    Abstract: The invention relates to readily storable flushed pastes of pigments of the arylparaosanilinesulfonic acid series, consisting essentially of (a) up to 50% by weight of the pigment, in a binder combination of (b) natural resin esters based on unmodified or modified natural resins with monohydric or polyhydric C1-C20-alcohols, and (c) long-oily alkyd resins having an oil content of 60% to 90% by weight dissolved in high-boiling mineral oil. These formulations are prepared from aqueous presscakes of pigment (a) by flushing in the presence of the solution of a mixture of at least one natural resin ester (b) and at least one alkyd resin (c) in mineral oil (d) with elimination of water. The novel pigment formulations are used for producing printing inks for letterpress and offset printing.
