    Abstract: A method of making a coatable composition includes: a) providing a initial composition comprising silica nanoparticles dispersed in an aqueous liquid medium, wherein the silica nanoparticles have a particle size distribution with an average particle size of less than or equal to 100 nanometers, and wherein the silica sol has a pH greater than 6; b) acidifying the initial composition to a pH of less than or equal to 4 using inorganic acid to provide an acidified composition; and c) dissolving at least one metal compound in the acidified composition to provide a coatable composition. Coatable compositions and soil-resistant compositions, preparable by the method, are also disclosed. Soil-resistant articles including the soil-resistant compositions are also disclosed.

    Abstract translation: 制备可涂布的组合物的方法，包括：a）提供初始组合物，包括在wässrige液体介质分散在二氧化硅纳米粒子，worin的二氧化硅纳米制品具有小于或等于100纳米米平均粒径与粒径分布，和 worin硅溶胶的pH大于6; b）使用无机酸，以提供酸化的组合物酸化的初始组合物的pH值小于或等于4; 和c）溶解在酸化，以提供可涂布的组合物中的组合物的至少一种金属化合物。 可涂敷组合物和防污组合物，由该方法制备的，被光盘游离缺失。 因此防污文章，包括防污组合物是游离缺失盘。
