A water- and oil-repellent composition consisting of (A) a
fluorine-containing copolymer comprising at least 20% by weight (based on
the copolymer) of (a1) units derived from a polymerizable monomer having
a C.sub.1-6 polyfluoroalkyl group or a polyfluoroalkenyl group, (B) a
surfactant component comprising as the essential components (b1) a
nonionic surfactant having an HLB value of 12 or below and (b2) a
nonionic surfactant having an HLB value of 15 or above, and (C) an
aqueous medium substantially consisting of water. This composition is
free from operationally or environmentally undesirable solvents and
superior to conventional ones in stabilities such as mechanical
stability, chemical stability, and long-term shelf stability.
