    • 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.
    • 本发明涉及基本上水分透明的水性涂料组合物,特别是地板抛光组合物,其含有低分子量的高亲水性加成共聚物,水混溶性有机聚结剂或增塑剂,以及作为任选组分的多价金属化合物, 可溶性树脂和蜡,具有或不具有蜡可溶性树脂。 使用包含衍生自这些组合物的透明涂层的组合物和制品的方法也包括在本发明中。 本发明的组合物当与诸如润湿剂和流平剂之类的所需添加剂配制并调节至7.0至约10或更高的最终碱性pH时,基本上是水清除或基本澄清的溶液,其在施用于底物之后 ,干燥以形成透明的非常光泽的涂层,光泽度明显高于已知的抛光组合物,并且使用碱性或洗涤剂溶液除去比以前的抛光更容易实现的抛光涂层。
