Abstract: Paper, pasteboard and cardboard (I) are produced by draining off pulp contg. interfering substances in the presence of fixing agents (II) and cationic retention agents; the novelty is that (II) are hydrolysed homo- and/or co-polymers of N-vinylformamide (III) with degree of hydrolysis (DH) at least. 60%. (II) has DH 70-100%; (II) are hydrolysed copolymers of (III) and up to 90 mol.% unsatd. comonomers, namely vinyl acetate or propionate, 1-4C alkyl vinyl ether, N-vinyl-pyrrolidone, or esters, nitriles or amides of (meth)acrylic acid, with DH = 70-100%; pref. (II) are obtd. by polymerisation of 100-10 mol.% (III) and 0-90 mol.% vinyl acetate and/or propionate, followed by cleavage of 60-100% of the formyl gps., and 60-100% of the acetyl and/or propionyl gps.

Abstract: Aqueous pigment suspensions which are added to the stock suspension during papermaking and contain, as a dispersant, from 0.1 to 2% by weight, based on the pigment, of a copolymer which contains, as copolymerized units, (a) from 40 to 95% by weight of an ester of (meth)acrylic acid with a saturated monohydric C1-C8-alcohol or with a saturated dihydric C2-C4-alcohol and (b) from 60 to 5% by weight of an ethylenically unsaturated C3-C5-carboxylic acid and has a K value of from 10 to 65 (determined according to H. Fikentscher in 1% aqueous solution in the form of the ammonium salt at pH 9 and at 20 DEG C.), their preparation and their use.

Abstract: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.

Abstract: Process for improving the printability of paper by a single- or two-sided application of aqueous coating materials consisting of a) 100 parts by weight of a finely dispersed pigment b) 5 to 70 parts by weight (based on solids) of a cationic aqueous polymer dispersion of a paper size and c) 0.01 to 10 parts by weight of a surfactant which interferes with the formation of the surface sizing and/or of a polymeric dispersant to the surface of the paper in a quantity of 0.5 to 4 g/m and drying the coated paper.
