Abstract
PURPOSE:To obtain a press-molded article which is excellent in transparency and has lustrous and durable surface and enough strength by a method wherein unsaturated polyester resin molding composition, which essentially consists of unsaturated polyester resin, inorganic filler having specified refractive index and radical polymerization initiator, is integrally molded and hardened together with unsaturated polyester resin gelcoat surface layer, which is applied and hardened onto the surface of a mold. CONSTITUTION:Molding composition, which essentially consists of, unsaturated polyester resin, inorganic filler having a refractive index of 1.48-1.62 and radical polymerization initiator, is integrally molded and hardened together with unsaturated polyester resin gelcoat surface layer, which is applied and hardened in advance onto the heated surface of a mold in order to manufacture an unsaturated polyester resin molded item with improved transparency. The inorganic filler having the refractive index of 1.48-1.62 not only gives transparency to the molded article but also is essentially indispensable for obtaining a weighty marble-like product with high commercial value. Inorganic filler with comparatively large specific gravity is suitable for the filler. The proper fill of the filler is 60-400 parts by weight per 100 parts by weight of unsaturated polyester resin.
