Acylated dicyanovinylpyrroline dye-donor element for thermal dye transfer |
摘要 |
<p>A dye-donor element for thermal dye transfer comprises a support having thereon a dye dispersed in a polymeric binder, the dye having the formula: <CHEM> wherein: R<1> and R<2> each independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to 8 carbon atoms; a cycloalkyl group having from 5 to 8 carbon atoms; or a substituted or unsubstituted alkenyl group having from 2 to 8 carbon atoms; R<1> and R<2> may represent the elements which may be taken together to form a 5- or 6-membered heterocyclic ring; each Y independently represents hydrogen; a substituted or unsubstituted alkyl group having from 1 to 8 carbon atoms; an alkoxy group OR<1>; halogen; or two adjacent Y's may represent the atoms which may be taken together to form a fused aromatic ring; n is 0 to 4; the position of Y ortho to the nitrogen may also be combined with R<1> to form a 5- or 6-membered non-aromatic, single or double nitrogen-containing, heterocyclic ring, thus forming a fused ring system; and X is a substituted or unsubstituted acyl group having from 2 to 9 carbon atoms; a substituted or unsubstituted aroyl group having from 7 to 18 carbon atoms; or a substituted or unsubstituted heteroaroyl group having from 2 to 10 carbon atoms.</p> |
