Disclosed is a titanium dioxide pigment in which discoloration and molecular weight reduction of a polycarbonate resin are suppressed, and silver streak hardly occurs even when blended in a polycarbonate resin at a high concentration, a production method thereof, and a highly versatile polycarbonate resin blended with the titanium dioxide pigment. Providing a composition. A polycarbonate resin comprising a coating layer of a hydrolysis product of an organosilane compound represented by the following formula 1 on the surface of titanium dioxide particles, and a coating layer of methylhydrogenpolysiloxane on the coating layer. A titanium dioxide pigment for the composition. Formula 1: R n Si (X) 4-n [R is a non-reactive functional group, X is a hydrolyzable group, n is an integer of 1 to 3, and when n is 2 or 3, the non-reactive functional group represented by R may be the same kind. It may be different, and when n is 1 or 2, the hydrolyzable group represented by X may be the same or different. ] [Selection figure] None |
