Abstract
A fluorochemical coating composition is provided comprising (A) a hydrolyzable group-containing silane modified with a fluorooxyalkylene-containing polymer and (B) a fluorooxyalkylene-containing polymer having an average molecular weight not higher than the average molecular weight of component (A) in a weight ratio (A)/(B) of 40/60 to 95/5. The composition forms on a substrate a water/oil repellent layer which does not detract from the visibility of the substrate.
