Abstract: A method is provided for after-treating fabric with a fluoroacrylate emulsion by immersion, typically under poorly-controlled conditions (e.g. field conditions), and a second embodiment of this method is provided for treating large, previously manufactured items comprising fabric (e.g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In both embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system containing an amphoteric surfactant, essentially a single particulate fluoroacrylate copolymer having repeating units of the formulas I and II ##STR1## wherein R.sub.f is a fluorinated alkyl radical; R and R.sup.1 are hydrogen or alkyl; and R.sup.2 is hydrogen or substituted or unsubstituted alkyl. The aqueous dispersion further contains, in addition to the surfactant system, a minor amount of polar organic liquid.

Abstract: A method is provided for after-treating fabric with a fluoroacrylate emulsion by spraying or immersion. The immersion can be carried out in a laundering process (preferably in a late cycle of the process) or even under poorly-controlled conditions (e.g. field conditions). The spraying embodiment of this method is useful for treating large, previously manufactured items comprising fabric (e.g. upholstered furniture, tents, awnings, and the like) with an aerosol spray containing micrometer or submicrometer-sized droplets of a diluted version of the fluoroacrylate emulsion. In all embodiments, the fluoroacrylate emulsion contains, dispersed therein with the aid of a surfactant system, essentially a single hydrophobic component comprising a particulate fluoroacrylate copolymer having repeating units of the formulas I and II ##STR1## wherein R.sub.f is a C.sub.8 -rich fluorinated alkyl radical; R and R.sup.1 are hydrogen or alkyl; and R.sup.2 is hydrogen or substituted or unsubstituted alkyl.

Abstract: An image-printing process comprising applying to a substrate a printing ink containing from about 0.01% to 1.0%, based on the total weight of the ink, of a fluorocarbon surfactant containing a fluorocarbon moiety selected from the group.Cf.sub.3 (cf.sub.2).sub.3 cf.sub.3 cf(cf.sub.3)o-, and CF.sub.3 CF(CF.sub.3)CF.sub.2 -, the surfactant containing at least 25% fluorine by weight; also, printing inks containing particular surfactants having the CF.sub.3 (CF.sub.2).sub.3 moiety.
