Abstract
Provided is a water repellent composition which does not use a fluorine-containing monomer, especially a fluoroalkyl group-containing monomer. A water repellent composition which contains (1) (a) a polymer which has a repeating unit derived from an amide group-containing monomer that is represented by formula: (wherein R1 represents an organic residue having an ethylenically unsaturated polymerizable group; R2 represents a hydrocarbon group having 7-30 carbon atoms; and R3 represents a hydrocarbon group having 1-5 carbon atoms) in an amount of 2-100% by weight relative to the polymer, and (2) a liquid medium.
