Abstract (en)
[origin: EP0321923A2] A dye-donor element for laser-induced thermal dye transfer comprising a support having thereon a dye layer and an infrared-absorbing material, characterized in that the infrared-absorbing material is a cyanine dye having the following formula: <CHEM> wherein: R<1> and R<2> each independently represents a substituted or unsubstituted alkyl group; R<3>, R<4>, and R<5> each independently represents hydrogen or a substituted or unsubstituted alkyl group; or R<3> and R<4> may be joined together, directly or through one or more methyne or methylene groups to complete a substituted or unsubstituted cyclic ring of 5 to 9 members; Z<1> and Z<2> each independently represents hydrogen or the atoms necessary to complete a unsubstituted or substituted benzene or naphthalene ring; Y<1> and Y<2> each independently represents a dialkyl substituted carbon atom, a vinylene group, an oxygen atom, a sulphur atom, a selenium atom, or a nitrogen atom with an R<1> or a substituted or unsubstituted aryl group attached; J represents hydrogen; a substituted or unsubstituted alkyl group; a substituted or unsubstituted aryl group; a halogen atom; or a nitrogen atom substituted with an alkyl or aryl group, or the atoms necessary to complete a 5- or 6-membered heterocyclic ring; n is 0 or 1; and X is a monovalent anion.
