Monoazoquinolone pigments, process for their preparation and their use

Abstract

Monoazoquilolone pigments which, in one of the tautomeric forms thereof, correspond to formula (1), wherein Ar is a radical of formula (2a), (2b), (2c), (2d), 2(e) or (2f) wherein R1 is C1-C4alkyl, R2 and R3 are each independently of the other hydrogen, halogen, C1-C4alkyl, carboxy, sulfo, cyano, C1-C4alkoxycarbonal, C1-C4alkylcarbonyl, C1-C4alkanoylamino, benzoylamino that is unsubstituted or substituted in the phenyl ring by halogen, nitro, C1-C4alkyl or by C1 -C4alkoxy; carbamoyl, N-C1-C4alkylaminocarbonyl, N-arylaminocarbonyl that is unsubstituted or substituted in the aryl moiety by halogen, nitro, C1-C4alkyl or by C1-C4alkoxy; N,N-di-C1-C4alkylaminocarbonyl, C1-C4alkoxysulfonyl, C1-C4alkylsulfonyl, sulfamoyl, N-C1-C4alkylaminosulfonyl, N-arylaminosulfonyl that is unsubstituted or substituted in the aryl moiety by halogen, nitro, C1-C4alkyl or by C1-C4alkoxy; or N,N-di-C1-C4alkylaminosulfonyl, wherein carboxy and sulfo are in the form of the free acid or in salt form, R8and R9are each independently of the other hydrogen, halogen, C1-C4alkyl, C1-C4alkoxy, carboxy, sulfo, cyano, C1-C4alkoxycarbonyl, C1-C4alkylcarbonyl, C1-C4alkanoylamino, benzoylamino that is unsubstituted or substituted in the phenyl ring by halogen, nitro, C1-C4alkyl or by C1-C4alkoxy; carbamoyl, N-C1-C4alkylaminocarbonyl, N-arylaminocarbonyl that is unsubstituted or substituted in the aryl moiety by halogen, nitro, C1-C4alkyl or C1-C4alkoxy, N,N-di-C1-C4alkylaminocarbonyl, C1-C4alkoxysulfonyl, C1-C4alkylsulfonyl, sulfamoyl, N-C1-C4alkylaminosulfonyl, N-arylaminosulfonyl that is unsubstituted or substituted in the aryl moiety by halogen, nitro, C1-C4alkyl or by C1-C4alkoxy; or N,N-di-C1-C4alkylaminosulfonyl, wherein carboxy and sulfo are in the form of the free acid or in salt form. Ar1 is an aryl radical, p is a number 0, 1 or 2, and r is a number 0, 1 or 2, wherein (R8)r in formula (2f) denodes r identical or different radicals R8, are suitable for the coloring of high molecular weight material and are distinguished by good fastness properties of the resulting colorations.
