    • This invention is concerned with a modification in a composition adapted to be used for polishing floors, furniture, and the like formed of an aqueous dispersion having a pH of about 7 to 11, capable of forming a coating film having a Knoop hardness number of at least 0.5, and containing, as essential components, water, a wax, a water-insoluble addition polymer obtained by the emulsion polymerization of a monoethylenically unsaturated monomer or monomers, and a dispersing agent in a proportion from 0.5 to 20 percent by weight, based on the total weight of polymer and wax, any content of a member selected from the group consisting of waxsoluble resins and gums and alkali-soluble resins being not over 50 percent by weight, based on the weight of the polymer, any alkalisoluble resin, if present, preferably being selected from the group consisting of shellac, Manila gum, Loba gum, and alkali-soluble alkyds or polyesters, the proportions of polymer and wax being about 10 to 95 parts by weight of the polymer to 5 to 90 parts by weight of the wax, the improvement characterized by the fact that the composition also contains (1) about 1 to 50 percent by weight, based on the weight of the polymer, of a polyvalent metal compound dissociable in the composition to form polyvalent metal-containing ions, and (2) from 0 to 100 percent by weight, based on the weight of organic film-forming material, of a pigment or filler, the total solids of the composition being from about 8 to 45 percent by weight. It also concerns a method of coating substrates therewith and of removing the coating from the substrates; also the coated substrates.
    • 本发明涉及适于用于研磨由pH为约7至11的水分散体形成的地板,家具等的组合物的改性,能够形成具有诺普硬度为在 至少0.5份,并含有作为必要组分的水,蜡,通过单烯属不饱和单体或单体的乳液聚合获得的水不溶性加成聚合物和分散剂,其比例为0.5-20重量%,基于 关于聚合物和蜡的总重量,选自蜡可溶性树脂和树胶和碱溶性树脂的成分的任何含量不超过50重量%,基于聚合物的重量,任何碱溶性树脂,如果 存在,优选选自虫胶,马尼拉胶,洛巴胶和碱溶性醇酸树脂或聚酯,聚合物和蜡的比例约为10-95重量份 该聚合物的重量为5至90重量份的蜡,其改进的特征在于该组合物还含有(1)约1至50重量%,基于聚合物的重量,多价金属化合物 在组合物中可离解以形成多价含金属离子,和(2)基于有机成膜材料的重量计,颜料或填料为0-100重量%,组合物的总固体为约 8〜45重量%。 它还涉及一种用基材涂覆基材并从基材上除去涂层的方法; 也是涂覆的基材。
