| description | To provide a polycarbonate resin composition excellent in surface hardness and impact strength. A polycarbonate resin composition comprising at least a polycarbonate resin (a) and a polycarbonate resin (b) having structural units different from the polycarbonate resin (a), which satisfies the requirements: (i) the pencil hardness of the polycarbonate resin (a) as specified by ISO15184 is higher than the pencil hardness of the polycarbonate resin (b) as specified by ISO15184; (ii) the weight ratio of the polycarbonate resin (a) to the polycarbonate resin (b) in the polycarbonate resin is from 1:99 to 45:55; (iii) the pencil hardness of the polycarbonate resin composition as specified by ISO15184 is higher by at least two ranks than the pencil hardness of the polycarbonate resin (b) as specified by ISO15184; and (iv) the Charpy impact strength of the polycarbonate resin composition is higher than the Charpy impact strength of the polycarbonate resin (a). |
