    摘要: A water soluble ethylenic copolymer-based dispersant for water-based pigment compounds, comprising a liquid phase, a binder which is an emulsion polymer, especially without protective colloids and which contains a considerable density of anionic groups, of pigments wholly or partially reactive with regard to their medium by the creation of bonds between the particles of emulsion polymer and the metallic ion of the partially soluble reactive pigment, characterized by the fact that in order to confer on such water-based pigment compounds definable rheological characteristics, which can be adjusted in advance and remain stable over periods of time, the said water soluble dispersant is an acrylic, methacrylic and itaconic acid copolymer.

    摘要: Complex pigment compositions for the coating of paper, comprising an aqueous phase, at least one pigment of mineral origin, a binding agent, optionally various customary additives, and a dispersing agent comprised of carboxyl-containing polymers which are water soluble and are converted to form salts. The polymers are obtained by known polymerization processes. The dispersing agent(a) has a specific viscosity (measured on the sodium salt) of between 0.25 and 2; and(b) is converted to the salt form to the extent of at least 60% by at least one salt-forming agent which has a polyvalent function.These complex pigment compositions have very low viscosities. They may also simultaneously contain diverse pigments, such as kaolin, titanium dioxode, and calcium carbonate, without suffering the usual increase in viscosity and the risk of setting.
