Activation energy radiation-curable silicone coating composition and coated article

An activation energy radiation-curable silicone coating composition comprising

• (A) a water dispersion of core/shell type tetragonal titanium oxide solid-solution particles, wherein said core/shell type particles each consist of a core of tetragonal titanium oxide having tin and manganese incorporated in solid solution and a shell of silicon oxide around the core, said cores have a volume basis 50% cumulative distribution diameter (D50) of up to 30 nm, and said core/shell type particles have a volume basis 50% cumulative distribution diameter (D50) of up to 50 nm, both as measured by the dynamic light scattering method, the amount of tin incorporated in solid solution is to provide a molar ratio of titanium to tin (Ti/Sn) of 10/1 to 1,000/1, and the amount of manganese incorporated in solid solution is to provide a molar ratio of titanium to manganese (Ti/Mn) of 10/1 to 1,000/1,
• (B) a polycarbonate and/or polyester-based urethane-modified vinyl polymer,
• (C) a hydrolytic condensate obtained from (co)hydrolytic condensation of at least one of a sulfur-free alkoxysilane having the general formula (1):
• R1mR2nSi(OR3)4-m-n (1)
• wherein R1 and R2 are each independently hydrogen or a substituted or unsubstituted, monovalent C1-C12 hydrocarbon group, R1 and R2 may bond together, R3 is C1-C3 alkyl, m and n are independently 0 or 1, m+n is 0, 1 or 2, and a partial hydrolytic condensate thereof,
• (D) a photo-polymerization initiator,
• (E) a solvent,
• (F) optional colloidal silica, and
• (G) a polymerizable vinyl compound other than components (B) and (C),
• the solids content of the urethane-modified vinyl polymer (B) being 1 to 30 parts by weight per 100 parts by weight of the total solids content of components (A), (C) and (F).
