1. An aqueous calcium carbonate containing composition comprising
a) a calcium carbonate containing material in an amount of at least 10 wt.-%, based on the total dry weight of the composition, b) at least one anionically charged comb polymer having a specific charge of −5 to −500 C/g at pH 8, c) optionally at least one binding agent in an amount of at least 2.5 wt.-%, based on the total dry weight of the composition, and d) at least one salt of a divalent or trivalent cation in an amount of between 1 and 20 wt.-%, based on the total dry weight of the composition, whereby at least 95 wt.-% of the total amount of salt is dissolved within the composition, and wherein the composition has a Brookfield viscosity of below 2500 mPa·s at 20° C. |
