Zusammenfassung:	PROBLEM TO BE SOLVED: To provide aromatic polycarbonate resin compositions well balanced with respect to flow characteristics and optical properties, and molded articles thereof. SOLUTION: Aromatic polycarbonate compositions comprise (A) an aromatic polycarbonate copolymer constituted by a dihydric phenol component having (a-1) 1,1-bis(4-hydoxyphenyl)-3,3,5-trimethylcyclohexane and (a-2) 4,4'-(m- phenylenediisopropylidene)diphenol and/or 2,2-bis(3-methyl-4-hydroxyphenyl) propane at a molar ratio of component (a-1) to component (a-2) of 99:1 to 20:80 and (B) an aromatic polycarbonate constituted by a dihydric phenol component excluding component (a-1) and component (a-2) at a weight ratio of the aromatic polycarbonate copolymer (A) to the aromatic polycarbonate (B) of 99.9:0.1 to 40:60.
