Abstract
A coated powder comprises (a) particles, and (b) a coating, on the surface of the particles. The surface coating comprises (1) optionally silica moieties, (2) organo oxysilane moieties selected from the group consisting of mono-organo oxysilane moieties, bi-organo oxysilane moieties and tri-organo oxysilane moieties, and (3) optionally organo-substituted polysiloxane moieties. The organo oxysilane moieties each have the formula R'SiO, with n=1, 2 or 3, and each R′ group is independently selected from the group consisting of alkyl, alkenyl, alkynyl, esters, amides, and at least one aromatic moiety having an absorption band maximum in the region of 280 nm to 780 nm.
