The present invention relates to a method for preparing self-adhesive pigment particles, the method comprising the steps of: a) providing an aqueous mineral pigment material suspension; b) providing at least one polymeric binder, wherein the binder comprises at least one modified polysaccharide, The modified polysaccharide has a degree of carboxylation ranging from 0.4 to 2.0 and has an intrinsic viscosity ranging from >300 ml/g to 500 ml/g; c) mixing the binder of step b) with the aqueous mineral pigment material of step a), And adjusting the solid content of the obtained suspension so that the solid content is from 45% by weight to 95% by weight, preferably from 45% by weight to 80% by weight, based on the total weight of the suspension; and d) grinding step c) Aqueous mineral material suspension. |
