Zusammenfassung:	To provide a water repellent composition whereby a moisture permeable waterproof film is rendered less likely to be peeled from an article treated by the water-repellent composition. The water repellent composition comprises a copolymer (A) having structural units based on a monomer (a) and structural units based on a monomer (b), a polymer (B) having an amino group, an ammonium salt group or an amide group as a pendant group, and an aqueous medium. The monomer (a) is a compound represented by R F -Q-Z-C(O)C(R)=CH 2 (wherein R F is a C 4-6 perfluoroalkyl group, Q is either a divalent hydrocarbon group containing no fluorine atom or a single bond, Z is -O- or NH-, and R is a hydrogen atom, a methyl group or a chlorine atom). The monomer (b) is a (meth)acrylate having no polyfluoroalkyl group and having a C 12-22 alkyl group.
