Abstract
A heat transferable material includes a heat transferable polymeric binder and a light stabilizer that is an N-oxyl radical derived from a hindered amine, the N-oxyl radical having 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 having a molecular weight of 600 or less, is described. The heat transferable material can be in one or more sections or patches on a thermal donor element to provide a protective overcoat material. Optionally, a patch in the donor element can also include a dye. The heat transferable material provides better image stability and improved iridescence when applied to a thermal, inkjet, electophotographic, or silver halide receiver.
