    摘要: A retroreflective article comprising a substrate and a cured ceramer coating provided on at least a portion of a surface of the substrate. The coated portion of the surface is retroreflective. The coating comprises a cured ceramer composite derived from ingredients comprising a free radically curable binder precursor and a plurality of surface treated, colloidal inorganic oxide components. The colloidal inorganic oxide components are surface treated with a surface treatment agent comprising a fluoro/silane component comprising a hydrolyzable silane moiety and a fluorinated moiety, and a crosslinkable silane component comprising a hydrolyzable silane moiety and a free radically crosslinkable moiety. The weight ratio of the crosslinkable silane component to the fluoro/silane component is from about 4:1 to 20:1, and the weight ratio of the free radically curable binder precursor to the colloidal inorganic oxide components is from about 1:10 to 8:10. A method of making a retroreflective article by coating a substrate with a ceramer composite coating is also described. A method of making a dew-resistant retroreflective article by coating a substrate with a ceramer composite coating and then surface treating the coating is also described.
