Definitions
- the present invention describes new water-soluble yellow azo dyes, processes for their preparation and their use as recording liquids, in particular for the ink jet process (ink-jet printing).
- the inkjet process is a non-contact printing process, generally distinguishing between two printing techniques: drop-on-demand and continuous stream.
- the drop-on-demand principle is based on the fact that the ink in the form of a drop from a nozzle - electronically controlled - is placed in the right place at the right time, whereas with continuous stream printing the ink is permanently released and then, also after electronic charging either hits the recording medium (e.g. paper), or is distracted into a receptacle.
- the recording liquids or the dyes contained therein must meet corresponding requirements, in particular with regard to lightfastness and waterfastness.
- Lightfastness is particularly important for inkjet applications in outdoor areas and in the production of inkjet prints with photographic quality.
- the present invention therefore relates to dyes of the general formula (2)
- a and B are the same or different and for an optionally with 1, 2, 3 or 4 substituents from the group Ci-C ⁇ -alkyl, hydroxy, -C-C 6 - alkoxy, carboxy, sulfo, sulfonamide, amino and -C-C 6 -Alkylamino substituted C ⁇ -Cio-aryl radical; or for a 5- to 7-membered aromatic heterocycle which can be benzo-fused and can carry 1, 2, 3 or 4 of the abovementioned substituents, or in which A represents a radical of an azo dye of the formula (2a)
- D 1 and D 2 are the same or different and for an optionally with 1, 2, 3 or 4 substituents from the group C C ⁇ -alkyl, hydroxy, Ci-C ⁇ -alkoxy, carboxy, sulfo, sulfonamide, amino and C- ⁇ -C 6 alkylamino substituted C 6 -C ⁇ o aryl;
- Y represents an oxygen and / or nitrogen-containing group which optionally forms a 9- or 10-membered ring via X of the enolate function;
- X is hydrogen, a monovalent metal cation, an equivalent of a polyvalent metal cation or an ammonium ion substituted with -CC 4 -alkyl, phenyl or (-C-C) alkoxy- (-C-C) -alkyl.
- Preferred azo dyes of the formula (2) are those in which A and B are phenyl, naphthyl, pyridyl or pyrazolyl, those with 1 or 2 substituents from the group consisting of methyl, ethyl, propyl, hydroxy, methoxy, ethoxy, propoxy and carboxy , Sulfo, sulfonamido, amino and
- Methylamino can be substituted.
- Preferred azo dyes of the formula (2) are also those in which X is hydrogen, Na, K or a transition metal cation.
- Particularly preferred azo dyes of the formula (2) are also those in which X is Cu, Co, Ni, Fe or Cr, which together with Y forms a 9- or 10-membered ring.
- X is Cu.
- the present invention also relates to a process for the preparation of the dyes of the formula (2), characterized in that the amine of the formula (3)
- reaction of (3) with (4) is preferably carried out at 0 to 40 ° C and pH 4 to 9.
- the diazotization and coupling steps can be carried out by customary methods.
- the diazotization is preferably carried out in aqueous solution or suspension
- the azo coupling is preferably added in aqueous solution or suspension
- the molar ratios between the respective diazonium salt and the respective coupling component are preferably 1: (0.8 to 2).
- the complexation with a metal is conveniently done by adding an aqueous metal salt solution, e.g. a metal sulfate, chloride, bromide, hydrogen sulfate, bicarbonate or carbonate.
- an aqueous metal salt solution e.g. a metal sulfate, chloride, bromide, hydrogen sulfate, bicarbonate or carbonate.
- the complexation can be carried out in the acidic as well as in the basic range.
- the temperature should be between 60 and 130 ° C, if necessary, heated under pressure.
- the dyes according to the invention can additionally contain a shading dye, preferably from the group of the colorants listed in the Color Index, such as C.I. Acid Yellow 17 and 23, C.I. Direct Yellow 86, 98 and 132, C.I. Reactive Yellow 37, C.I. Pigment Yellow 17, 74, 83, 97, 120, 139, 151, 155 and 180; C.I. Direct Red 1, 11, 37, 62, 75, 81, 87, 89, 95, 227; C.I. Acid Red 1, 8, 80, 81, 82, 87, 94, 115, 131, 144, 152, 154, 186, 245, 249 and 289; C.I.
- a shading dye preferably from the group of the colorants listed in the Color Index, such as C.I. Acid Yellow 17 and 23, C.I. Direct Yellow 86, 98 and 132, C.I. Reactive Yellow 37, C.I. Pigment Yellow 17, 74, 83, 97, 120, 139,
- the dyes according to the invention can be used for the surface coating of objects made of, for example, metal, wood, plastic, glass, ceramic, concrete, textile material, paper and rubber.
- the dyes according to the invention can additionally be shaded with the dyes and / or pigments listed above.
- the coupler solution (step A) can be added to the diazo solution (step B).
- the dye (7) can be added directly to an ink formulation or, as described in step D, reacted with a copper salt in order to further increase the light fastness.
- Stage D The dye solution obtained from stage C is heated to 60 ° C. and mixed with a solution consisting of 0.066 mol of copper sulfate, ammonia and diethanolamine and heated to about 90 ° C. for about 1 to 2 hours.
- the dye (8) is obtained in the form of an aqueous solution.
- Example 2 Now, as in example 1 (stages A-C), you set
- the dye solutions obtained from the examples are finely filtered through a depth filter (0.1-0.3 ⁇ m), passed over a cation exchanger and, after desalting, adjusted to color strength via a membrane desalination plant. It is then preserved with a biocide (e.g. ⁇ Proxel GXL).
- a biocide e.g. ⁇ Proxel GXL
- the prepared recording liquids are stored at 60 ° C for 4 weeks to investigate the storage stability. No precipitations are observed after this time, the recording liquids can be finely filtered without residue. Colorimetric studies show no changes to the tests made before the storage stability tests.
