    Abstract: PROBLEM TO BE SOLVED: To obtain a new cationic sulfonic acid dyestuff excellent in dyeing and printing of a polymeric material, especially a paper. SOLUTION: This cationic sulfonic acid dyestuff is a dyestuff of formula I [A1, A2 are each oxy, carbonyl, a carbonyl-(1-4C alkylimino) or the like; B1, B2 are each an alkylene; R1 is H or a (substituted) 1-4C alkyl; R2 is H, a 1-4C alkyl or the like; R3, R4 are each H, a (substituted) alkyl or the like; Q1 to Q6 are each H, 1-4 non adjacent oxys, imino or the like; An is an anion], e.g. a compound of formula II. The dyestuff of formula I is obtained by diazotizing an amine of formula III, and reacting the obtained product with a coupling component of formula IV preferably at pH 3-5.

    Abstract: PROBLEM TO BE SOLVED: To obtain a new dyestuff consisting of a specific cationic azo dyestuff, useful for dyeing and printing of polymeric materials, and having characteristics such as an excellent light fastness, a high color depth and an affinity to fibers. SOLUTION: This aminobenzoic acid cationic dyestuff is a compound of formula I [(n) is 0-8; R1 is H, a 1-6C alkyl or the like; R2, R3 are each H, a 1-6C alkyl or the like; K is a group of a coupling component; A is oxy, imino or a (substituted) 1-6C alkylimino; B is 1-2 non-adjacent oxys or the like; Q1 to Q3 are each H, 1-4 non-adjacent oxys, imino or the like; An is an anion], e.g. 6,6'-diamino bis(2-dimethylaminoethyl)-3,3'-methylenebis benzoate. To obtain the dyestuff of formula I, an amine of formula II is diazotized and the product is coupled with a coupling component KH.

    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: The invention relates to cationic azo-dyes of the general formula (I), in which R and R independently of each other are hydrogen, nitro, halogen, C1-C6-alkyl; R is hydrogen, C1-C6-alkyl, which can be interrupted by 1 or 2 non-adjoining oxy-, imino- or C1-C6-alkylimino groups or a rest (II); A and A independently of each other are oxy, imino or possibly substituted C1-C6-alkylimino; B and B independently of each other are C1-C6-alkylene, which can be interrupted by 1 or 2 non-adjoining oxy-, imino- or possibly substituted C1-C6-alkylimino groups or a rest (II); An is the equivalent of an anion; n is a number between 1 and 8; and K is the rest of a coupling component or a monoazo-dye II. The invention also relates to a method for producing said dyes, to their use for colouring and printing on natural or synthetic substrates and to mixtures thereof.
