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.
