ABSTRACT:
The deliveries to the printing ink industry of pigment preparations in the form of flushed pastes increasingly take the form of containers. Given the required high pigment content of the pastes and the attendant high viscosity and thixotropy, there are very frequent problems with filling the containers and complaints concerning the emptying of the containers. There is a demand for a homogeneous, pumpable pigment paste having a long shelf life. According to the invention, this demand is met in the case of pigments based on arylpararosanillnesulfonic acids by the use of specific aids of the type of the condensation products of aliphatic amines or ammonium compounds with polyesters of hydroxy fatty acids as part of the flushing process of the pigment using the customary or slightly modified binder systems which for the same pigment contents bring about a distinctly lower viscosity and thixotropy. The printing properties are not adversely affected.
