    摘要: The present disclosure relates to an aqueous coating composition for imparting easy-to-clean properties to a siliceous substrate, comprising:
    a) a polyacrylic acid having a weight average molecular weight (M w ) greater than 100.000 g/mol;
    b) an organic tetrafunctional alkoxysilane;
    c) phosphoric acid; and
    d) at least 70 wt% of water, based on the weight of the overall coating composition.
    In another aspect, the present disclosure is directed to a method of imparting easy-to-clean properties to a siliceous substrate, which comprises the steps of:
    a) providing a siliceous substrate;
    b) applying a coating composition according to any of claims 1 to 22 to the siliceous substrate thereby forming a layer of the coating composition adjacent to the siliceous substrate; and
    c) drying and/or curing the layer of the coating composition thereby forming a coating layer adjacent to the siliceous substrate.
    According to still another aspect, the present disclosure is directed to a coated article comprising a siliceous substrate and a coating layer adjacent to the siliceous substrate, wherein the coating layer comprises a layer of the coating composition as described above which has been dried and/or cured onto the siliceous substrate.
