Abstract
An erasably markable luminescent article formed of a coated substrate that is markable with dry wipe inks without causing permanent discernible distortion of the substrate. The surface after marking is substantially fully erasable. The surface is provided by a smooth coating of cured lacquer perferably a radiation cured lacquer, for example, electron beam radiation cured urethane acrylate. The luminescent appearance results from a phosphorescent layer between the substrate and an unpigmented cured lacquer coating.
