Abstract: Paper, board and cardboard are produced from paper stocks containing foreign sub- stances by drainage in the presence of a polymer which contains, as typical polymerized constituents, units of the formulae where R1 and R2 are each H, C1-C3-alkyl, and which have K values of not less than 130, the polymers containing less than 10 mol % of units of the formula II.

Abstract: The invention relates to a triarylmethane dye of formula (I), wherein R1 and R2 represent independently methyl, ethyl or hydroxyethyl, Q represents optionally substituted phenyl or naphthyl and A- represents the equivalent o f an anion. The triarylmethane dyes do not abstract any carcinogenic Michler's Keton.

Abstract: Paper, board and cardboard are produced by a process in which a paper stock is drained in the presence of condensates of basic amino acids with sheet formation. In particular, homo- and cocondensates of lysine and the crosslinked condensates obtainable therefrom by reaction with crosslinking agents are used in amounts of from 0.01 to 5% by weight, based on dry paper stock, as a means of increasing the dry and wet strength and the absorptivity of paper, for fixing anionic dyes and interfering substances in the paper, for increasing the drainage rate and the retention as well as the efficiency of synthetic anionic and cationic retention aids in the production of paper, board and cardboard by draining a paper stock with sheet formation.

Abstract: New cationic sulfonic acid dyes are bis(ammoniumalkyl-oxy-, -carbonyl, -carbonyloxy-, -carbonylimino-, -iminocarbonyl-phenylazo)-aminonaphtholsulfonic acid compounds giving fast dyeing for paper. New cationic sulfonic acid dyes are bis(ammoniumalkyl-oxy-, -carbonyl, -carbonyloxy-, -carbonylimino-, -iminocarbonyl-phenylazo)-aminonaphtholsulfonic acid compounds of formula (I); A , A = oxy, carbonyl, carbonyloxy, carbonylimino, iminocarbonyl, carbonyl-(1-4 carbon (C))-alkylimino or (1-4C)-alkyliminocarbonyl; B , B = 1-6 C alkylene, optionally with 1 or 2 non-adjacent oxy, imino or optionally hydroxy- (OH) or methoxy-(OMe) substituted 1-4C alkylimino groups in the chain; R = hydrogen (H) or 1-4C alkyl, optionally substituted by OH, OMe, chloro or phenyl; R = H or 1-4C alkyl; or NR R = 5-6-membered saturated heterocyclyl, optionally with another nitrogen (N) or oxygen (O) heteroatom; R , R = H, 1-4C alkyl (optionally substituted by OH, halogen or OMe), halogen, nitro or 1-4 C alkoxy; Q = H, 1-10C alkyl, optionally with 1-4 non-adjacent oxy, imino or optionally OH- or OMe-substituted 1-4 C alkylimino groups in the chain and optionally substituted by OH, halogen or phenyl; or NQ Q , NQ Q = 5-6-membered heterocyclyl, optionally with another N or O heteroatom; An = anion.

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.
