Abstract
An organic fine particle capable of adhering to a substrate under a state having a particle shape, wherein the organic fine particle, when adhered to a substrate, exhibits water-repellency on the substrate, and the organic fine particle is formed of a fluorine-free polymer. Also disclosed is an organic fine particle containing: (1) a hydrophobic monomer which has one ethylenically unsaturated double bond and at least one hydrocarbon group having 3-40 carbon atoms; or (2) a polymer which has a repeating unit formed from a (meth)acrylic monomer having a polydimethylsiloxane group. Also disclosed is a method for producing the organic fine particle and a water-repellent composition which is an aqueous dispersion of the organic fine particle. Also disclosed is a textile product and method for treating the same which includes applying a treatment liquid containing the water-repellent composition to the textile product.
