Monoazoquinolone pigments, process for their preparation and their use

Abstract

Monoazoquinolone pigments which, in one of their tautomeric forms, correspond to formula (1), wherein W is unsubstituted or substituted C6-C24aryl or unsubstituted or substituted heteroaryl or is a radical of formula (1a), wherein Ar2 is unsubstituted or substituted C6-C24aryl or unsubstituted or substituted heteroaryl, Ar1 is unsubstituted or substituted C6-C24aryl or unsubstituted or substituted heteroaryl, R, R1, and R2 are each independently of the others hydrogen, C1-C6alkyl, halogen, cyano, CF3, nitro, NR3R4, COOR4, NR4COR3, COO−X+, COR4, OR4, SR3, SO2R3, SO2NR3R4, SO3−X+, or C6-C24aryl which is unsubstituted or mono- or polysubstituted by R5, R3 is C1-C6alkyl, or C6-C12aryl which is unsubstituted or mono- or poly-substituted by halogen, hydroxy, OR7, cyano, nitro, SR7, NR6R7, COOR7, CONR6R7, NR6COR7, NR6COOR7, COO−X+, COR4, OR4, SO2R7, SO2NR6R7, SO3−X+ or by SO3R7, R4 is hydrogen or has the meanings of R3, R5 is hydrogen, C1-C4alkyl, halogen, nitro, NR7R8 or OR7, R6 is hydrogen or C1-C3alkyl, R7 and R8 are each independently of the other hydrogen; C1-C3alkyl; phenyl which is unsubstituted or mono- or poly-substituted by halogen, nitro, OR5, NR16R17; or benzyl which is unsubstituted or mono- or poly-substituted by halogen, nitro, OR5, NR16R17, and X+ is a cation H+, Li+, Na+, K+, Mg++1/2, Ca++1/2, Sr++1/2, Ba++1/2, Cu+, Cu++1/2, Zn++1/2, Mn++1/2, Al+++1/3 or [NR9R10R11R12]+, wherein R9, R10, R11 and R12 are each independently of the others hydrogen; C1-C6alkyl; phenyl which is unsubstituted or mono- or poly-substituted by C1-C6alkyl, halogen, nitro, OR5, NR16R17; or benzyl which is unsubstituted or mono- or poly-substituted by C1-C6alkyl, halogen, nitro,OR5, NR16R17, and R16 and R17 are each independently of the other hydrogen or C1-C6alkyl, are suitable for the colouring of high molecular weight material and are distinguished by good fastness properties of the resulting colourations.
