보다 높은 안료 착색성, 저온 내충격성, 난연성을 겸비한 수지 조성물을 제공한다. 폴리오르가노실록산 및 비닐 중합체를 함유하는 고무 (A)의 존재 하에서, 1종 이상의 그래프트용 비닐 단량체 (b)를 중합한 폴리오르가노실록산 함유 그래프트 공중합체이며, 상기 고무 (A)의 굴절률이 1.47 내지 1.56의 범위 내이고, 부피 평균 입자 직경이 300 내지 2000㎚의 범위 내인 그래프트 공중합체. 상기 그래프트 공중합체와 수지를 포함하는 수지 조성물. A resin composition having all of higher pigment colorability, low-temperature impact resistance, and flame retardance is provided. A graft copolymer is a polyorganosiloxane-containing graft copolymer formed by polymerizing one or more grafting vinyl monomers (b) in the presence of a rubber (A) containing polyorganosiloxane and a vinyl polymer, wherein the index of refraction of the rubber (A) is in the range of 1.47 to 1.56, and the volume-average particle size is in the range of 300 nm to 2000 nm. A resin composition contains the graft copolymer and a resin.
