Abstract: The invention relates to a method of producing paper, paperboard and cardboa rd by dewatering a paper material in the presence of condensation products of basic amino acids and sheet forming. The inventive method especially uses ho mo- and co-condensation products of lysine and the cross-linked condensation products obtained therefrom by reaction with cross-linking agents in an amou nt of from 0.01 to 5 wt.- % based on the dry paper material to increase the dry and wet strength and the absorbency of paper. These materials are also used to fixate anionic dyes and interfering substances in the paper, to increase the dewatering rate and the retention and the efficacy of synthetic anionic and cationic retention agents in the production of paper, paperboard and cardboa rd by dewatering the paper material and sheet forming.

Abstract: Recovery of pigments from the waste water from paper coating operations comprises adding a water-soluble condensation product of dicyandiamide, HCHO, ammonium salts and optionally also urea so as to give a pigment-containing precipitate and then separating off the precipitate and re-dispersing it in water in the presence of a base.

Abstract: Paper, board and cardboard are produced from paper stocks which contain tacky impurities by the addition of surfactants and cationic polymers having a charge density of at least 1.5 meq/g (measured at pH 7) and a molar mass Mw of the cationic polymers of at least 15,000 and drainage of the paper stocks with fixation of the tacky impurities in the paper produced.
