<p>PURPOSE: To provide a compsn. imparting water and oil repellency on a fiber substrate, which comprises a fluoroaliphatic radical-contg. agent and a polymer having cyclic carboxylic anhydride groups. CONSTITUTION: The compsn. comprises a fluoroaliphatic radical-contg. agent and (B) a polymer having cyclic carboxylic anhydride groups such as a copolymer of a compd. having an ethylenic unsatd. bond at its end [for example: (meth)acrylic acid ester] with a cyclic carboxylic anhydride having an ethylenic unsatd. bond. Since the compsn. has compatibility with known softeners, it can impart water and oil repellency which provides a soft touch on the substrate by treating fiber materials as well as leather, paper, plastics, metal, grass, concrete and stone, etc., therewith.</p> |
