Abstract
Abstract A semi-solid emulsion coating composition which is shapable and fluidizable under shear when contacted to the surface of an article to be coated, and comprising at least an aqueous emulsion; a water-soluble organic solvent; a thixotropy imparting material selected from hydrogenated castor oil and condensation product of pentahydric to heptahydric sugar alcohols with aromatic aldehydes; and, if necessary, a hydrophilic polymer.
