    • A removable, colored X-alginate coating composition for a surface includes an aqueous solution of sodium alginate including a colorant and an aqueous solution containing divalent cations. In various aspects, the aqueous solution containing divalent cations includes, but is not limited to, calcium chloride, calcium chlorate, calcium carbonate, magnesium chloride, magnesium chlorate, or magnesium carbonate. The applied coating composition is advantageously in the form of a thin film coating. The thin film may have a thickness about equal to or greater than 10 nanometers and may include more than a single layer; for example, two mono-layers, but not limited as such. Any one of the plurality of monolayers may have a thickness about equal to or greater than five nanometers. Advantageously, the X-alginate coating composition according to the embodiments of the invention is substantially removable from the application surface on-demand upon the application of a suitable chelator. According to an advantageous embodiment, the coating composition is essentially non-toxic and bio-degradable. A reversible, colored X-alginate coating system includes a colored X-alginate coating composition and a colored X-alginate coating composition remover. The remover may be a chelator such as, but not limited to, disodium ethylenediamine tetraacetate (EDTA), ethylene glycol tetraacetic acid (EGTA), or sodium citrate. A method for reversibly coloring a surface includes applying an aqueous solution of sodium alginate including a colorant onto the surface and applying an aqueous solution containing divalent ions onto the surface, wherein the solutions are in mutual contact on the surface. Water may subsequently be applied to the coated surface as a final washing step.
    • 用于表面的可移除,着色的海藻酸锌涂料组合物包括包含着色剂的藻酸钠水溶液和含有二价阳离子的水溶液。 在各个方面,含有二价阳离子的水溶液包括但不限于氯化钙,氯酸钙,碳酸钙,氯化镁,氯酸镁或碳酸镁。 涂覆的涂料组合物有利地是薄膜涂层的形式。 薄膜可以具有大约等于或大于10纳米的厚度,并且可以包括多于单层; 例如两个单层,但不限于此。 多个单层中的任何一个可以具有大约等于或大于五纳米的厚度。 有利地,根据本发明的实施方案的X-藻酸盐涂料组合物在施用合适的螯合剂时基本可从应用表面除去。 根据有利的实施方案,涂料组合物基本上是无毒的并且是可生物降解的。 可逆的着色的海藻酸盐涂层系统包括着色的海藻酸锌涂料组合物和着色的海藻酸锌涂料组合物去除剂。 去除剂可以是螯合剂,例如但不限于乙二胺四乙酸二钠(EDTA),乙二醇四乙酸(EGTA)或柠檬酸钠。 可逆地着色表面的方法包括将包含着色剂的藻酸钠水溶液施加到表面上,并将含有二价离子的水溶液施加到表面上,其中溶液在表面上相互接触。 随后可以将水作为最后的洗涤步骤施加到涂覆的表面上。
