Pyridone dyes
First Claim
1. Pyridone dyes of the formula I ##STR57## where X is nitrogen or C--CN,R1 and R2 are identical or different and each is independently of the other unsubstituted or C1 -C4 -alkoxycarbonyl-, C1 -C4 -alkoxycarbonyloxy- or phenyl-substituted C1 -C10 -alkyl with or without interruption by from 1 to 4 oxygen atoms in ether function, C5 -C7 -cycloalkyl, C3 -C4 -alkenyl, unsubstituted or C1 -C4 -alkyl-, C1 -C4 -alkoxy- or halogen-substituted phenyl, or R1 and R2 are together with the nitrogen atom joining them together a 5- or 6-membered saturated heterocyclic radical with or without further hetero atoms,R3 is hydrogen, C1 -C10 -alkyl, C5 -C7 -cycloalkyl, or benzyl,R4 is hydrogen, C1 -C4 -alkyl or unsubstituted or C1 -C4 -alkyl-, C1 -C4 -alkoxy- or halogen-substituted phenyl,R5 is cyano, carbamoyl, mono- or di(C1 -C8 -alkyl)carbamoyl, carboxyl, C1 -C8 -alkoxycarbonyl or benzimidazolyl, andR6 is unsubstituted or phenyl-, phenoxy-, cyclohexyloxy- or pyrazolyl-substituted C1 -C10 -alkyl with or without interruption by from 1 to 4 oxygen atoms in ether function, C5 -C7 -cycloalkyl or unsubstituted or C1 -C4 -alkyl-, C1 -C4 -alkoxy- or halogen-substituted phenyl,with the proviso that the total number of carbon atoms present in the two radicals R1 and R2 is at least 7 when R1 and R2 are each C1 -C10 -alkyl or when one of R1 and R2 is C1 -C10 -alkyl and the other is C5 -C7 -cycloalkyl.

Abstract
Pyridone dyes of the formula ##STR1## where X is nitrogen or C--CN,
R1 and R2 are each substituted or unsubstituted C1 -C10 -alkyl, C5 -C7 -cycloalkyl, C3 -C4 -alkenyl or substituted or unsubstituted phenyl, or R1 and R2 together with the nitrogen atom joining them together are a heterocyclic radical,
R3 is hydrogen, C1 -C10 -alkyl, C4 -C7 -cylcoalkyl, benzyl, substituted or unsubstituted phenyl, substituted or unsubstituted furanyl or substituted or unsubstituted thienyl,
R4 is hydrogen, C1 -C4 -alkyl or substituted or unsubstituted phenyl,
R5 is cyano, carbamoyl, mono- or di(C1 -C8 -alkyl)carbamoyl, carboxyl, C1 -C8 -alkoxycarbonyl or benzimidazolyl, and
R6 is substituted or unsubstituted C1 -C10 -alkyl, C5 -C7 -cycloalkyl or substituted or unsubstituted phenyl,
are useful for dyeing or printing textile materials.
