用于纸涂层组合物的配方公开于,例如J.P.Casey“Pulp andPaper”中;Chemical and Chemical Technology,第2版,Volum III,第1684-1649页和“Pulp and Paper Manufacture”,第2版和第5版,Volum II,第497页(McGraw-Hill)中。

通过使用本发明方法,所得涂层有以下显著的特性:荧光增白剂在整个表面的分散有最佳的分布,并且因此增加了白色水平,对光和高温具高耐受性(如在60-100℃24小时稳定)并且对水有优异的耐渗性(bleed-fastness to water)。
在第二个优选方面,本发明提供将纸表面荧光增白的方法,该方法包括使纸以施胶压榨的方式与含有胶料,任选的无机或有机颜料和0.1至20g/l的式(1)的荧光增白剂的水溶液接触,优选地,胶料为淀粉,淀粉衍生物或合成施胶剂,特别是水溶性共聚物。
在第三个优选方面,上述定义的荧光增白剂对用于处理织物是特别重要的。纺织底物的处理在水性介质中进行有利,在该介质中具体的荧光增白剂以微细的形式(悬浮液,所谓微分散液和在某些情况下的溶液)存在。在处理过程中可以任选地加入分散剂,稳定剂,润湿剂和进一步的助剂。
处理通常在大约20-140℃的温度例如在热浴的沸点温度或者在其范围内(约90℃)进行。根据本发明,对于纺织品底物的整理,也可以用在有机溶剂中的溶液或乳液,就象在所谓溶剂染色中进行的染色(浸轧焙固法(pad-thermofix)和在染色仪中的尽染工艺(exhaustion dyeing process))中所使用的。
本发明中可使用的荧光增白剂也可以以例如以下形式使用:
(a)与所谓“载体”,润湿剂,软化剂,膨胀剂,抗氧化剂,光稳定剂,热稳定剂和化学漂白剂(亚氯酸盐漂白剂和漂白浴添加剂)的混合物。
(b)与交联剂和整理剂(例如淀粉和合成整理剂)的混合物并可结合各种织物整理工序,特别是合成树脂整理(例如抗皱整理例如“洗可穿”,“耐久压烫”和“免熨烫”),抗燃整理,柔软手感整理,防污整理或抗静电整理或抗微生物整理。
(c)作为各种肥皂和洗涤剂的添加剂。
(d)与其它具有荧光增白作用的物质合用。
如果荧光增白过程与织物处理或整理方法结合,结合处理可以在很多情况中优选籍助于相应的稳定制剂,该制剂含有在能够达到期望的增白效果的浓度中具有荧光增白作用的化合物。
在某些情况下,增白剂的全部效果可以通过后处理达到。这可以是,例如,化学处理(例如酸处理),热处理(例如加热)或混合化学/热处理。
本发明使用的荧光增白剂相对于被荧光增白的材料的用量,可以在宽范围内变动。用很少的量就能取得显著和持久的效果并且在某些情况下,例如只需要0.03%重量。但是,其用量也可以高达约0.5%重量。实际上在大多数令人感兴趣的情况下,相对于被荧光增白的材料,其量优选在0.05和0.5%重量之间。
在本发明的第四方面,荧光增白剂也特别适宜于作为洗涤浴或工业和家用洗涤剂的添加剂并且可以用多种方法加入。它们适宜以在水或有机溶剂中的溶液形式或以精细分散状态的水性分散体或浆液形式被加入洗涤浴中。它们,或它们的组分优选在洗涤剂生产的任何时期被加入工业或家用洗涤剂中,例如加至在喷雾干燥粉状洗涤剂之前的所谓“浆液”中或在液体洗涤剂混合物制备过程中加入。化合物可以以在水或其它溶剂中的溶液或分散液形式或在没有助剂时以干燥的增白剂粉末形式加入。但是,它们还可以以溶解或预分散形式喷洒到成品洗涤剂上。
可以使用的洗涤剂是已知的洗涤物质的混合物,例如碎片或粉末形式的肥皂,合成产品,磺酸的高级脂肪醇半酯的可溶性盐,被高级烷基取代和/或被烷基多取代芳基磺酸,与中等或高分子量醇的羧酸酯,脂肪酸酰氨基烷基-或氨基芳基-甘油磺酸酯,磷酸的脂肪醇酯等等。可以使用所谓“助洗剂”,例如多磷酸碱金属盐和聚偏磷酸碱金属盐,焦磷酸碱金属盐,羧乙基纤维素碱金属盐和其它“污垢再沉积抑制剂”,和硅酸碱金属盐,碳酸碱金属盐,硼酸碱金属盐,过硼酸碱金属盐,氨三乙酸,乙二胺-四乙酸和泡沫稳定剂,例如高级脂肪酸的链烷醇酰胺。而且,洗涤剂可以含有,例如:抗静电剂,富脂皮肤保护剂,例如羊毛脂,酶,抗微生物剂,香料和染料。
荧光增白剂具有特别的优点,它们也在活性氯供给体,例如,次氯酸盐存在下起作用并且可以在洗涤浴中与非离子洗涤剂例如烷基酚聚乙二醇醚一起使用而作用基本上不损失。该新增白剂在过硼酸盐或过酸和活化剂例如四乙酰基甘脲或乙二胺-四乙酸存在下在粉状洗涤剂和在洗涤浴中也是非常稳定的。
根据本发明的增白剂的加入量相对于液体或粉末状现成的洗涤剂重量的0.005至2%或更多,优选0.03至0.5%。当它们被用于纤维素纤维,聚酰胺纤维,高级整理的纤维素纤维,羊毛等等制造的纺织品的洗涤时,含有指定量的按照本发明的荧光增白剂的洗涤液使其在日光下具有光亮的外观。
洗涤处理可以例如如下进行:
将指定的纺织品在5至100℃且优选在25℃至100℃在洗涤浴中处理1至30分钟,该洗涤浴含有1至10g/kg含有助洗剂的复合洗涤剂和相对于洗涤剂重量的0.05至1%的权利要求的增白剂。浴比(liguor ratio)可以是1∶3至1∶50。洗涤后,将纺织品漂清并用常规方法干燥。洗涤浴可以含有作为漂白添加剂的0.2g/l活性氯(例如次氯酸盐形式)或0.1至2g/l过硼酸钠。
根据本发明的增白剂也可以于漂清浴与“载体”一起使用。为此,将增白剂掺入软性漂清剂或其它漂清剂中,其含有,作为“载体”,例如,聚乙烯醇,淀粉,共聚物,其以丙烯酸类为基础或甲醛/脲或亚乙基-脲或亚丙基-脲衍生物,其用量相对于漂清剂为0.005至5%或更多,优选0.2至2%。每升漂清浴中,含有本发明的增白剂的这类型漂清剂的用量为1至100ml,优选2至25ml时,能给各类处理后的纺织品提供光亮的增白效果。
在本发明的第五方面,式(1)化合物也适宜用于除去摄影材料中的污点,该材料包括卤化银摄影光敏感材料,更详细地,涉及其方法,其中改进在于防止在通过彩色显影剂和漂白固定浴生产所述卤化银摄影光敏材料的过程中引起的颜色污染,特别是颜色染料污染。
下列实施例用于举例说明本发明;份数和百分数用重量表示,除非另有说明。
