摘要:
1. A method for producing self-binding pigment particles, comprising the following steps: a) providing an aqueous suspension of the mineral pigment material; b) providing at least one polymer binder, wherein said binder contains at least one modified polysaccharide having a degree carboxylation in the range from 0.4 to 2.0 and an intrinsic viscosity in the range from>; 300 to 500 ml / g; c) mixing the binder stage b) with an aqueous suspension of the mineral pigment material of stage a) and is regulated e the solids content of the resulting suspension, so that it is from ≥45 to 95% by weight (preferably 45 to 80% by weight) based on the total weight of the suspension; d) grinding the aqueous suspension of the mineral material of step c) .2 . The method of claim 1, wherein said at least one modified polysaccharide is carboxymethyl cellulose. The method of claim 1, wherein in step c), said binder is added to an aqueous suspension of a mineral pigment in an amount of from 0.1 to 10.0% by weight (preferably from 0.2 to 5% by weight, more preferably from 0 , 25 to 3.0% by weight) based on the total weight of the suspension. 4. The method according to any one of paragraphs. 1-3, where the specified binder is provided in the form of a solution or dry material, preferably in the form of an aqueous solution having a concentration of the binder from 0.5 to 50% by weight, preferably from 1 to 40% by weight, more preferably from 3 to 20% by weight and most preferably from 4 to 10% by weight, based on the total weight of the solution. 5. The method according to any one of paragraphs. 1-3, where the specified binder consists of at least only one modified�1. Способ получения самосвязывающихся пигментных частиц, включающий в себя следующие стадии:a) предоставление водной суспензии минерального пигментного материала;b) предоставление, по меньшей мере, одного полимерного связующего, где указанное связующее содержит, по меньшей мере, один модифицированный полисахарид, имеющий степен
