Abstract: A fluorescent and/or phosphorescent coating composition, particularly useful as a body coating, hair coating, lipstick and particularly as a phosphorescent nail polish that has the capability of changing from transparent, or other color, in light to a phosphorescing or fluorescing composition upon the withdrawal of light. The composition, e.g., nail polish, will return to its original color, as originally perceived by a human eye, as soon as light again contacts and is absorbed by the phosphorescent or fluorescent composition. The nail polish of the present invention is capable of undergoing a reversible chemical change upon the withdrawal of light without altering its physical properties.
