PURPOSE: To provide a coating compsn. which has excellent adhesion to substrates and can impart water and oil repellency, stain resistance and low frictional properties to the surface of a coating film, by dissolving a specified hydrophobic graft polymer and a specified hydrophilic graft polymer in an org. solvent soln. of a film-forming resin.
CONSTITUTION: 0.1W10wt% hydrophobic graft polymer (B) having a moiety contg. 10W80wt% fluorine or silicon and a moiety compatible with film-forming resin, such as a fluoroalkyl acrylate/methyl methacrylate comb polymer, and 0.01W10wt% hydrophilic graft polymer (C) having a moiety having carboxyl groups and a moiety compatible with film-forming resin, such as a methacrylate ester-terminated copolymer of a macro monomer and acrylic acid, are blended with a soln. of a film-forming resin such as PE in an org. solvent such as toluene, each amount of components B and C being based on the solid in the soln. A.
