PROBLEM TO BE SOLVED: To obtain a composition dealt with color unevenness of the welded parts involved therein while retaining the impact resistance and heat resistance of the original resin, and useful for e.g. television cabinets, by incorporating a rubber-modified styrene-based resin with specific spherical particles. SOLUTION: This composition is obtained by incorporating (A) 100 pts.wt. of a rubber-modified styrene-based resin with (B) 2-6 pts.wt. of spherical particles 0.1-150μm is in average size (pref. carbon microbeads). It is recommended that, specifically, for example, as the component A, a resin composed of a styrene- based polymer as continuous phase and a rubbery polymer as disperse phase is used, and both the components A and B are dry-blended with each other using a Henschel mixer and then kneaded in a twin-screw extruder at a cylinder temperature of 200-230 deg.C.
