  • Patent number: 6716943
    Abstract: The invention provides a surface active agent containing fluorine, which is a copolymer composed of several ethylenic unsaturated monomers containing a fluorinated alkyl group, a silicone chain, and a polyoxyalkylene group, and the surface loss energy of which is less than 110×10−5 mJ in an organic solvent. The copolymer of the surface active agent is soluble to water and in various organic solvents, and has a good compatibility with other ingredients used to form the coating compositions. The present surface active agent reduces the dynamic surface tension of the coating composition, and thereby, have a good foam-preventing property, coating compositions containing the present surface active agent yield coated films with uniform and smooth level surfaces without forming irregularity and striation even by coating operations at high speed and high shearing force.
