<p>A thermal transfer transfer-sheet comprises a substrate sheet bearing a dye layer on one surface. The dye layer comprises a binder and a dye mixture comprising a dye of formula (I) and at least one dye of e.g. formula (II)-(VI): R1, R2 = (substituted) (cyclo)alkyl or aralkyl; R3 = alkyl, alkoxy, alkylcarbonylamino, alkylsulphonylamino, alkylaminocarbonyl, alkylaminosulphonyl (all optionally substituted), H or halogen; R4 = alkoxycarbonyl, alkylaminocarbonyl, alkoxy, aryloxy, (cyclo)alkyl, heterocyclic (all optionally substituted), H or halogen; R5 = (cyclo)alkyl, alkoxycarbonyl, alkylaminocarbonyl, alkoxy, alkylaminosulphonyl (all optionally substituted), CN, nitro, halogen or H; R6 = (cyclo)alkyl, aryl, amino (all optionally substituted), CN, nitro or halogen; R7 = (substituted) aryl, aromatic heterocyclic, CN, nitro, halogen or another electron-withdrawing group; R8 = (substituted) alkyl, cycloalkyl or NR10R11; R9 = amino or OH; R10, R11 = (substituted) alkylcarbonyl or arylcarbonyl; and l, m, n = integer, 1-4.</p> |
