A heat transferable dye donor element includes a heat transferable dye and an N-oxyl radical light stabilizer that is derived from a hindered amine. The N-oxyl radical has the following formula, wherein R, R, R, and Rare each independently selected from a straight or branched C-Calkyl, and Rand Rare each independently selected from H, OH, OR, COOH, or COOR, wherein R is a straight or branched C-Calkyl or alkene, and has a molecular weight of 600 or less. The dye donor element includes a heat transferable material that can be in one or more sections or patches including heat transferable dye patches. The heat transferable material provides better dye image stability when applied to a thermal receiver element.
