A method of making a coatable composition includes: providing a first composition comprising silica nanoparticles dispersed in an aqueous liquid vehicle, wherein the first composition has a pH greater than 6; acidifying the first composition to a pH of less than or equal to 4 using inorganic acid to provide a second composition; and dissolving at least one metal compound in the second composition to form the coatable composition. The silica nanoparticles have a polymodal particle size distribution, wherein the polymodal particle size distribution comprises a first mode having a first particle size in the range of from 8 to 35 nanometers, wherein the polymodal particle size distribution comprises a second mode having a second particle size in the range of from 2 to 20 nanometers, wherein the first particle size is greater than the second particle size. Coatable compositions, antistatic compositions, preparable by the method are also disclosed. Soil-resistant articles including the antistatic compositions are also disclosed.
