Abstract

Suspensión acuosa que proporciona una elevada opacidad al papel. Comprende sulfato cálcico y al menos un aditivo. También se refiere a un procedimiento para la preparación de dicha suspensión acuosa y a un procedimiento de preparación de papel donde dicha suspensión acuosa se adiciona a la suspensión de fibras celulósicas. La adición de dicha suspensión acuosa a la pasta de fibras celulósicas en el procedimiento de preparación del papel provoca un aumento sorprendente de la capacidad opacificante del sulfato cálcico.
