Abstract: The invention concerns aqueous pigment slurries containing, dispersed in them, up to 80% by wt. of a finely particulate pigment and 0.1 to 5% by wt. of dispersants. Such slurries are obtained by reacting (a) polyalkylene polyamines, polyamidoamines, ethylenimine-grafted polyamidoamines, polyether amines or mixtures of these compounds with (b) momoethylenically unsaturated carboxylic acids, salts, esters, amides or nitriles of monoethylenically unsaturated carboxylic acids, chlorocarboxylic acids and/or glycidyl compounds and optionally with (c) at least bifunctional cross-linking agents containing as the functional group a halohydrin, glycidyl, aziridin or isocyanate unit or a halogen atom to give water-soluable condensation products which have a viscosity, measured at 20.degree.C in 20% by wt. aqueous solution, of at least mPas. The invention also concerns a method of producing such aqueous pigment slurries by grinding or otherwise dispersing the pigments in the presence of the dispersants and water, and the use of the aqueous pigment slurries as additives to paper pulp in the manufacture of paper containing fillers.

Abstract: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.

Abstract: The present invention relates to starch which is modified with at least one cationic polymer(P), and a method for producing same which is characterized in that: a) an anionically modified starch (A) is reacted with the cationic polymer (P); or that (b) a native starch (B) or a non-anionically modified starch (C) is reacted with the cationic polymer (P) in the presence of an anionic modifier (M). The invention also relates to the use of said polymer-modified starches.
