Abstract: A coating composition, comprising a film-forming component, a radiation curable group, and a matting agent, wherein, when the composition is deposited and treated to form a cured coating, the cured coating is characterized as having a higher concentration of the matting agent in a top half of the coating relative to a bottom half of the coating. Methods of treating a liquid radiation curable coating composition on a substrate are also disclosed, comprising applying an IR treatment to the liquid radiation curable coating composition, and applying a radiation curable treatment to the liquid radiation curable coating composition. The coating composition can provide improved properties, such as improved gloss, haze, flexibility, and/or chip resistance, when incorporated into a coating, or allow the use of less matting agent when compared to conventional coating compositions.
