Claim:
A 1,6,9,14-tetrasubstituted terrylenetetracarboxylic diimide of the general formula I in which the variables are defined as follows: X and Y are each independently bromine; cyano; aryloxy, arylthio, hetaryloxy or hetarylthio, each of which may be mono- or polysubstituted by C 1 -C 12 -alkyl, C 1 -C 12 -alkoxy, —COOR 1 , —SO 3 R 1 , halogen, hydroxyl, cyano, —CONHR 2 and/or —NHCOR 2 ; a radical of the formula -L-R 3 ; a radical of the formula —NR 2 2 ; R and R′ are each independently hydrogen; C 1 -C 30 -alkyl whose carbon chain may be interrupted by one or more —O—, —S—, —NR 1 —, —CO— and/or —SO 2 — groups, and which may be mono- or polysubstituted by cyano, C 1 -C 6 -alkoxy, aryl which may be substituted by C 1 -C 18 -alkyl or C 1 -C 6 -alkoxy, and/or a 5- to 7-membered heterocyclic radical which is bonded via a nitrogen atom and may contain further heteroatoms and be aromatic; C 5 -C 8 -cycloalkyl whose carbon skeleton may be interrupted by one or more —O—, —S— and/or —NR 1 — groups, and/or which may be mono- or polysubstituted by C 1 -C 6 -alkyl; aryl or hetaryl which may be mono- or polysubstituted by C 1 -C 18 -alkyl, C 1 -C 6 -alkoxy, cyano, —CONHR 2 , —NHCOR 2 and/or aryl or hetarylazo, each of which may be substituted by C 1 -C 10 -alkyl, C 1 -C 6 -alkoxy or cyano; L is 1,2-ethylene, 1,2-ethenylene or 1,2-ethynylene; R 1 is hydrogen or C 1 -C 6 -alkyl; R 2 is hydrogen; C 1 -C 18 -alkyl; aryl or hetaryl, each of which may be substituted by C 1 -C 6 -alkyl, C 1 -C 6 -alkoxy, halogen, hydroxyl, carboxyl or cyano; R 3 is C 1 -C 18 -alkyl whose carbon chain may be interrupted by one or more —O—, —S—, —NR 1 —, —CO— and/or —SO 2 — groups, and may be mono- or polysubstituted by —COOR 1 , —SO 3 R 1 , hydroxyl, cyano, C 1 -C 6 -alkoxy, aryl which may be substituted by C 1 -C 18 -alkyl or C 1 -C 6 -alkoxy, and/or a 5- to 7-membered heterocyclic radical which is bonded via a nitrogen atom and may contain further heteroatoms and be aromatic.
