Abstract
A liquid repellent composition which can provide an article with good alcohol repellency is provided. A liquid repellent composition comprising a fluorinated polymer and an aqueous medium, wherein the fluorinated polymer comprises units based on a monomer a, units based on a monomer b and units based on a monomer c. Monomer a: a compound represented by CH2═CH—Rf (wherein Rf is a C1-8 perfluoroalkyl group). Monomer b: a fluorine-free nonionic surfactant having a polymerizable carbon-carbon double bond. Monomer c: another monomer copolymerizable with the monomer a and the monomer b.
