PURPOSE:To obtain the formed article having a prescribed flexural modulus and excellent surface hardness, scratch resistance, rigidity, impact resistance, heat-resistance, chemical resistance and weather resistance and useful for glazing material, etc., by laminating a specific transparent resin layer having high hardness and a prescribed thickness to the surface of a transparent formed resin article. CONSTITUTION:The formed article having a flexural modulus of 350kgf/mm<2> or larger is produced by laminating a transparent hard resin layer having a thickness of 0.2mm or larger, a pencil hardness of 4H or higher, a Rockwell M-scale hardness of 100 or higher and total visible light transmittance of 85% or higher, e.g. a resin having a structure of formula (X is O or S), to a surface of a transparent formed resin article having a total visible light transmittance of 85% or higher, e.g. a formed article of polymethyl methacrylate resin. |
