摘要：
In order to provide a thermoplastic resin composition and a molded article excellent in balance of color developability and low-temperature impact resistance, a polyorganosiloxane-containing graft copolymer in which a rubber (A) containing 0.1 to 40% by mass of a polyorganosiloxane (A1) and 41 to 99.8% by mass of a vinyl polymer (A2) is grafted with 0.1 to 19% by mass of vinyl monomer (b) with respect to 100% by mass of the polyorganosiloxane-containing graft copolymer,
wherein the vinyl polymer (A2) is a vinyl polymer of 90 to 100% by mass of a monofunctional vinyl monomer (al) with 10 to 0% by mass of a polyfunctional vinyl monomer (a2), and wherein the homopolymer of the monofunctional vinyl monomer (a1) has a glass transition temperature of 0 °C or more.
wherein the vinyl polymer (A2) is a vinyl polymer of 90 to 100% by mass of a monofunctional vinyl monomer (al) with 10 to 0% by mass of a polyfunctional vinyl monomer (a2), and wherein the homopolymer of the monofunctional vinyl monomer (a1) has a glass transition temperature of 0 °C or more.
