group layers in the forms of optional letters, diagrams, symbols, patterns or the like on one surface can be manufactured. |
