ABSTRACT:
A resin composition comprising a thermoplastic resin and a titanium dioxide (TiO.sub.2) pigment and having a moisture content of 10-1,400 ppm as determined by a specific method. A preferable resin composition is made by (i) atomizing 0.1-3.0 wt. parts of an organopolysiloxane within a fluidized powder layer of 100 wt. parts of TiO.sub.2 pigment; (ii) mixing 1-5 wt. parts of a metallic soap with 100 wt. parts of the TiO.sub.2 pigment; (iii) heat-treating the thus-obtained mixture at 70-200.degree. C. for 10 min-2 hours; and then (iv) mixing a thermoplastic resin with the heat-treated mixture. The resin composition is used for coating paper or film, when it contains 20-60 wt. % of TiO.sub.2 pigment. The resin composition is used as a master batch for the preparation of a resin composition for coating paper or film, when it contains 30-80 wt. % of TiO.sub.2 pigment.
