본 발명은 수성 분산액을 포함하는 조성물에 관한 것이며, 상기 수성 분산액은 a) 80 nm 내지 500 nm 범위의 z-평균 입자 크기를 갖는 중합체 입자; b) 1 m 내지 30 m 범위의 D50 입자 크기를 갖는 중합체성 가교된 유기 마이크로스피어; c); 착색제 및 d) 아연 또는 지르코늄 화합물을 포함한다. 본 발명의 조성물은 딥 베이스 저광택 페인트 제형으로부터 제조된 코팅으로부터의 침출을 줄이는 데 유용하다. The present invention relates to a composition comprising an aqueous dispersion of a) polymer particles having a z-average particle size in the range of from 80 nm to 500 nm; b) polymeric crosslinked organic microspheres having a D50 particle size in the range of from 1 μm to 30 μm; c); a colorant and d) a zinc or zirconium compound. The composition of the present invention is useful for reducing leaching from a coating prepared from a deep base, low sheen paint formulation.
