A durably soil-resistant carpet is provided which comprises a plurality of organic fibers having thereon a normally solid coating comprising (a) at least one phase of a water-insoluble addition polymer derived from a polymerizable ethylenically unsaturated monomer free of non-vinylic fluorine, the polymer having at least one major transition temperature higher than about 45.degree. C. and a solubility parameter of at least about 8.5, and (b) at least one phase of a water-insoluble fluorinated component containing a fluoroaliphatic radical of at least 3 carbon atoms, the fluorinated component having at least one major transition temperature higher than about 45.degree.
