ABSTRACT:
Dye-donor element for use according to thermal dye transfer methods, said element comprising a support having thereon a dye-binder layer comprising a dye corresponding to the general formula: ##STR1## wherein A represents the atoms completing a (hetero)aromatic ring system, which may be substituted or not, Y is O, S, or NR.sup.1, X stands for N-Ar, N-Het, N-N=Het, or CR.sup.2 R.sup.3, R.sup.1 is H, (un)substituted alkyl, (un)substituted cycloalkyl, (un)substituted aryl, --SO.sub.2 R.sup.4, --COR.sup.4, --CSR.sup.4, or --POR.sup.4 R.sup.5, Ar is an aromatic nucleus, which is substituted in para-position with amino, alkyloxy, aryloxy, alkylthio, arylthio, which groups may be substituted, or with hydroxy and mercapto, and which aromatic nucleus may also be substituted in other positions with alkyl, aryl, or an acylamido group, Het represents a substituted or unsubstituted heterocyclic ring, R.sup.2 and R.sup.3 each independently represent H, alkyl, cycloalkyl, aryl, alkenyl, alkynyl, a heterocyclic ring, cyano, a halogen atom, --SO.sub.2 R.sup.4, --COR.sup.4, --CSR.sup.4, or --POR.sup.4 R.sup.5, or R.sup.2 and R.sup.3 together represent the atoms necessary to complete a substituted or unsubstituted ring system including a substituted or unsubstituted heterocyclic ring system, and R.sup.4 and R.sup.5 each independently represent alkyl, cycloalkyl, aryl, alkenyl, aralkyl, alkyloxy, aryloxy, alkylthio, arylthio, amino, or a heterocyclic ring, or R.sup.4 and R.sup.5 together represent the atoms completing a 5- or 6-membered ring system.
