ABSTRACT:
The invention relates to pasty pigment formulations of pigments of the arylpararosanilinesulfonic acid series, which are free of aromatics-containing mineral oils and are suitable for preparing printing inks, in particular letterpress and offset printing inks. The pigment formulations are obtainable by flushing aqueous presscakes of the pigments by means of the solution of a flushing resin in aromatics-free mineral oil and preparing the flushed paste obtained with an oil- or fatty-acid modified alkyd resin.
