Abstract:
A process for preparing a thermoplastic resin composition comprising a thermoplastic resin and a titanium dioxide pigment, which comprises the steps of:atomizing 0.1 to 3.0 parts by weight of an organopolysiloxane as droplets having an average diameter of 1 to 100 .mu.m within a fluidized powder layer of 100 parts by weight of a titanium dioxide pigment;mixing 1 to 5 parts by weight of a metallic soap with 100 parts by weight of the organopolysiloxane-treated titanium dioxide pigment;heat-treating the thus-obtained mixture at a temperature of 70 to 200.degree. C. for a period of 10 minutes to 2 hours; and thenmixing a thermoplastic resin with the heat-treated mixture.
