Abstract
Abstract A solid preparation from which a reconstituted emulsion bright-drying optionally rebuffable floor finish containing emulsion polymer, alkali-dispersible wax and optionally an alkali-soluble resin in dry particulate form which may be obtained by dehydration of an aqueous dispersion of the emulsion polymer, the wax and optionally the alkali-soluble resin at a temperature below the minimum film-forming temperature of the composition.
