- the coloring can be carried out both in the mass and after the leaf formation.
- DE-A-20 12 217 From DE-A-20 12 217, it is known from DE-A-20 12 217 to carry out the dyeing in the presence of cationic polymeric compounds and to remove the cationic dyes only after the addition of the cationic polymers Add compound to the fabric.
- the known auxiliaries for processes for dyeing paper have an insufficient activity when using acid dyes or direct dyes.
- the object of the invention is to provide an effective aid for a process for dyeing paper with acid dyes and / or direct dyes in an aqueous medium, which allows papers to be dyed with high color strength while largely avoiding the two-sided cylinder of the dyeing.
- water-soluble reaction products are used as cationic auxiliaries, which are obtainable by reaction of alkylating agents which have an aromatic substituent with cationic polyelectrolytes.
- Particularly effective auxiliaries for the process according to the invention are obtained if the water-soluble reaction products of alkylating agents which have an aromatic substituent and the cationic polyelectrolyte are modified in a second stage by reaction with cyanamide and / or dicyandiamide.
- Suitable dyes for the process according to the invention are acidic dyes or direct dyes and also mixtures of the two classes of dyes mentioned.
- the dyes of the classes mentioned can be found in the Color Index. Acid dyes are given, for example, in the Color Index, Volume 1, 3rd edition, The Society of Dyers and Colorists and American Association of Textile Chemists and Colorists, pages 1003-1560. Some typical acid dyes that are particularly suitable for dyeing paper are, for example, the acid yellow dyes Ci 13 065 and 47 035, the orange dyes Cl 13 090, Cl 15 575 and Cl 15 510 and the red acid dyes Cl 45 380 and Cl 15 620. Direct dyes are given in the Color Index, Volume 2, on pages 2007 to 2477.
- Typical direct dyes that are usually used for dyeing paper are the yellow direct dyes CI 29 000, CI 24 895, Ci 13 950, CI 29 025, Cl 40 000, Cl 40 001 and CI 24 890, the orange direct dyes Cl 40 215 , Cl 40 265 and 29 156, the red direct dyes CI 29 175, Cl 28 160, Cl 22120 and Cl 25 410, the blue direct dyes Cl 23 155 and Cl 24 340 and the violet direct dye Cl 25 410.

- the viscosity of the crosslinking products of ammonia and the diamines or oligoamines in a 40% aqueous solution is at most 40,000 mPas.
- Polyvinylamines are produced by free-radically polymerizing vinylformamide and saponifying the polymer in an acidic environment.
- Further cationic polyelectrolytes are condensation products containing carbonamide groups, are grafted onto the alkyleneimine units.
- This class of substances is primarily polyamidoamines which are obtained by reacting dicarboxylic acids having 4 to 10 carbon atoms with polyalkylene polyamines which have 3 to 19 basic nitrogen atoms in the molecule.
- Suitable dicarboxylic acids are, for example, succinic acid, maleic acid, adipic acid, glutaric acid, suberic acid, sebacic acid or terephthalic acid.
- mixtures of dicarboxylic acids e.g. B.
- adipic acid and glutaric acid or maleic acid and adipic acid.

- diamines such as ethylenediamine and hexamethylenediamine, or oligoamines.
- a further possibility for the preparation of such compounds is to condense urea with bis-aminoethylmethylamine.
- the water-soluble condensation products containing carbonamide groups mentioned are modified cationically by introducing alkyleneimine units.
- the easiest way to do this is e.g. B. in such a way that the condensation products in the presence of Lewis acids, for. B. boron trifluoride etherate or sulfuric acid, alkyleneimines, especially ethyleneimine, grafted.
- Lewis acids for. B. boron trifluoride etherate or sulfuric acid, alkyleneimines, especially ethyleneimine, grafted.
- alkyleneimines especially ethyleneimine
- grafting reaction based on 100 parts by weight of a condensate containing carbonamide groups, 20 to 400, preferably 50 to 300 parts by weight of ethyleneimine are used. Products of this type are known for example from DE-B-24 34 816.
- Alkyleneimine groups can also be produced by reacting aminoalkylsulfuric acid half-esters with the condensates containing carbonamide groups in the alkaline pH range.
- An aminoethylation of the condensates containing carbonamide groups is possible, for example, by reacting these products with ß-aminoethylsulfonic acid half-ester.
- the cationic polyelectrolytes are completely or only partially reacted with the alkylating agents which have an aromatic substituent. At least 10% of the aminoalkyl groups of the cationic polyelectrolyte should be reacted with the alkylating agents containing an aromatic substituent. Especially in the case of the reaction products from piperazines and epichlorohydrin, after a partial quaternization of the cationic polyelectrolytes, the proportion of quaternary nitrogen atoms in the polyelectrolyte is preferably 30 to 60%.
- auxiliaries are obtained if the reaction products of alkylating agents which have an aromatic substituent and the cationic polyelectrolyte are modified in a second stage with cyanamide or dicyandiamide or mixtures of cyanamide and dicyandiamide.
- cyanamide or dicyandiamide or mixtures of cyanamide and dicyandiamide 1 to 100, preferably 5 to 20 parts by weight of cyanamide and / or dicyanamide are used per 100 parts by weight of a partially alkylated cationic polyelectrolyte.
- the reaction is carried out in aqueous solution at temperatures in the range from 70 to 100.degree.
- paper is colored in the presence of the cationic auxiliaries described above.
- the dyeing is preferably carried out in bulk, i.e. H. during the manufacture of the paper.
- acidic dye, direct dyes or a mixture of dyes of the two classes mentioned and the cationic auxiliary are added to the paper stock and the paper stock is dewatered in the customary manner on a paper machine.
- the colored paper is then obtained directly.
- the order in which dyes or cationic auxiliaries are added to the paper stock is not decisive for the failure of the dyeings.
- the dyes in question and the cationic auxiliary can be added to the paper stock, and dyes first and then the cationic auxiliary added to the material, or the auxiliary and then the dyes added first.
- the cationic auxiliary is used in an amount of 10 to 300% by weight, preferably 30 to 150% by weight, based on the dye.
- the dyeing process can be carried out in a wide temperature range, e.g. B. from room temperature to about 60 ° C, preferably from 20 to 50 ° C.
- the paper can also be dyed according to the invention after sheet formation by successively applying the cationic auxiliary and one or more dyes in question to the surface of the paper, e.g. B. by spraying the auxiliary and then applying the dye in the size press. It is also possible to start with the paper in bulk one of the cationic auxiliaries and then apply a solution of the dyes in water in the size press. The dye can also be added to the mass and the cationic auxiliary agent can be applied in the size press. It is only important that the dyeing is carried out in combination with the cationic auxiliary. When drying paper dyed with acid dyes, the problem of color two-sidedness (cylinder two-sidedness) often occurs in practice.
- the process according to the invention gives dyeings with high color strength and practically uniform dyeings on the top and bottom of the paper formed.
- Another advantage over known processes is the fact that the process according to the invention, in particular in the case of acidic dyes, achieves substantially better retention of the dye than is the case with the known processes.
- the paper machine wastewater contains about half or less of unused dyes compared to paper machine wastewater from dyeing processes in which known aids are used.
- papers dyed in accordance with the invention have a high fastness to bleeding in contact with other materials, such as, for. B. papers, food, textiles in the presence of a wetting liquid such.
- the rating “none for a loss of color strength of 0 to 5% corresponds to the fact that color strength differences of this magnitude are difficult to perceive by the human eye and therefore play no role in practice.
- the ethylenimine modified polyamidoamine was benzylated by adding 192 parts of the 50.8% aqueous resin solution with 311 parts of water, heating to 80 ° C and within half an hour with 76 parts of benzyl chloride at a temperature in the range of 80 to 90 ° C brought together. After the addition of the benzyl chloride had ended, the reaction solution was heated to 90 ° C. for a further hour and then cooled. A 30.1% strength aqueous solution of a benzylated polyamidoamine grafted with ethyleneimine was obtained.
- a solution of 21 g of cyanamide in 21 g of distilled water was then added all at once to the reaction solution and the mixture was stirred at 90 ° C. for 5 hours.
- the aqueous solution was then diluted with 89 g of distilled water and 366 g of a 50% strength aqueous solution of a polyethyleneimine modified with benzyl chloride and cyanamide were obtained.
- the wet paper was dried between two absorbent papers on a 90 ° C cylinder with felt covering within 10 minutes without turning. Before drying, a 5 cm diameter plastic disc was placed on the side of the damp paper facing the felt. The coloration of the paper sheets provided a smooth color image and showed no two-sided cylinder.
- Example 1 is repeated with the exception that the absence of the cationic auxiliary is carried out. 95% of the dye used is then found in the draining water. The color of the paper is very weak, shows an unsteady color image and is very strong on both sides of the cylinder.
- Example 2 was repeated with the exception. that work was carried out in the absence of tool 1. 53% of the dye used was in the draining water. The color picture was calm. but showed a pronounced two-sided cylinder.
- Example 3 is repeated. however, work is carried out in the absence of tool 1. 18% of the dye used was in the draining water. The determination of the bleeding fastness according to DIN 53 991, sheet 1 resulted in the following values:
- Example 1 was repeated several times. however, instead of 0.33 g of auxiliary 1, the amounts of auxiliary given in table 1 and the other auxiliary also given in table 1 were used in the given amounts. Table 1 also shows the dye content in the waste water. based on the dyes used.
- Example 1 If Example 1 is repeated, except that the process is carried out in the absence of auxiliary 1, but as an auxiliary polyethyleneimine having a molecular weight of 1,500 or 860, the dye content in the wastewater roughly doubles compared to the auxiliaries used in Table 1. In contrast to the cationic auxiliaries to be used according to the invention, no further decisive improvement in dye retention occurs with the polyethyleneimines, even if these products are used in a larger amount.
- Example 1 is repeated with the exception that the auxiliaries indicated in Table 3 were used in the amounts indicated there.
- This example shows that when using the aids to be used according to the invention, a certain color strength of the paper sheet is achieved faster than when using known aids.
- the color strength of the colored paper was determined from its reflectance curve.
- the color strength obtained with the auxiliaries according to the invention at a certain concentration, based on the fiber used, is set to 100 in each case and compared with the color strength which is achieved when the corresponding precursor of the auxiliaries according to the invention which is not reacted with benzyl chloride is used.
- Example 1 If Example 1 is repeated, with the exception that auxiliaries 9 to 11 are used instead of the auxiliary 1 according to the invention, and alkylating agents which do not carry any aromatic groups have been used for their production, the wastewater of the laboratory sheet former contains significantly higher levels of dye than in Use of aids according to the invention. This becomes clear when the results from Table 1 are compared with Table 4.
