Abstract
A dye-receiving element for thermal dye transfer process and assemblage comprises a support having thereon a dye image-receiving layer and a stabilizer compound having the following moiety: ##STR1## wherein each R is independently an alkyl or substituted alkyl group of from 1 to about 20 carbon atoms, or two adjacent R groups may be joined together to form methylene or ethylene; and x is as least 3. Dyes which are transferred to this receiving element have improved light stability.
