Abstract
The present invention provides a polycarbonate (PC) resin composition which tends not to show amorphous-pattern contamination on the surfaces of molded articles, and is superior in terms of transparency, mechanical strength and weather resistance, etc. The PC resin composition contains (A) 100 parts by weight of a polycarbonate resin and (B) 0.0001 parts by weight or more, but less than 0.1 parts by weight, of a sulfonic acid phosphonium salt. Furthermore, the present invention also provides a PC resin composition which additionally contains (C) 0.01 to 10 parts by weight of an ultraviolet absorbing agent. ##STR1##
