荧光增白剂的水溶液
摘要：
组合物，其含有(A)按重量计算，总共占组合物(A)+(B)总量的2-30％的一种或多种式(1)的氨基醇其中R1、R2、R3和R4各自相互独立地是氢，C1-C12烷基，C5-C24芳基或C6-C36芳烷基，且R5和R6各自相互独立地是氢或C1-C4烷基；和(B)按重量计算，占组合物(A)+(B)总量的70-98％的式(2)的荧光增白剂其中X是氢、碱金属离子、铵离子或式(1)的氨基醇衍生的羟烷基铵基团，并且R7、R8、R9和R10各自相互独立地是-OR11、-NR11R12或下式的基团其中R11和R12各自相互独立地是氢、烷基、羟烷基、烷氧基烷基、羧基烷基、二羧基烷基、H2N-CO-烷基或烷硫基，其区别在于高水溶性和其水溶液的高储存稳定性。
摘要（英）：

Compositions comprising (A) a total of from 2 to 30 % by weight, based on the total composition (A) + (B), of one or more amino alcohols of formula (1) herein R1, R2, R3 and R4 are each independently of the others hydrogen, C1-C12alkyl, C5-C24aryl or C6-C36aralkyl, and R5 and R6 are each independently of the other hydrogen or C1-C4alkyl; and (B) from 70 to 98 % by weight, based on the total composition (A) + (B), of a fluorescent whitening agent of formula (2) herein X is hydrogen, an alkali metal ion, an ammonium ion or a hydroxyalkylammonium radical derived from the amino alcohol of formula(1), and R7, R8, R9 and R10 are each independently of the others -OR11, -NR11R12 or a group of formula (3) wherein R11, and R12 are each independently of the other hydrogen, alkyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl, dicarboxyalkyl, H2N-CO-alkyI or alkylthio, are distinguished by high solubility in water and by high storage stability of the aqueous solutions.
