Abstract
To provide a water/oil resistant composition this imparts a sufficient water/oil resistance to a base material when a fluorinated copolymer having an Rf group with at most 6 carbon atoms is used. The water/oil resistance is not substantially influenced by an adjuvant or the pH of dilution water, and the composition has little odor. Also provided are a treated article and production processes. The water/oil resistant composition has a fluorinated copolymer dispersed or dissolved in a medium, and the fluorinated copolymer is one having one, some or all of amino groups in a fluorinated copolymer comprising structural units based on a monomer (a) having a C1-6 Rf group and structural units based on a monomer (b) having an amino group, converted to form a salt with an organic acid comprising an organic acid having a pKa of from 2.0 to 4.0.
