, (2008/06/13)
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): wherein :, Z represents hydrogen or a substituent,X represents N-R or R represents NR3R4 or the residue of an aromatic coupling compound E-Q wherein Q is a group displaceable by a diazotised amine;, R1 represents NR3R4, OR12 or SR12;, R2 represents hydrogen, cyano, COR13, CO2R13, CONR14R15, SO2R16;, R3 and R4 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an a heterocyclic group or R3 and R4 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;, R12, R13, R14 and R15 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic ring or R3 and R4 together with the atoms to which they are attached represent the necessary atoms to form a 5- or 6-membered ring or R3 and/or R4 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 R14 and R15 together with the atoms to which they are attached represent the necessary atoms to form a 5- or 6- membered ring or R13 or R14 or R15 or R14 and R15 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;, R16 represents hydroxy, an alkoxy group, an aryloxy group, NR17R18, an aryl group or an alkyl group, an alkenyl group, an alkynyl group, or R16 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;, R17 and R18 each independently represent hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic ring or R17 and R18 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.
