PURPOSE:To obtain a film with high antifogging potential semi-permanently, by performing corona discharge on a polyolefin film followed by coating the resultant film surface with specific monomer to carry out a surface graft polymetization to introduce hydrophillic group into said surface. CONSTITUTION:A polyolefin film is subjected to 1 millijoule/cm2-10joule/cm2 of an energy by corona discharge in the atmosphere followed by coating on its surface, in an N2 gas atmosphere, (A) a solution of highly hydrophillic radical- polymerizable monomer incorporated with reducing agent capable of forming redox-type catalyst to proceed with graft polymerization to introduce hydrophillic group into the surface. Said monomer is e.g. acrylamide, 2-acrylamide-2- methylpropanesulfonic aicd, acrylic acid.
