    • A multi-layer article (40) that includes a layer of a water-soluble polymer that provides a water-removable, non tacky film (34) over an adhesive layer and/or acts as an adhesive for securing the multi-layer article to a substrate, such as concrete, when wetted. The article forms a water barrier capable of being secured to an area of potential water flow including a layer of flexible, water-impermeable sheet material having a layer of adhesive coated thereover, and a continuous or discontinuous coating of a water-soluble polymer thereon. When the water-soluble polymer is wetted to at least partially solubilize the water-soluble coating, the polymer and/or the underlying adhesive layer readily adheres the article to a substrate at the area of potential water flow. In a preferred embodiment, the flexible sheet material includes a layer of adhesive (tacky material) and the adhesive layer is coated with the layer of water-soluble polymer to eliminate the necessity of using a sheet of release paper to prevent the adhesive layer from adhering to itself, when in roll form, and during handling and installation.
    • 一种多层制品(40)做了包括一种水溶性聚合物的层确实提供了一个水移动的,非粘性的电影(34)上,在粘接剂层和/或作为在粘合剂用于固定所述多层制品 一个基板,彩色:如混凝土,当润湿。 所述物品形成能够被固定到在电位水流,其包括具有在涂有粘合剂的层的柔性,不透水性片材的层,和在其上的水溶性聚合物的连续或不连续的涂层的区域中的水的屏障。 当水溶性聚合物被润湿以至少部分地溶解所述水溶性涂层,所述聚合物和/或下面的粘合剂层容易附着在潜在水流的区域中的物品到一基底上。 在优选的实施例中的柔性片材料包括粘合剂(粘性材料)和粘合剂层的层涂布有水溶性聚合物的层以消除使用脱模纸的片材以防止粘合剂层附着的必要性 本身,卷状,并在当搬运和安装。
