Abstract: The present invention provides a dye-donor element for use according to thermal dye sublimation transfer. The dye-donor element comprises a support having thereon a dye layer comprising a polymeric binder and a dye corresponding to the following general formula (I): ##STR1## wherein: Z represents hydrogen or a substituent.X represents N-R or ##STR2## R represents NR.sup.3 R.sup.4 or the residue of an aromatic coupling compound E-Q wherein Q is a group displaceable by a diazotized amine:R.sup.1 represents NR.sup.3 R.sup.4, OR.sup.12 or SR.sup.12 ;R.sup.2 represents hydrogen, cyano, COR.sup.13, CO.sub.2 R.sup.13, CONR.sup.14 R.sup.15, SO.sub.2 R.sup.16 ;R.sup.3 and R.sup.4 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an a heterocyclic group or R.sup.3 and R.sup.
