Abstract
A hydrolyzate resulting from co-hydrolysis of a perfluoroalkyl group-containing organic silicon compound and a hydrolyzable group-containing methylpolysiloxane compound in a hydrophilic solvent is blended with an organopolysiloxane and a strong acid to constitute a water repellent composition which is effective for imparting water repellency and facilitating falling of water droplets and thus imparting excellent water repellency and stain-proofness to a surface of an article treated therewith.
