Abstract (en)
[origin: EP2325389A1] Use of silicon dioxide-containing solid or a composition containing the solid as pigment or coating color for coating paper surfaces, is claimed, where the solid is present as an amorphous, non-crystalline solids and the solid or the composition produces paper with high gloss, high smoothness, high porosity, high opacity and high paper volume with low calender pressure or no calendering. Independent claims are included for: (1) making paper with high gloss, high smoothness, high porosity, high opacity and high paper volume, comprising applying the solid or the composition as a coating color on the paper and further processing the paper with low calender pressure or no calendering; and (2) a paper with a high gloss, high smoothness, high porosity, high opacity and high paper volume, obtained by the above process, where the paper comprises a surface coating, which includes the solid or the composition.
