Abstract (en)
[origin: EP0257580A2] A dye-donor element for thermal dye transfer comprises a support having thereon a merocyanine dye dispersed in a polymeric binder, the merocyanine dye being capable of transfer by diffusion to a dye-receiving element upon the application of heat and being incapable of substantial photolysis, the merocyanine dye being substituted or unsubstituted on the bridging methine carbon atoms. In a preferred embodiment, the merocyanine dye has the formula: <CHEM> wherein: A represents -COR, -COOR, -CONHR, -CN -SO2R or -SO2NR2; or A may be combined together with R<1> to form a heterocyclic or carbocyclic ring system; R<1> represents -NHR, -NR2, -OR, -SR, or R; n represents 0 or 1; Z represents the atoms necessary to complete a 5- or 6-membered substituted or unsubstituted heterocyclic ring; and each R independently represents a substituted or unsubstituted alkyl group of from 1 to 6 carbon atoms or a substituted or unsubstituted aryl group of from 6 to 10 carbon atoms.
