Abstract

The present invention relates to a copolycarbonate resin composition comprising a copolycarbonate in which a specific siloxane compound is introduced in a main chain of the polycarbonate, and a UV stabilizer. Since the present copolycarbonate resin composition has excellent weather resistance, the article prepared by using this composition exhibits less deteriorated surface quality and physical properties caused by ultraviolet rays or the like when exposed to the outside.
