Aqueous fluorochemical compositions and abrasion-resistant coatings therefrom
 Water-based coating compositions comprise an aqueous solution, emulsion, or dispersion of (a) a water-soluble or water-dispersible polymer or oligomer having at least one anionic moiety which is capable of reacting with an oxazoline or oxazine moiety; (b) a water-soluble or water-dispersible polymer or oligomer having at least one oxazoline or oxazine moiety; and (c) a sol comprising a colloidal dispersion of surface-modified, inorganic microparticles in liquid; at least one of the components (a), (b), and (c) further comprising at least one fluoroaliphatic moiety. The compositions can be used to form hard coatings having low surface energy and high abrasion resistance.
