    • A process is disclosed for obtaining coating compositions of improved whiteness for coating paper or cardboard using fluorescent whitening agents of the bis-triazinylaminostilbene-2,2'-disulfonic acid series, which process comprises adding to the coating compositions, in addition to the respective fluorescent whitening agent, an acid phosphoric acid ester of an oxyalkylated fatty amine of the formula ##STR1## or an alkali metal salt, ammonium salt or amine salt thereof, wherein R is an aliphatic hydrocarbon radical of 8 to 22 carbon atoms, Y.sub.1 and Y.sub.2 are both hydrogen, or one of Y.sub.1 and Y.sub.2 is hydrogen and the other is methyl, X is the acid radical of phosphoric acid, the acid hydrogen atoms of which radical can be replaced by alkali metal ions, ammonium ions or amine salt ions, and m and n are integers, the sum of which is 2 to 30. To the coating compositions can also be added organic solubilizers, non-ionic or anionic surfactants and/or polar organic compounds. Coating compositions which contain the above fluorescent whitening agents and assistants are also disclosed.
    • 公开了一种用于获得使用双 - 三嗪基氨基芪-2,2'-二磺酸系列的荧光增白剂涂布纸或纸板的改善白度的涂料组合物的方法,该方法包括向各涂料组合物中加入除了各自的荧光 增白剂,式(1)的烷氧基​​化脂肪胺的酸式磷酸酯或其碱金属盐,铵盐或胺盐,其中R是8-22个碳原子的脂族烃基,Y1 和Y2都是氢,Y1和Y2之一是氢,另一个是甲基,X是磷酸的酸基,其自由基的酸性氢原子可以被碱金属离子,铵离子或胺盐离子代替 ,m和n为整数,其总和为2至30.对于涂料组合物,还可以加入有机增溶剂,非离子或阴离子表面活性剂和/或极性有机化合物。 还公开了含有上述荧光增白剂和助剂的涂料组合物。
