Abstract The present invention relates to: a composition comprising an aqueous dispersion of microspheres and a class of a nonionic polyalkylene oxide of a distyryl or tristyryl phenol, or an anionic polyalkylene oxide salt of the distyryl or tristyryl phenol; and a method for manufacturing the composition. The microspheres have an average particle size, in the range of 1 to 25μm, as well as a low coefficient of variation and a low gel concentration. The composition is useful in coating applications, especially where a matte finish is required. 본 발명은 마이크로구형체 및 일 부류의 디스티릴 또는 트리스티릴 페놀의 비이온성 폴리알킬렌 옥사이드 또는 디스티릴 또는 트리스티릴 페놀의 음이온성 폴리알킬렌 옥사이드 염의 수성 분산물을 포함하는 조성물과 상기 조성물을 제조하는 방법에 관한 것이다. 상기 마이크로구형체는 1㎛ 내지 25㎛의 범위인 평균 입자 크기뿐만 아니라 낮은 변동 계수 및 낮은 겔 농도를 가지고; 상기 조성물은 코팅물 적용 분야, 특히 무광 마감처리가 요구되는 경우에 유용하다.
