摘要：
This disclosure provides coatings that eliminate the problem of persistent oil or grease smudges deposited on transparent coatings. Some variations provide an oil-smudge-resistant material comprising discrete inclusions dispersed within a continuous matrix, wherein one of the discrete inclusions and the continuous matrix is an oleophobic material, and the other is an oleophilic material. Specific embodiments incorporate segmented polyurethanes with oleophobic fluoropolymers and oleophilic hydrocarbons. Some embodiments utilize inorganic oleophilic particles in an oleophobic matrix. Some embodiments condense urethane-silane crosslinkers with other silanes to form discrete domains of oleophobic or oleophilic silanes within a continuous matrix of oleophilic or oleophobic polymer. Waterborne coatings are provided in which one of the discrete inclusions and the continuous matrix is derived from an aqueous dispersion of a linear crosslinkable polyurethane containing charged groups, and the other is derived from a crosslinking agent containing charged groups.
摘要（中）：
本公开提供了消除沉积在透明涂层上的持久性油或油脂污迹的问题的涂层。 一些变型提供了包含分散在连续基质内的离散内含物的抗油污涂料，其中离散内含物和连续基质中的一种是疏油材料，另一种是亲油材料。 具体实施方式将嵌段聚氨酯与疏油氟聚合物和亲油性烃结合。 一些实施例在疏油基质中利用无机亲油粒子。 一些实施方案将氨基甲酸酯 - 硅烷交联剂与其它硅烷缩合以在亲油或疏油聚合物的连续基质内形成疏油或亲油硅烷的离散域。 提供了水性涂料，其中离散内含物和连续基质中的一种衍生自含有带电基团的线性可交联聚氨酯的水分散体，另一种衍生自含有带电基团的交联剂。
