Abstract: The present technology provides a UV curable coating composition, methods for forming a photocured coating on a substrate, and articles that include a substrate and a photocured coating. The UV curable coating composition includes an ethylenically unsaturated polymerizable compound, a functionalized siloxane compound, and optionally a micronized inorganic particle(s). The cured coating may provide improved dirt and/or brake dust pick-up resistance.
