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 has the following formula (A) or formula (B): wherein R, R, R, and Rare each a straight or branched C-Calkyl or alkene, and Rand Rare each independently H, CHCH, CH, OH, OR, COOH, COOR, or NH—C(═O)R, wherein R is a straight or branched C-Calkyl or alkene, and having a molecular weight of 600 or less. At least one of Rand Ris not hydrogen. The heat transferable material can be in a section or patch on a thermal donor element to provide a protective overcoat material. A patch in the donor element can include a dye. The heat transferable material provides better image stability and improved iridescence when transferred to a receiver of some type.
