AQUEOUS PIGMENT DISPERSIONS AND THEIR USE IN THE PRODUCTION OF FILLED PAPER |
摘要 |
Aqueous pigment slurries which contain up to 80 % by weight of a finely divided pigment in dispersed form and from 0.1 to 5 % by weight of a polyalkylenepolyamine having a molecular weight of at least 300 or water-soluble reaction products of (a) polyalkylenepolyamines having a molecular weight of at least 300 and/or polyamidoamines grafted with ethyleneimine and (b) bifunctional or polyfunctional crosslinking agents which have a halohydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as a functional group, the reaction products, in 25 % strength by weight aqueous solution at 20.degree.C, having a viscosity of at least 100 mPa.s, are used as an additive to the paper stock in the production of fillercontaining paper.
