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.4 together with the atoms to which they are attached represent the atoms necessary to complete a ring:
Y represents a substituent;
n represents 0, 1, 2, 3 or 4, the substituents being the same or different when n is greater than 1 or two or more Y substituents can form an annelated ring system;
R.sup.12, R.sup.13, R.sup.14 and R.sup.15 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic ring or R.sup.3 and R.sup.4 together with the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered ring or R.sup.3 and/or R.sup.4 together with the atoms to which they are attached and one of the Y-substituents represent the necessary atoms to form a 5- or 6-membered, fused-on heterocyclic ring or R.sup.14 and R.sup.15 together with the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered ring or R.sup.13 or R.sup.14 or R.sup.15 or R.sup.14 and R.sup.15 together with one of the Y-substituents and the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered fused-on heterocyclic ring:
R.sup.16 represents hydroxy, an alkoxy group, an aryloxy group, NR.sup.17 R.sup.18, an aryl group or an alkyl group, an alkenyl group, an alkynyl group, or R.sup.16 together with one of the Y-substituents and the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered fused-on heterocyclic ring:
R.sup.17 and R.sup.18 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic ring or R.sup.17 and R.sup.18 together with the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered ring.
The present invention further provides a method for making an image using the aforementioned dye donor element.
