Abstract
This invention relates to essentially water-clear aqueous coating compositions, particularly floor polishing compositions, containing a highly hydrophilic addition copolymer of low molecular weight, a water miscible organic coalescing agent or plasticizer and, as optional components, a polyvalent metal compound, an alkali-soluble resin and a wax, with or without a wax-soluble resin. Methods of using the composition and articles containing transparent coatings derived from such compositions are also included in the invention. The compositions of this invention, when formulated with such desirable additives as wetting agents and leveling agents and adjusted to a final alkaline pH of between 7.0 to about 10 or more, are essentially water-clear or substantially clarified solutions that, after application to a substrate, dry to form clear exceptionally glossy coatings, the glossiness being markedly higher than with known polish compositions, and removal of polish coatings using alkaline or detergent solutions being effected more easily than with prior polishes.
