Cyan mixtures for dye transfer

Claim 1

A process for transferring dyes from a transfer to plastic-coated paper by diffusion or sublimation by means of an energy source, wherein said transfer is a transfer on which there is a dye mixture comprising at least one anthraquinone dye whose absorption maximum is at a wavelength of from 600 to 750 nm and also at least one dye selected from the group consisting of dyes of the formula I, II, IIII, IV and V ##STR50## where L 1 is C 1 -C 20 -alkyl, which may be substituted and may be interrupted by from 1 to 4 oxygen atoms in ether function, substituted or unsubstituted phenyl or hydroxyl, L 2 is a 5- or 6-membered carbocyclic or heterocyclic radical, L 3 is cyano, carbamoyl, carboxyl or C 1 C 4 -alkoxycarbonyl, L 4 is oxygen or a radical of the formula ##STR51## where Q 1 is in each case C 1 -C 8 -alkyl, which may be interrupted by 1 or 2 oxygen atoms in ether function, L 5 is hydrogen or C 1 C 4 -alkyl, L 6 and L 7 are identical or different and each is independently of the other hydrogen, substituted or unsubstituted C 1 -C 12 -alkyl, C 5 -C 7 -cycloalkyl, substituted or unsubstituted phenyl, substituted or unsubstituted pyridyl, substituted or unsubstituted C 1 -C 12 -alkanoyl, C 1 -C 12 -alkoxycarbonyl, substituted or unsubstituted C 1 -C 12 -alkylsulfonyl, C 5 -C 7 -cycloalkylsulfonyl, substituted or unsubstituted phenylsulfonyl, substituted or unsubstituted pyridylsulfonyl, substituted or unsubstituted benzoyl, pyridylcarbonyl or thienylcarbonyl, or together with the nitrogen atom joining them together are unsubstituted or C 1 -C 4 -alkyl-substituted succinimido, unsubstituted or C 1 -C 4 -alkyl-substituted phthalimido or a five- or six-membered saturated heterocyclic radical, which may contain further hetero atoms, Y is cyano or a radical of the formula CO--Q 2 , CO--OQ 2 , or CO--NHQ 2 , where Q 2 is hydrogen, C 1 -C 8 alkyl, which may be substituted and may be interrupted by 1 or 2 oxygen atoms in ether function, C 5 -C 7 -cycloalkyl, phenyl or tolyl, L 8 is hydrogen, fluorine, chlorine, methyl or a radical of the formula --NH--CO--A 1 , --NH═CO--OA 1 , --NH--CO--NA 1 A 2 , --NH--CS--OA 1 , --NH--CS--NA 1 A 2 , --NH--CO--A 3 , --NH--SO 2 --A 1 , --NH--SO 2 --A 3 or --NH--SO 2 --NA 1 A 2 , where A 1 and A 2 are identical or different and each is independently of the other C 1 -C 8 -alkyl, which may be substituted and may be interrupted by 1 or 2 oxygen atoms in ether function, C 5 -C 7 -cycloalkyl, phenyl or tolyl, or else --NAA 2 is amino, and A 3 is a five- or six-membered aromatic heterocyclic radical, which may be benzofused and contain one or more hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur, L 9 is hydrogen, fluorine or chlorine, or L 8 and L 9 together with the carbon atoms to which they are attached are a five- or six-membered aromatic carbocyclic or heterocyclic ring, L 10 is the above-mentioned radical A 3 or a radical of the formula --CO--OA 1 , --CO--NH--A 1 , --CO--NH--CO--A 1 , --CO--NH--CO--A 3 , --CO--NH--SO 2 --A 3 , --NH--CO--A 1 , --NH--CO--OA 1 , --NH--CO--NA 1 A 2 , --NH--CS--OA 1 , --NH--CS--NA 1 A 2 , --NH--CO--A 3 , --NH--SO 2 --A 1 , --NH--SO 2 --A 3 or --NH--SO 2 --NA 1 A 2 , where A 1 , A 2 and A 3 are each as defined above, L 11 is fluorine, chlorine or bromine, L 12 is hydrogen or C 1 -C 4 -alkyl, and L 13 is hydrogen, fluorine, chlorine or bromine.
