Definitions
- the present invention relates to new disazo dyes of the formula I
- X is hydrogen or -CC 4 alkyl
- R 1 is hydrogen, C 1 -C 4 alkyl, halogen, carboxyl, C 1 -C 4 alkoxy carbonyl or hydroxysulfonyl,
- R 2 is hydrogen, C 1 -C 4 alkyl, halogen, carboxyl or -CC 4 alkoxy carbonyl or R 1 and R 2 together form a radical of the formula L-NZ-CO, in which L is methylene or carbonyl and Z is C 1 -C 4 -alkyl which may be substituted by C ⁇ -C 4 alkoxy, or if appropriate by C ⁇ -C 4 alkyl or C ⁇ -C 4 -alkoxy-substituted phenyl, and
- R 3 is hydrogen, C 1 -C 4 alkyl, hydroxy, C ⁇ -C 4 alkoxy, phenoxy, C ⁇ -C mean 4 alkanoyloxy or benzoyloxy,
- the object of the present invention was to provide new acid dyes based on disazo dyes which are distinguished by advantageous performance properties.
- R 1 , R 2 , R 3 , X and Z are, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, see-butyl or tert-butyl.
- R 1 and R 2 are, for example, fluorine, chlorine, bromine, methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, isopropoxycarbonyl or butoxycarbonyl.
- Residues Z are still e.g. 2-methoxyethyl, 2-ethoxyethyl,
- R 3 radicals are furthermore, for example, methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy, sec-butoxy, formyloxy, acetyloxy, propionyloxy, butyryloxy or isobutyryloxy.
- disazo dyes of the formula I contain several hydroxysulfonyl groups, their salts are also included in the invention.
- Suitable salts are metal or ammonium salts.
- Metal salts are especially the lithium, sodium or potassium salts.
- Ammonium salts in the sense of the invention are to be understood as those salts which have either unsubstituted or substituted ammonium cations.
- Substituted ammonium cations are, for example, monoalkyl, dialkyl, trialkyl, tetraalkyl or benzyltrialkylammonium cations or cations which are derived from nitrogen-containing five- or six-membered saturated heterocycles, such as pyrrolidinium, piperidinium or morpholinium or piperazinium cations N-monoalkyl or N, N-dialkyl substituted products.
- Alkyl is generally to be understood as straight-chain or branched C ⁇ -C 2 o-alkyl, which can be substituted by 1 or 2 hydroxyl groups and / or interrupted by 1 to 4 oxygen atoms in ether function.
- Disazo dyes of the formula Ia are preferred
- Disazo dyes of the formula Ib are also preferred.
- Disazo dyes of the formula I in which R 1 is hydrogen, methyl, carboxyl, Ci- or C 2 -alkoxycarbonyl or hydroxysulfonyl are further preferred.
- Disazo dyes of the formula I in which R 2 is hydrogen, methyl, carboxyl or Coxyl ⁇ or C 2 alkoxycarbonyl are further preferred.
- Disazo dyes of the formula I in which R 3 is hydrogen or hydroxyl are also preferred.
- Disazo dyes of the formula I in which the ring A is not benzo-fused are also preferred.
- disazo dyes of the formula I in which the at least one of the radicals R 1 , R 2 and R 3 is different from hydrogen.
- Disazo dyes of the formula I in which X is hydrogen are also preferred.
- Disazo dyes of the formula I in which R 3 denotes hydroxy are particularly preferred.
- Disazo dyes of the formula I are very particularly preferred in which R 1 and R 2 are each hydrogen and R 3 is hydroxy.
- disazo dyes that have the formula lc
- the new disazo dyes of the formula I can be obtained by methods which are known per se.
- Diazonium salt which is obtained by customary diazotization of a sulfonyl compound of the formula III
- the disazo dyes of the formula I according to the invention are advantageously suitable for dyeing natural or synthetic substrates, for example wool, leather or polyamide. They are particularly suitable for dyeing leather.
- the new dyes can be used either alone or as a mixture with one another or as a mixture with other dyes.
- the dyes of the invention are also suitable for the ink jet process (paper and textiles).
- the mixture was then adjusted to a pH of 9.5 to 10 with ice-cold, dilute sodium hydroxide solution.
- the acid released by the coupling was neutralized with soda.
- the mixture was stirred overnight at a pH of 9 to 10.
- the mixture was then heated to 70 to 75 ° C., the pH was adjusted to 6 and the dye was precipitated with sodium chloride.
- the dye has the formula
- the dyeing liquors of the leather dyeings have been removed, leather is dyed in strong blue tones.
- the mixture was then heated to 75 ° C., the dye was precipitated by acidification with hydrochloric acid and suctioned off hot. After drying and grinding, 130 g of a black powder were obtained, which colored wool and polyamide in navy blue tones. Strong blue stains with good fastness to migration are obtained on leather.
- the dyeings on wool have excellent lightfastness.
- the UV-VIS spectrum shows a maximum at 603 nm in water at pH approx. 4.
- the dye has the following formula
- Example 2 were diazotized analogously to Example 1.
- the resulting diazonium salt suspension was mixed with 70.2 g of the coupling component mentioned in Example 1, which was dissolved in water at a pH of 7.5.
- the pH of the coupling mixture was adjusted to 7.5 with soda.
- the mixture was stirred for 1 h and then adjusted to a pH of 9 to 10.
- the mixture was then acidified to a pH of 4.
