ABSTRACT:
Quinophthalone derivatives have the general formula IwhereR1, R2, R3and R5are independently hydrogen, halogen or C1-C4-alkyl;R4is —SO3H, —SO3+N+R6R7R8R9, —SO2NR6R7, —CH2NR6R7, —CH2R10, —COOH, —COO−N+R6R7R8R9, —COOR11, —COR11, —NO2or C1-C4-alkyl;R6, R7, R8and R9are independently hydrogen; C1-C22-alkyl or C2-C22-alkenyl whose carbon chains may be interrupted by one or more moieties selected from the group consisting of —O—, —S—, —NR12—, —CO— and —SO2— and/or which may each be mono- or polysubstituted by hydroxyl, halogen, aryl, C1-C4-alkoxy and/or acetyl; C3-C8-cycloalkyl whose carbon skeleton may be interrupted by one or more moieties selected from the group consisting of —O—, —S—, —NR12— and —CO— and/or which may be mono- or polysubstituted by hydroxyl, halogen, aryl, C1-C4-alkoxy and/or acetyl; dehydroabietyl or aryl; R6and R7or R6, R7and R8are together a 5- to 7-membered cyclic radical which includes the nitrogen atom and may include further heteroatoms;R10isR11is alkyl R6;R12is hydrogen or C1-C4-alkyl;X1, X2and X3: are independently arylene, which may be substituted by halogen, arylsulfonyl or —COR13or —CO—C6H4—CO—;R13is C1-C3-alkyl or phenyl.
