The reaction mixture was heated so that the water which was originally added and which formed on condensation distilled off. A bottom temperature of 170 ° C. was reached within 5 hours while continuously distilling off the water. This temperature was maintained until the resin had an acid number of less than 10 (about 10 hours at 170 ° C).

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% aqueous solution of a benzylated polyamidoamine grafted with ethyleneimine was obtained.

The color image of the paper was calm, but the two-sidedness of the paper was clearly pronounced.
  • 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 image was calm, but showed a pronounced two-sided cylinder.
  • Example 3 is repeated, but the procedure 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, but instead of 0.33 g of aid 1, the amounts of aid indicated in table 1 and the other auxiliaries likewise indicated in table 1 were used in the amounts indicated. 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 1500 or 860, the dye content in the wastewater roughly doubles compared to the auxiliary materials 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 the aids to be used according to the invention are used, a certain color strength of the paper sheet is achieved more quickly. * is sufficient 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 with a comparison of the results from Table 1 with Table 5.
