PROBLEM TO BE SOLVED: To provide a colored resin composition which, when a titanium dioxide pigment-containing thermoplastic colored resin composition is molded to a film shape by melt extrusion at a high temperature and a high speed, causes little die lip fouling, has good releasability between a cooling roll and the resin film, and can obtain the film having high opacifying properties and whiteness. SOLUTION: The titanium dioxide pigment-containing colored resin composition comprises at least a titanium dioxide pigment, a thermoplastic resin, and a saturated aliphatic acid metallic salt having a heat loss of≤15% in a dry air atmosphere at 325°C. Film shaped melt extrusion moldings are obtained by using the composition. Photoprint paper is obtained by using a substrate for the photoprint paper in which the composition is laminated on a base.
