Provided is a water- and oil-repellent agent composition, which gives excellent water- and oil-repellency to a substrate such as a fiber product and the like, and has excellent polymer adhesion prevention for a roll in processing thereof. The water- and oil-repellent agent composition of the present invention comprises a fluorine-containing polymer including (a) a repeating unit derived from a fluorine-containing monomer having a fluoroalkyl group, (b) a repeating unit derived from a second monomer which is an acrylate monomer having a linear or branched hydrocarbon group having 12 to 30 carbon atoms, and (c) a repeating unit derived from a third monomer which is a (meth)acrylate monomer having 50°C or more of a glass transition point (Tg) or melting point (Tm) of a homopolymer. In the fluorine-containing polymer, 82 to 99.9 or 2 to 60 parts by weight of the second monomer (b) and 0.1 to 18 or 40 to 98 parts by weight of the third monomer (c) are included with respect to 100 parts by weight of the sum of the second and third monomers (b, c). 본 발명은, 섬유 제품 등의 기재에 우수한 발수 발유성을 부여하고, 그의 가공 처리에 있어서 롤에 대한 중합체 부착성 방지가 우수한 발수 발유제 조성물을 제공한다. (a) 플루오로알킬기를 갖는 불소 함유 단량체로부터 유도된 반복 단위, (b) 탄소수 12 내지 30의 직쇄상 또는 분지상의 탄화수소기를 갖는 아크릴레이트 단량체인 제2 단량체로부터 유도된 반복 단위 및 (c) 단독 중합체의 유리 전이점(Tg) 또는 융점(Tm)이 50℃ 이상인 (메트)아크릴레이트 단량체인 제3 단량체로부터 유도된 반복 단위 를 갖는 불소 함유 중합체를 함유하는 불소 함유 조성물이며, 불소 함유 중합체에 있어서, 제2 단량체 (b)와 제3 단량체 (c)의 양의 합계100중량부에 대하여 제2 단량체 (b)의 양이 82 내지 99.9중량부 또는 2 내지 60중량부이고, 제3 단량체 (c)의 양이 0.1 내지 18중량부 또는 40 내지 98중량부인 불소 함유 조성물.
