NOVELTY - A thermoplastic resin composition comprises acrylic resin (A) containing 40-90 %mass methacrylic-ester unit and/or acrylic-ester unit, 5-40 %mass aromatic vinyl compound unit and 5-30 %mass carbonyl group-containing compound unit (I), and rubber-containing copolymer particles (B) having a multilayered structure with an average particle diameter of 0.04-0.13 mu m. The content of residual monomers contained with respect to 100 %mass resin in the resin composition is 0.2-0.8 %mass. The content of component (B) contained with respect to 100 parts mass component (A) is 0.1-100 parts mass.    USE - Thermoplastic resin composition is used for forming molded product e.g. film (all claimed). Uses include but are not limited to bumper, front grille, headlamp and tire peripheral portions of motor vehicle, boats and ships, aircraft, light-guide plate for liquid crystal display and plasma display, polarizing plate protective film, liquid-crystal optical compensation film, substrate for solar cell, waveguide, optical fiber coating material, lens for light-emitting diode, etc,.    ADVANTAGE - The molded product formed using the thermoplastic resin composition has excellent optical characteristics, heat resistance and mechanical strength, and favorable slip characteristics. The generation of bleed-out on the surface of the molded product is suppressed.    DETAILED DESCRIPTION - A thermoplastic resin composition comprises acrylic resin (A) containing 40-90 %mass methacrylic-ester unit and/or acrylic-ester unit, 5-40 %mass aromatic vinyl compound unit and 5-30 %mass carbonyl group-containing compound unit of formula (I), and rubber-containing copolymer particles (B) having a multilayered structure with an average particle diameter of 0.04-0.13 mu m. The content of residual monomers contained with respect to 100 %mass resin in the thermoplastic resin composition is 0.2-0.8 %mass. The content of component (B) contained with respect to 100 parts mass component (A) is 0.1-100 parts mass.    X=O or N-R;    O=oxygen atom;    N=nitrogen atom bonded with two carbon atoms and R;and    R=H, alkyl, aryl, or cycloalkyl.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of thermoplastic resin composition, which involves passing the components (A) and (B) into a polymer filter with size of 5-20 mu m;    (2) molded product, which comprises the thermoplastic resin composition; and    (3) film, which comprises the thermoplastic resin composition.
