Claims (7)

  1. Wässrige hoch-feststoffhaltige Suspension eines teilchenförmigen Calciumcarbonatpigments für Papierbeschichtungszusammensetzungen, wobei das teilchenförmige Calciumcarbonatpigment eine spezifische Oberfläche hat, gemessen mit dem BET-N2-Verfahren, von weniger als 7,5 m2g-1 und eine Teilchengrößenverteilung, dass nicht mehr als 1 Gew.% der Teilchen einen Kugeläquivalenzdurchmesser (esd) größer als 10 µm haben, mindestens 65 Gew.% der Teilchen einen Kugeläquivalenzdurchmesser kleiner als 2 µm haben und nicht mehr als 10 Gew.% der Teilchen einen Kugeläquivalenzdurchmesser kleiner als 0,25 µm haben; und wobei das teilchenförmige Calciumcarbonatpigment kationisch dispergiert ist mit einem Dispersionsmittel, das eine Zusammensetzung aus einem kationischen Polyelektrolyten und einem anionischen Polyelektrolyten ist, wobei der kationische Polyelektrolyt in einer Menge verwendet wird, die ausreicht, die Pigmentteilchen kationisch zu machen.
  2. Wässrige hoch-feststoffhaltige Suspension nach Anspruch 1, dadurch gekennzeichnet, dass das Calciumcarbonatpigment eine spezifische Oberfläche im Bereich von 2.0 bis 6,5 m2g-1 hat, gemessen mit dem BET-N2-Verfahren.
  3. Wässrige hoch-feststoffhaltige Suspension nach Anspruch 1, dadurch gekennzeichnet, dass der kationische Elektrolyt in einer Menge verwendet wird im Bereich von etwa 0,01 bis 1,5 Gew.%, bezogen auf das Trockengewicht von Calciumcarbonat, und der anionische Polyelektrolyt in einer Menge verwendet wird, dass das Gewichtsverhältnis von kationischem Polyelektrolyt zu anionischem Polyelektrolyt im Bereich von etwa 2:1 bis etwa 20:1 ist.
  4. Wässrige hoch-feststoffhaltige Suspension nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, dass die wässrige Suspension vor oder nach der Dispersion des Calciumcarbonatpigments stark gemischt wird, damit der Suspension Energie zugeführt wird zwischen 10 und 50 kJ/kg Calciumcarbonat.
  5. Papierbeschichtungszusammensetzung mit einem Feststoffgehalt von mindestens 45 Gew.%, dadurch gekennzeichnet, dass sie eine hoch-feststoffhaltige wässrige Suspension nach Anspruch 1, 2, 3 oder 4 enthält und einen nicht-ionischen oder kationischen Klebstoff.
  6. Beschichtetes Papier, das eine Beschichtung einer Papierbeschichtungszusammensetzung nach Anspruch 5 enthält.
  7. Verfahren zur Papierherstellung, umfassend den Schritt des Wiederverwertens von beschichtetem Papier, das in eine faserförmige wiederverwertbare Form gebracht und dann in eine Papierherstellungszusammensetzung eingemischt wurde, dadurch gekennzeichnet, dass das beschichtete Papier ein Papier nach Anspruch 6 ist.
