PURPOSE:To obtain a light transmitting body made of antidazzling synthetic resin by forming a specified uneven structure and a specified antireflection structure on the surface of a synthetic resin plate so as to make an image on the inside of the resin plate easy to see. CONSTITUTION:The surface of a synthetic resin plate of polymethyl methacrylate, a diethylene glycol bisallyl carbonate polymer or the like is provided with 0.1-2mum Rz average surface roughness at ten spots (JIS-B-0601-1970) by coating paint having a property of forming an uneven surface or by other method. A thin interference film is then formed by vacuum deposition or other method to regulate the surface light reflectance at 500-600nm wavelengths to <=2%. Thus, the titled light transmitting body is obtd. |
