Zusammenfassung:PROBLEM TO BE SOLVED: To provide a flame-retardant transparent polycarbonate resin based composition excellent in flame retardancy, transparency and impact resistance, and to provide a molding formed from the flame-retardant transparent polycarbonate resin based composition and a method for producing the molding. SOLUTION: The flame-retardant transparent polycarbonate resin composition is composed of, based on 100 parts weight polycarbonate resin, 4-22 parts weight halogen-containing triazine compound and 0.01-0.2 parts weight fluorocarbon resin. It does not matter if the polycarbonate resin is a bisphenol type polycarbonate resin and has ≥16,000 viscosity-average molecular weight when measured at 20°C by using methylene chloride. The halogen-containing triazine compound consists of 2,4,6-tris(2,4,6-trihalophenoxy)-1,3,5-triazine. It does not matter if an auxiliary flame retardant such as an antimony compound is not incorporated substantially in the flame-retardant transparent polycarbonate resin composition.
