Zusammenfassung:A mineral composition comprising mineral particles, said mineral particles, when in a densely compacted bed form, having a volume defined median pore diameter from 0.01 to 0.04 micrometre, and having an intruded total specific void volume of 0.1-0.3 cm 3 /g. A specific advantage of this composition is that it as a component in a coating, allows the passage of ink solvent into the base paper while retaining the ink molecules on the surface.
