Abstract (en)
[origin: EP0307795A2] A cationically modified pigment dispersion which is particularly suitable for the manufacture of coating colours for paper coating contains: (a) a pigment component consisting of calcium sulphate, talc and/or aluminium hydroxide or containing these as the main constituent or extender (b) a cationic polymer or a quaternary ammonium compound as dispersant and/or (c) a cationic polymer which surrounds as a protective colloid the particles of the pigment component (a) and has been obtained from hydrophilic polyacrylates or polymethacrylates, degraded starches or degraded modified starches, degraded galactomannans or degraded modified galactomannans, methylcelluloses, hydroxymethylcelluloses, carboxymethylcelluloses, degraded alginates, proteins and/or polyvinyl alcohol.
