POLYCARBONATE RESIN COMPOSITION

The present invention seeks to provide a resin composition which contains an aromatic polycarbonate resin and a polyester resin and which has excellent mechanical strength, flowability and thermal stability and also has excellent moist heat resistance together. The present invention is a resin composition containing 50 to 99 parts by weight of an aromatic polycarbonate resin (component A) and 1 to 50 parts by weight of a polyester resin (component B), the component B being a polyester resin polymerized in the presence of a titanium-phosphorus catalyst obtained by reacting titanium tetrabutoxide, etc., with monolauryl phosphate, etc.
