    • 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.
    • 需要芳基丙酰苯胺磺酸颜料,即使当颜料含量相对较低时,通过常规印刷清漆稀释产生具有令人满意的流变特性的印刷油墨。 本发明涉及这样的糊状颜料制剂,其含有(a)5-50重量%的芳基拉罗沙宁磺酸颜料,(b)油含量基于油含量为70-80重量%的油含量为70-80重量%的长油醇酸树脂 与干燥,半干或不干燥的油或多种这些油的混合物或其二羧酸组分是间苯二甲酸和邻苯二甲酸的混合物的相应脂肪酸的反应,一小部分一种或多种α,β-不饱和的 二羧酸及其可能的酸酐,其多元醇成分含有甘油和季戊四醇的混合物,(c)平均分子量在600〜1700的烃树脂,其量为1-1.5倍 醇酸树脂b,(d)酚醛树脂改性松香树脂或环化橡胶树脂或两种树脂的组合,以及(e)矿物油。 制剂类似于由组分a,b,c和e组成的常规冲洗浆料,除了在冲洗过程中,在除去剩余的水之前或期间,加入组分d的树脂并加入其中。
