    摘要： The invention relates to using co-grinding agent in a method for producing co-ground in water GCC and PCC, wherein said agent is characterised in that a) it comprises at least one type of partially neutralised acrylic acid copolymer whose molar neutralisation degree is less than 75 % of the totality of acid functions and b) said agent is introducible during preparation of the GCC and PCC aqueous solutions and/or during co-grinding stage, and possibly between the co-grinding stage and a concentration stage and possibly during said concentration stage. The obtainable GCC and PCC aqueous solutions, dry GCC and PCC pigments and the use of said products in paper, paints, rubber and plastic material are also disclosed.
