The invention relates to new, concentrated, liquid coloring preparations of basic dyes; it also concerns a process for dyeing and printing organic material, in particular from polymeric material and fiber material composed of copolymeric acrylonitrile using those according to the invention Coloring preparations.

It is known that basic dyes are in the in general particularly good for creating real colorations on polymeric or copolymer cream Acrylonitrile existing fiber material are suitable. Most of these basic dyes were previously used in Commercially in the form of a highly dusting powder. Working with highly dusting dye powders, which are also usually extremely colorful, but require the use of appropriate protective devices. So must z. B. the staff wear dust masks, which are mostly perceived as unhygienic or expensive ventilation equipment must be provided. They also tend to be very fine Ground dyes tend to form lumps of dye when stored in a humid atmosphere.

Furthermore, it is often difficult to obtain powdery basic Dyes dissolve in water, as they wet poorly and when adding Wasiir lumps form. This makes the preparation of dye liquors more difficult and often turns out to be very time-consuming There is therefore a need in the dyeing industry to remedy these disadvantages as completely as possible.

Various proposals have already been made for this purpose. So it was recommended to use basic Colorants in the form of concentrated solutions, the substantial proportions of organic solvents have to bring on the market. However, such basic dye solutions have several disadvantages. These solutions dry up easily when kept open. Furthermore, there is such a concentrated one Solutions of basic dyes, especially if they are exposed to strong temperature fluctuations are, the risk that the dissolved dyes when the temperature is lowered in the form of a proportion coarse crystals crystallize out, which may then grow further during storage, which means the solutions themselves become poorer in color, which allows for an exact reproduction of dye batches given composition difficult. When staining with such partially crystallized Solutions then easily result in irregular colors or even staining.

For example, a methyl violet paste is described in U.S. Patent 3,070,418 which the dye component is dissolved in a water-miscible organic solvent and meta-dihydroxybenzene is used as an essential feature. Such preparations are particularly suitable for methyl violet and are very expensive because of the large proportion of organic solvents.

New coloring preparations of basic dyes of concentrated, liquid consistency were run found which are essentially free from the disadvantages listed above.

These new, concentrated, liquid coloring preparations consist of

a) cationic color salt,

b) at least one water-soluble salt composed of the anion of an inorganic or organic, mono- or polybasic acid, the free acid of which has a p / C _s value of at most 4.8, and the cation of an inorganic, mono- or polyacid base, whose free base has a pj ^ "value of at most 4.8,

c) at least one inorganic or organic, mono- or polybasic acid, the ρ K ₁ , - value of which is at most 4.8 tx:

d) at least one cationic or nonionic Stabilizer,

c) water

There are also cationic dyes of the diphenylmethane, Triphenylmethane, oxazine and thiazine series in question and finally also color salts of the arylazo and Anthraquinone series with external onium ^ / uppe, for example an alkylammonium or a cyclammonium group.

The quantitative proportion of cationic color salt in concentrated, liquid according to the invention Dye preparations is at least about 10% and preferably 10 to 30%. The particle size of the Dye particles is advantageously from about 0.5 to

5 μ, since with larger particles there is a risk of sedimentation a part of the dye consists of the preparation.

The me ^^ cnmli2 \ ge salt content in the dye preparation should be chosen at least so high that the basic dye is essentially undissolved. The minor content required for the production of concentrated, liquid coloring preparations according to the invention depends on the one hand on the water solubility of the basic dye used and on the other hand on the solvation properties of the salt used. In certain cases a salt concentration of 3% is sufficient. The preparations according to the invention preferably contain a salt content of about 5 to 15%. A salt content of the dye preparations that is higher than that required to achieve practically complete precipitation of the basic dye is generally to be avoided, because otherwise difficulties may arise in the solubility of the dye preparations.

The quantitative proportion of an acid with a pKs value of at most 4.8 in the staining preparation about 1 to 5 percent by weight.

The quantitative proportion of cationic or niuhtionogenic stabilizer in preparations according to the invention is about 0.5 to 15 percent by weight, but preferably 2.5 to 10 percent by weight

The quantitative water content of concentrated, liquid coloring preparations according to the invention is usually between 40 and 80 percent by weight, preferably between 60 and 80 percent by weight.

Concentrated, liquid dye preparations that are particularly effective contain:

to about 10 to 30% cationic color salt,

5 to 15% of a water-soluble inorganic alkali metal or ammonium salt, in particular sodium chloride, 1 to 5% of an organic low molecular weight

Fatty acid, especially acetic acid,

2.5 to 10% of a nonionic stabilizer from the class of fatty alcohol polyglycol ethers and

40 to 80% water,

calculated on the total weight of the dye preparation of 100%.

The concentrated, liquid coloring preparations according to the invention are expediently stirred in of the cationic dye salt or cationic dye, preferably in the form of a moist Press cake, or as a powder or as an aqueous solution or suspension in the mixture of the other Components consisting of an aqueous saline solution (b), acid (c) and stabilizer (d) at room temperature or at an elevated temperature of preferably not above 50 "C, using in mixing devices commonly used in technology, such as agitators, homogenizers or kneading devices,

z. B. high-speed stirrers, turbo-buffers or kneaders. In many cases it is advantageous to use the main amount of the stabilizer only after the homogenization stir the components into the preparation. Often it also proves to be expedient, at the same time to perform a mechanical breakdown of the basic dye under the action of shear forces, for example using grinding media such as quartz sand or glass beads. The shuffling operation is complete as soon as complete homogenization is achieved, which usually takes 4 to 6 hours Case is.

Compared to powdered basic dyes, the concentrated, liquid dyes according to the invention have The main advantage of coloring preparations is that they can be changed by adding cold or warm Let the water dissolve immediately without any difficulty. Compared with previously known concentrated Solutions are distinguished by the following advantages: The dyeing preparations according to the invention do not tend to form sediments and can be stored for several months. You are above all largely insensitive to temperature fluctuations, and the undissolved that is dispersed in it The basic dye does not settle and also shows no tendency to partially crystallize out. In addition, the concentrates according to the invention are not hygroscopic and also do not tend to dry out, which is particularly feared with known concentrated solutions.

The concentrates according to the invention are ready-to-use coloring preparations. They can be diluted with water (advantageously in a ratio of at least 1:10) directly as a liquor for coloring and painting.

printing of organic materials such as leather, wool, silk, preferably cellulose acetate, tannic Cotton, and in particular for dyeing and printing fiber material made of polymer and copolymer acrylonitrile can be used. By stirring the preparations into dilute, suitable aqueous solutions Solutions containing thickeners give stable color thickenings which are excellent Suitable for use in continuous dyeing and printing processes.

The following examples illustrate the invention. The temperatures are in degrees Celsius specified. The percentages given in the examples are percentages by weight.

Example I.
