摘要： The application relates to a process for the preparation of pigment concentrates, preferably pulverulent pigment concentrates, which is characterized in that the polymer present in an intimate mixture, free from non-ionic surface-active agents, of an aqueous pigment suspension and an aqueous latex of a polymer or polycondensate containing carboxyl groups, or an aqueous solution of a polymer or polycondensate containing carboxyl groups, is coagulated by adding an electrolyte, while thoroughly mixing intensively, and the coagulate containing the pigment is then separated off in a known manner and optionally dried.The pigment concentrates are suitable for pigmenting aqueous media and printing pastes for pigment printing of textiles.
