본 발명은 a) 80 nm 내지 500 nm 범위의 평균 입자 크기를 갖는 중합체 입자; b) 1 μm 내지 20 μm 범위의 입자 크기를 갖는 중합체 유기 가교결합된 마이크로구형체; c) 1 μm 내지 30 μm 범위의 입자 크기를 갖는 폴리실록산 입자; d) 레올로지 개질제; e) >1.9의 굴절률을 갖는 불투명 백색 안료; 및 f) 10 중량% 미만의 저 Tg 폴리우레탄의 수성 분산액을 포함하는 페인트 조성물에 관한 것이다. 발명의 조성물은 우수한 광택 저항(burnish resistance)을 갖는 코팅을 제공한다. The present invention relates to a paint composition comprising an aqueous dispersion of a) polymer particles having an average particle size in the range of from 80 nm to 500 nm; b) polymeric organic crosslinked microspheres having a particle size in the range of from 1 μm to 20 μm; c) polysiloxane particles having a particle size in the range of from 1 μm to 30 μm; d) a rheology modifier; e) an opacifying white pigment having a refractive index of >1.9; and f) less than 10 weight percent of a low Tg polyurethane. The composition of the present invention gives coatings with excellent burnish resistance.
