Appeal No. 1996-3867 Application No. 08/153,239 a composition containing a soluble polymer dissolved in or an insoluble polymer dispersed in a medium which is predominantly composed of water, or mixtures thereof. The term “predominantly” is not specifically defined in the specification. One definition of “predominate” is “[t]o be a greater . . . quantity.” This definition would mean that2 water is present in an amount of at least 50% in the medium, a fact entirely consistent with the amount of water employed in the examples at pages 7 through 14 of the specification. Moreover, according to pages 5 and 6 of the specification, a gas having the claimed solubility factor includes carbon dioxide and nitrous oxide. As found by the examiner (Answer, page 3), the sole prior art reference, Glancy, describes using carbon dioxide as a useful compressed gas for a polymer coating composition. See Glancy, page 21, line 11. Glancy, however, does not teach, nor would have suggested, using carbon dioxide as a compressed gas for the claimed “waterborne polymer coating composition.” Glancy teaches away from using more than 30% of water in the solvent/diluent in a polymer coating composition.
