Abstract
Disclosed is a resin composition produced by melt-kneading a white pigment and a wholly aromatic thermotropic liquid crystal polyester. The resin composition can retain the excellent heat resistance and moldability of the wholly aromatic thermotropic liquid crystal polyester and have a satisfactory level of white light reflectance. The resin composition comprises 35 to 100 parts by weight of a white pigment particle and 100 parts by weight of a wholly aromatic thermotropic liquid crystal polyester, wherein the white pigment particle comprises 3 to 15 mass % of aluminum oxide and 97 to 85 mass % of a white pigment produced by a process including a roasting step and having a surface treated with the aluminum oxide (provided that the sum total of the white pigment and aluminum oxide is defined as 100 mass %). The resin composition can be produced by a process including a melt-kneading step.
