Abstract
Provided is a thermoplastic resin composition having excellent weather resistance, impact resistance, and fluidity and also excellent color developing properties and residence heat stability. A graft copolymer (A) prepared by graft polymerization of a certain amount of a specific monomer ()onto a certain amount of composite rubber () composed of a conjugated diene rubber polymer and a cross-linked acrylic ester polymer. The tetrahydrofuran-soluble portion of the composite rubber () has a weight-average molecular weight of 50000 or more in terms of polystyrene and a degree of swelling in toluene of 7.0 or more, or in the composite rubber contained in the graft copolymer, the number of particles having an equivalent-circle diameter of 150 nm or less is 50% or less of the total number of the composite rubber particles.
