Abstract:
There is a demand for arylpararosanililinesulfonic acid pigments which, even when the pigment content is relatively low, produce on dilution with customary printing varnishes a printing ink having satisfactory rheological properties. The invention relates to such pasty pigment formulations containing (a) 5 to 50% by weight of an arylpararosanilinesulfonic acid pigment, (b) a long-oil alkyd resin having an oil content of 70-80% by weight whose oil content is based on the reaction with a drying, semidrying or nondrying oil or with a mixture of a plurality of these oils or with corresponding fatty acids whose dicarboxylic acid compontent is a mixture of isophthalic and orthophthalic acid, a small proportion of one or more alpha , beta -unsaturated dicarboxylic acids and, possibly, anhydrides thereof and whose polyalcohol component contains a mixture of glycerol and pentaerythritol, (c) a hydrocarbon resin having an average molecular weight within the range from 600 to 1700, the amount of which is 1-1.5 times that of alkyd resin b, (d) a phenolic resin modified colophony resin or a cyclized rubber resin or combinations of the two resins and also (e) mineral oil. The formulations are produced analogously to conventional flush pastes consisting of components a, b, c and e, except that in the flushing process, before or during the removal of the remaining water, the resin of component d is added and incorporated.
