Monoazoquinolone pigments, process for their preparation and their use

摘要

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.
