Abstract
通式(I)的偶氮化合物,其中X代表卤素,尤其是氯,或C1-C4烷氧基,尤其是甲氧基,Y代表-CH2-或-O-,R1和R2各自独立地代表氢、C1-C8烷基,或最多可被C1-C8烷基、C1-C4烷氧基或卤素取代三次的C6-C14芳基,它们的制备方法,以及它们作为荧光化合物,尤其是作为固体荧光化合物,例如用于特殊效果印刷、证券印刷或在光电子领域中的用途。
Description
本发明涉及新颖的黄色和红色偶氮化合物,其制备方法,及其用作荧光化合物,尤其是作为固体荧光化合物的用途,例如对于特殊效果印刷、证券印刷(保密印刷)或在光电子领域中的应用。
颜料通过其物理特征,而不是通过化学组分与染料区别开。与颜料不同的是染料在施用期间溶解,并在使用中失去其晶体或颗粒结构。
一般基于有机染料的荧光着色剂代表一种重要的材料类型,这种材料常用于彩色印刷油墨、油漆和塑料中,以提供要求的颜色。这种着色剂往往称为工业荧光颜料,并通过将荧光染料溶解在诸如树脂基质的合适介质中获得。然后将这种树脂基质打碎成特定的尺寸,一般是几微米,以便可用作颜料。
有机颜料一般不表现出荧光,或其荧光仅有很低的强度。现有技术仅描述了有限数量的荧光有机颜料,例如W.Herbst和K.Hunger,Industrial Organic Pigments,第二版,VCH Verlagsgesellschaft,Weinheim,1997,571-572中描述的荧光C.I.颜料黄101。
与染料比较,颜料具有许多优点,例如它们具有良好的耐光性能或耐候性,而且没有转移问题。
因此,理想的是赋予有机颜料荧光,以便获得可在例如特殊效果印刷或证券印刷应用中得到应用的荧光有机颜料,以表现出颜料的物理特征固有的有益性能,从而代表对上述荧光染料的有益的选择。
US 5863459和5904878描述了通过首先分离作为干粉的合成颜料,然后将干颜料加入有机溶剂或水中得到浆料,并在加压下进行几个小时的热处理,以增强黄色和橙色二芳基化物颜料荧光的方法。当用分光光度计测量涂覆在基质上的油墨制剂的荧光时,通过现有技术的方法实现的光谱响应相对于未处理颜料而言最大约增加8%。在诸如乙醇的有机溶剂中处理颜料浆料实现的荧光强度的提高约为通过在水中处理实现的量的两倍。现有技术的缺点是在处理前不得不分离颜料,且要求用有机溶剂处理,以获得理想的结果。在恶劣条件下处理颜料被认为是另一个缺点。
因此一直需要一种荧光有机颜料,该颜料可通过直接的、容易操作的、没有现有技术的缺点的方法获得,且颜料尤其在固态下表现出高强度的荧光。
于是发现了通式(I)的所要求保护的颜料。此外也发现了其制备方法及其用途。
本发明涉及通式(I)的偶氮颜料
其中X代表卤素,尤其是氯,或C1-C4烷氧基,尤其是甲氧基,Y代表-CH2-或-O-,优选-O-,R1和R2各自独立地代表氢、C1-C8烷基,或最多可被C1-C8烷基、C1-C4烷氧基或卤素取代三次的C6-C14芳基,优选为C1-C8烷基,尤其是甲基,条件是如果R1和R2均为甲基且Y为-O-,则X不是甲氧基。
卤素指氟、氯、溴或碘,优选氯。C1-C8烷基指甲基、乙基、正丙基、异丙基、正丁基、异丁基、仲丁基、叔丁基、正戊基、异戊基、正己基、正庚基、正辛基、2-乙基己基,优选的是诸如甲基、乙基、正丙基、异丙基、正丁基、异丁基、仲丁基、叔丁基的C1-C4烷基;优选的是乙基,特别是甲基。

c)X为甲氧基,Y为-O-,R1和R2代表氢的偶氮化合物,
d)X为甲氧基,Y为-CH2-,R1和R2代表甲基的偶氮化合物。
偶氮颜料(I)的制备可采用常用的方式进行,没有具体限制。例如,将通式(II)的联苯胺衍生物
在-10℃-10℃温度范围内双偶氮化,制备双偶氮组分。通常将偶合组分,通式(III)的二酮
溶解在氢氧化钠水溶液中,其作为标尺,在加入双偶氮成分前调节到pH值低于7。偶合期间的温度一般保持在-5℃-50℃,优选的-2℃-20℃。然后通常将反应混合物加热0.1-2小时到5O-100℃。加热步骤后,用常用的方法,例如通过过滤,从反应混合物中分离出反应产物,任选用水清洗,除去可溶盐,然后干燥。同样优选的是将干燥产物研磨成粉或粒化。
可对通式(I)的新颖的偶氮颜料进行后处理,以改进其性能,例如它在油墨、油漆或塑料中的分散性。后处理方法是本领域普通技术人员公知的。
本发明另一个实施方案在于通式(I)的新颖的偶氮颜料
其中X代表卤素,尤其是氯,或C1-C4烷氧基,尤其是甲氧基,Y代表-CH2-或-O-,优选-O-,和R1和R2各自独立地代表氢、C1-C8烷基,或最多可被C1-C8烷基、C1-C4烷氧基或卤素取代三次的C6-C14芳基,优选为C1-C8烷基,尤其是甲基,
