| titleOfInvention | METHOD FOR IMPROVING OPPARITY |
| abstract | 1. A method of obtaining an aqueous suspension of dispersed calcium carbonate, providing improved optical properties of coatings obtained from it, comprising the steps of: a) providing an aqueous suspension of dispersed calcium carbonate; b) providing at least one alkali metal carbonate and / or alkaline acid carbonate a metal wherein the alkali metal ion is selected from potassium and / or sodium; c) diluting said aqueous suspension of dispersed calcium carbonate with water; and d) before and / or during and / or after step c) contacting said aqueous suspension of dispersed calcium carbonate with said at least one alkali metal carbonate and / or alkali metal acid carbonate. 2. The method according to claim 1, characterized in that the aqueous suspension of dispersed calcium carbonate provided in stage a) has a solids content of 35-85 wt.%, Preferably 65-80 wt.%, More preferably 68-78 wt.% And most preferably 70-78 wt.% with respect to the total weight of the aqueous suspension of dispersed calcium carbonate stage a). 3. The method according to claim 1, characterized in that at least one alkali metal carbonate and / or alkali metal acid carbonate is selected from the group consisting of sodium carbonate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate or mixtures thereof. . The method according to claim 3, characterized in that said at least one alkali metal carbonate and / or acidic alkali metal carbonate is sodium carbonate and / or potassium carbonate. The method according to claim 1, characterized in that the at least one alkali metal carbonate and / or alkali metal acid carbonate is introduced in quantities |
