Provided is a water-repellent composition which imparts excellent water repellency and does not use a fluoroalkyl group-containing monomer, but preferably a fluorine-containing monomer. The water-repellent composition contains (1) a polymer having 2-100 wt%, with respect to the polymer, of a repeating unit derived from an amide group-containing monomer (a) represented by the following formula [in the formula, R 1 is an organic moiety having an ethylenically unsaturated polymerizable group, R 2 is a C7-30 hydrocarbon group, and R 3 is a C1-5 hydrocarbon group], (2) a co-agent containing at least one co-agent compound selected from the group consisting of a blocked isocyanate compound, a melamine resin, a silicone polymer, a wax, an acetylene-based emulsifier, and a polyoxyalkylene group-containing emulsifier, and (3) a liquid media. |
