본 발명은 300 nm 내지 1000 nm의 평균 직경을 가지며, 가교된 중합체 A를 포함하는 외부 층 및 가교된 중합체 A와는 구별되는 가교된 중합체 B를 포함하는 제1 내부 층을 포함하는 중합체성 입자로서, 여기서 가교된 중합체 A는 적어도 1종의 (메트)아크릴 단량체, 가교 단량체 A, 중합 개시제 및 쇄 전달제를 포함하는 반응 혼합물의 유화 중합에 의해 수득가능한 것인 중합체성 입자에 관한 것이다. The present invention relates to a polymeric particle having an average diameter from 300 nm to 1000 nm and comprising: an outer layer comprising a cross-linked polymer A and a first inner layer comprising a cross-linked polymer B distinct from the cross-linked polymer A, wherein the cross-linked polymer A is obtainable by emulsion polymerisation of a reaction mixture comprising at least one (meth)acrylic monomer, a cross-linking monomer A, a polymerisation initiator and a chain transfer agent.
