PROBLEM TO BE SOLVED: To provide a colored unsaturated polyester resin composition of which cured material is not only excellent in low, shrinkage, surface gloss and mechanical strength, but also especially excellent in uniform coloring property, and a cured material obtained by heating the same. SOLUTION: This colored unsaturated polyester resin composition contains an unsaturated polyester, an ethylenically unsaturated monomer copolymerizable with its saturated polyester, a graft copolymer and a coloring dyestuff or pigment. The graft copolymer consists of (A) a segment consisting of a thermoplastic elastomer as a constituting component and (B) a segment consisting of a (co)polymer formed by an ethylenically unsaturated monomer showing 1.50-1.56 range refractive index as a (co)polymer, as a constituting component. The cured material of the colored unsaturated polyester resin is obtained by heating and curing the colored unsaturated polyester resin composition.
