description PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition which has good flame retardance, impact resistance, moldability, external appearance excellent in gloss, and excellent long-term quality maintenance. SOLUTION: The polycarbonate resin composition is substantially composed of a sum of 100 wt.% of 45-85 wt.% aromatic polycarbonate (component A), 5-30 wt.% styrenic hard polymer (component B), 1-12 wt.% acrylic rubbery polymer (component C), 5-20 wt.% phosphoric ester compound (component D), 0.1-1 wt.% fluorine-containing dropping preventive (component E), and 0.05-2 wt.% titanium dioxide pigment (component F), and the component C is a core-shell elastic polymer obtained by graft polymerizing at least one alkyl (meth)acrylate monomer (component c2) having a 1-3C alkyl group on to a core substantially composed of a polyalkyl (meth)acrylate rubber (component c1). The polycarbonate resin composition further comprises 0.1-10 wt.% reinforcing filler (component G). COPYRIGHT: (C)2005,JPO&NCIPI
