    Abstract: 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.

    Abstract: A process for making solid colored particles by preparing a reaction solution in water comprising formaldehyde, urea, a cyclic polyamine functional triazine compound, and acid. A dye can be incorporated into the reaction solution if a color other than white is desired. Particles are formed having an average particle size between 1 and 70 microns without the need to resort to crushing to break up agglomerates. Particles made by this process provide excellent color and are easily washable from a substrate when incorporated into a washable formulation.Additionally, it has been found that the incorporation of colored microcapsules of average size of 1-70 microns where the color is located primarily on or in the shell of the microcapsule also provides excellent washable compositions when incorporated into a washable formulation.
