Abstract
To provide a water/oil repellent composition which is excellent in the stability as a working liquid and the water repellency whereby the occurrence of scum having a high adhesion is low, to provide its production process and to provide an article of which the surface is treated with the water/oil repellent composition whereby the occurrence of dirt is suppressed. A water/oil repellent composition which comprises a nonionic surfactant having a melting point of from 50° C. to 70° C., a fluorinated copolymer (for example, a copolymer of a (meth)acrylate having a C6 perfluoroalkyl group) and a medium containing water.

A water/oil repellent composition which comprises a nonionic surfactant having a melting point of from 50° C. to 70° C., a fluorinated copolymer and a medium containing water.
A method for producing a water/oil repellent composition, which comprises a step (1) of adding monomers containing a fluorinated monomer and a nonionic surfactant having a melting point of from 50° C. to 70° C. in a medium containing water, followed by emulsion polymerization to obtain a fluorinated copolymer emulsion, and a step (2) of preparing a water/oil repellent composition by using the fluorinated copolymer emulsion obtained in step (1).
