ABSTRACT:
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.
