It was found that it can be perfectly obtained. dispersed and stable aqueous pigment pastes, which are pigment suspensions in sodium thiocyanate solution, are used c as dispersant, acrylonitrile copolymers commonly used in the production of polyacrylonitrile fibers. The acrylonitrile comonomers in the copolymers used according to the invention and in the production of polyacrylonitrile fiber are methyl acrylate, methyl methacrylate, itaconic acid, vinyl acetate, the content of acrylonitrile in the copolymer must not be less than 92% by weight. 5-15% by weight of one of the abovementioned acrylonitrile copolymers as a solution in an aqueous 50-65% sodium rhodate solution is added to the freshly precipitated pigment which is sucked off the mother liquor. shorten the consistency of the paste best suited to the type of grinding equipment used, in which the grinding is carried out to obtain pigment particles with a diameter of 1 micron. After the grinding process and possible separation of particles with the largest diameter in separators, it is possible to dilute the pigment paste accordingly by additionally introducing the acrylonitrile copolymer solution I live in sodium chloride. The concentration of the aqueous sodium rhodate solution in the final product should not be less than 30% by weight and the amount of copolymer should not be less than 5% by weight. This prevents agglomeration of pigment particles during transport and storage and is especially recommended for pigment pastes intended for longer storage. The use of acrylonitrile copolymers as dispersants ensures, apart from a perfect and stable dispersion of the aqueous pigment paste, good quality unchanged by the dyeing process. Fibers.
