A solution type water-and-oil repellant compositionncomprising: a graft copolymer having repeating unitsnderived from a vinyl monomer having a perfluoroalkyl groupnand repeating units derived from a polymerizable cyclic acidnanhydride; and an organic solvent. The composition has highnproduct stability, is highly stable to dilution, and cannimpart high water and oil repellency. |
