The present invention provides a water repellent composition which gives excellent water repellency and does not use a fluoroalkyl group-containing monomer, preferably a fluorine-containing monomer. The water repellent composition is a water repellent composition containing the following (1) to (3): (1) a polymer having a repeating unit derived from the amide group-containing monomer (a) represented by the following formula in an amount of 2 to 100% by mass based on the polymer, [in the formula, R1 represents an organic residue having an ethylenically unsaturated polymerizable group, R2 is a hydrocarbon group having 7 to 30 carbon atoms, R3 is a hydrocarbon group having 1 to 5 carbon atoms]; (2) a concomitant agent containing at least one concomitant agent compound selected from the group consisting of a blocked isocyanate compounds, melamine resins, silicone polymers, waxes, acetylene emulsifiers and polyoxyalkylene group-containing emulsifiers; and (3) a liquid medium. |
