<P>PROBLEM TO BE SOLVED: To provide a resin material having a high-degree flame retardancy, excellent in impact resistance, excellent in surface transferability, and giving little environmental load. <P>SOLUTION: An aromatic polycarbonate resin composition includes (A) 100 pts.wt of an aromatic polycarbonate resin, (B) 10 to 100 pts.wt of a copolymer of a polylactic acid resin and/or lactic acids with another hydroxycarboxylic acid, (C) 5 to 50 pts.wt of a phosphate ester-based flame retardant, (D) 1 to 30 pts.wt of a core-shell type graft copolymer, (E) 0.1 to 2 pts.wt of a carbodiimide compound having a softening temperature of ≥50°C, and (F) 0.1 to 20 pts.wt of an inorganic filler, wherein the compositional proportions (flame retardancy parameter) α of the A component, the B component, the C component and the D component satisfies Expression (I): (flame retardancy parameter) α=[( hardly flammable parameter) A×C]/[(easily flammable parameter) B×D] and α≥1.0; the compositional proportions of the B component and the E component satisfies Expression (II): E<0.02B; and the compositional proportion of the B component and the F component satisfies Expression (III): F<0.3B. <P>COPYRIGHT: (C)2013,JPO&INPIT |
