RESIN COMPOSITION USABLE WITHOUT BEING COATED ABSTRACT OF THE DISCLOSURE Disclosed is a resin composition which is usable for an exterior article without being coated on its surface when molded into the article and is excellent in the color tone and has good impact resistance and weatherability, said composition comprising (I) 10 to 70 % by weight of a high-rubber-content graft polymer obtained by polymerizing 50 to 10 % by weight of a monomer mixture (C) comprising 10 to 90 % by weight of at least one aromatic vinyl monomer and 90 to 10 % by weight of at least one ethglenically unsaturated monomer represented by the following general formula: CH2 = CRX wherein R stands for a hydrogen atom or methyl group, and X stands for a group -CN or -COOR1 in which R1 stands for an alkyl group having to 8 carbon atoms, in the presence of a latex of a multi-layer crosslinked acrylio xubber particles containing 5 to 30 % by weight of a rigid crosslinked resin (A) having a core particle size of 0.30, to 0.40? in the interior of the rubber particles and 45 to 85 % by weight of a crosslinked acrylic acid ester polymer (B) comprising an acrylic acid ester as the main component in the outer layer of the rubber particles, so that the total amount of the components (A), (B) and (C) is 100 % by weight, (II) 90 to 30 % by weight of a thermoplastic resin obtained by polymerizing at least one alkyl acrylate or methacrylate represented by the following general formula: CH2 = CRCOOR1 wherein R stands for a hydrogen atom or methyl group, and R1 stands for an alkyl group having 1 to 8 carbon atoms, in an amount of at least 90 % by weight, and (III) O to 50 % by weight of a diene type rubber-containing thermo- plastic resin, the sum of the amounts of the components (I), (II) and (III) being 100 % by weight.
