Abstract
A surface treatment composition containing a fluorine-containing-oil-in-water emulsion prepared by emulsifying a fluorine-containing oil in water in the presence of a polymeric surfactant of a graft copolymer or block copolymer having a fluorine-containing segment and a hydrophilic segment in a molecule is an emulsion having a very excellent stability, which is superior in initial water- and oil-repellency and abrasion resistance of the water- and oil-repellency, and gives a good feeling.
