Description
GB-A-2 200 600、EP-A-238 446、EP-A-321393、DE-A-4 219 772和PCT/EP 94/02914已公开了基于双苯乙烯基化合物的萤光增白剂的混合物。
本发明的目的是提供新的基于双苯乙烯基化合物的增白剂混合物,此增白剂混合物应是用简单方法获得及具有便于应用的特点,特别是高度增白。
我们已发现本发明的目的可由特别在本文开始叙述的增白剂混合物达到。
新的增白剂混合物——基于混合物重量的每种情况——含75%-100%重量、优选80%-100%重量、最优选85%-100%重量分子式I-V的双苯乙烯基化合物。
工业上特别感兴趣的增白剂混合物含——基于混合物重量——85%-90%重量分子式I-V的双苯乙烯基化合物。
剩余部分,本发明的增白剂混合物可有代表性地另外含有例如分子式VI的化合物及其盐
本发明的增白剂混合物优选含有——基于分子式I-V的双苯乙烯基化合物的总重量——30%-45%重量分子式I的双苯乙烯基化合物、40%-50%重量分子式II的双苯乙烯基化合物、0.5%-5%重量、优选1%-3.5%重量分子式III的双苯乙烯基化合物,及另外1%-15%重量、优选5%-15%重量分子式IV双苯乙烯基化合物和/或1%-15%重量、优选5%-15%重量分子式V的双苯乙烯基化合物。
新的增白剂混合物能由例如混合适当重量比的各个组份制备。各个组份能用常规方法获得,例如在惰性有机稀释剂中,在碱性介质中用对苯二醛和烷基氰基膦酸酯反应。
本发明进一步提供的增白剂配方含有水和——在基于配方重量的拇种情况——3%-25%重量、优选5%-15%重量上述定义的增白剂混合物以及5%-60%重量、优选5%-52%重量助剂。
适用的助剂包括,例如环氧乙烷和脂肪醇的加合物,高级脂肪酸或烷基酚或乙二胺-环氧乙烷-环氧丙烷加合物类的阴离子或非离子分散剂,或者如DE-4-2745449中所述的分散剂,N-乙烯基吡咯烷酮和3-乙烯基丙酸的共聚物,水助留剂,如乙二醇、丙三醇或山梨糖醇,或杀菌剂。
优选的增白剂配方,除水外,含——基于配方重量的每种情况——3%-25%重量、优选5%-15%重量上述定义的增白剂混合物,3%-12%重量阴离子或非离子分散剂,1%-15%重量N-乙烯基吡咯烷酮和3-乙烯基丙酸的共聚物和1%-25%重量其它助剂(例如,水助留剂或杀菌剂)。
本发明的增白剂混合物便于用作合成或天然聚合材料、特别是聚酯的萤光增白。聚酯是呈纺织品形式。其意思可理解为,特别是纤维、纱、线、编织物、纺织物或无纺织物。新的增白剂混合物结合了低固定或排气温度和便于应用的特性。它们也是高产的。新的增白剂混合物的进一步的优点是它们能在高温下,特别在200-220℃下很好使用。
