Description
本发明涉及具有大的斯托克斯(Stokes)位移的荧光化合物及其制备方法。更具体而言,本发明涉及无色的荧光化合物。这些化合物可以用于油墨、油漆和塑料用组合物中,尤其是用于宽范围的印刷系统且特别适合安全应用。
相关技术说明
在UV光(365nm)下呈高度荧光的无色材料满足在标记和安全印刷(钞票、信用卡、身份证、护照等)中的重要工业需求。
已知大量属于苯并嗪酮衍生物类别的有机物质作为荧光材料的应用。尽管这样大量的已知化合物,但提供具有多元性能特点的产品通常存在困难。持续需要“无色”(即在电磁光谱的可见范围内具有最小吸收)并且同时满足工业稳定性要求(化学稳定性、热稳定性和/或光稳定性等)荧光颜料。
无色荧光材料的特殊应用领域涉及印刷方法用油墨,其用于印刷货币和其他安全文件,也称为“安全印刷”。典型的安全印刷方法是其中使用设计成在UV光(365nm)下在黄色至绿色光谱中发荧光,而在日光下无色的油墨组合物的方法。用于安全印刷的荧光颜料例如由“Honeywell International Inc.”得到,但它们基本全部在其坚牢度性能上弱。
EP0314350A1公开了式化合物,已经发现它们具有非常适合用于意欲标记安全文件的荧光油墨中的性能。R1、R2、R3和R4独立地为H、Z或Z取代的苯基;并且Ar为任选被Z取代的苯基或杂环基;其中Z独立地选自C1-4烷基、OH、C1-4烷氧基、卤素、NO2、NH2、 C1-4烷基氨基、二(C1-4烷基)氨基和苯基;条件是R1、R2、R3和R4在Ar为烷基苯基或烷氧基苯基时不全部为H。
US2006/00651154描述了芳基-脲基苯并嗪酮的合成。这些颜料在560nm至约585nm范围内的UV光下呈高度荧光,这使得它们可以在安全油墨中用作颜料。
WO2009045988A2提供了下式所示苯并嗪酮化合物: 其中R1、R2、R3和R4各自独立地选自氢、具有1-12个碳原子的烷基、取代的烷基、具有6-12个碳原子的芳基、取代的芳基、卤素和烷氧基;以及R5选自具有1-12个碳原子的烷基、取代的烷基、具有6-12个碳原子的芳基、取代的芳基、卤素和烷氧基;其中取代的烷基和取代的芳基各自具有选自烷基、芳基、卤素和烷氧基的取代基。此外,公开了具有苯并嗪酮化合物的标记、将该标记施加于制品上的方法以及制备苯并嗪酮化合物的方法。
现有技术中所述化合物可能显示出良好的耐光性。
然而,对于高端应用,现有技术中所述苯并嗪酮仍然需要在其坚牢度性能,例如耐溶剂性和耐碱(三乙胺)性上进行改进。这些性能对于安全印刷领域中的应用尤其重要。
现已惊人地发现某些苯并嗪酮化合物对化学品和溶剂呈现高耐受性而不丧失它们的其他优点如无色、良好的光稳定性和良好的热稳定性。它们可以有利地用作安全印刷,尤其是钞票的荧光颜料。

碱如吡啶也可以用作溶剂。
优选的溶剂是偶极非质子性溶剂,如单乙二醇二甲基醚(单甘醇二甲醚),二甘醇二甲基醚(二甘醇二甲醚),三甘醇二甲基醚(三甘醇二甲醚)和四甘醇二甲基醚(四甘醇二甲醚),二烷,二甲亚砜(DMSO),环丁砜,二甲基乙酰胺,1,3-二甲基咪唑啉-2-酮,N-甲基吡咯烷酮,苄腈,N,N-二甲基甲酰胺(DMF),四氢呋喃(THF)或乙腈。
优选将吡啶用作碱和溶剂,或者将三乙胺用作碱并将THF用作溶剂。若将吡啶用作碱和溶剂,则使用5-20份式II化合物、2.5-12份式III化合物和68-92.5份吡啶,其中式II化合物、式III化合物和吡啶的量加起来为100份。
该反应在0°C至该溶剂的回流温度的温度下,更优选在22-115°C下进行。非常特别优选40-50°C。
式II和III化合物或者市购或者可以经由本领域众所周知的合成方法制备。
1当量取代的邻氨基苯甲酸IV与1份邻氨基苯甲酰氯V缩合得到式II化合物。
式V化合物可以通过市售邻氨基苯甲酸衍生物与亚硫酰氯缩合而得到(使2当量邻氨基苯甲酸和3当量亚硫酰氯在12当量吡啶中反应)。
式I化合物也可以以包含至少一种式I化合物和至少一种不同于式I化合物的其他荧光化合物的混合物形式使用。合适的其他荧光化合物原则上是与式I化合物相容的所有已知类别的荧光化合物。合适的其他荧光化合物例如为香豆素类、茋类、苯并唑,苯并噻唑,苯并二唑,联吡啶衍生物,稀土金属配合物,无色无机荧光材料以及日光型荧光有机材料,例如苝类、呫吨类、马来酰亚胺类、萘二甲酰亚胺类、颜料黄101(=2,2’-二羟基萘甲醛连氮(2,2’-dihydroxynaphtaldazine)(Gelb S0790)), Irgazin Gelb GF(1,2,3,4-四氯苯并[4,5]咪唑并[2,1-a]异吲哚-11-酮)。
取决于所选择的应用,式I化合物通常可以以10ppm至25%,优选100ppm至10%的浓度使用。
式I化合物和荧光混合物尤其适合安全印刷。
安全印刷是涉及物品如货币、护照、防伪标签(tamper-evident label)、股票、邮票、身份证等的印刷的领域。安全印刷的主要目的是防止伪造、篡改或仿制。
在自动钞票处理领域中,荧光起着重要作用。大多数实际流通货币不仅带有可见的彩色印刷,而且带有仅通过用UV光辐照可检测的特殊特征。通常而言,这些荧光特征通过自动货币处理设备、在金融事务和贩卖应用(自动柜员机、自动售货机等)中进行利用,以识别确定的通货券(currency bill)并判定其真实性,尤其是将其与通过彩色复印机制造的复制品区分。
所有安全文件被要求具有良好的稳定性和耐久性。在钞票的情况下,这些要求是苛刻的,因为钞票经受公众的最激烈使用条件—它们因折叠、皱折等经受材料应力,经受磨耗,暴露于大气条件,暴露于体液如汗水,浆洗、干洗、熨烫等—并且在经受这之后预计像它们开始时那样清楚可见。此外,必要的是尽管遭受上述条件,但文件仍应具有合理的寿命,理想的是几年。在此期间,文件以及因此它们上面的油墨(包括不可见安全标记)应耐褪色或颜色变化。因此,任何用于安全印刷方法中的油墨在固化时应牢固、耐水、耐各种化学品且柔韧。此外,因为某些州禁止使用纸张作为钞票的基材,所以所用印刷油墨配制剂除了纸张外还应可用于塑料上。现已发现式I化合物由于其独特的应用性能而尤其适合用于安全印刷且尤其用于钞票的印刷油墨配制剂。
在安全印刷中,将式I化合物加入印刷油墨配制剂中。合适的印刷油墨是基于颜料或染料的水基、油基或溶剂基印刷油墨,用于喷墨印刷、柔性版印刷、丝网印刷、凹版印刷、胶版印刷、激光印刷或凸版印刷以及用于电摄影。用于这些印刷方法的印刷油墨通常包含溶剂、粘合剂以及还有各种添加剂,例如增塑剂、抗静电剂或蜡。用于胶版印刷和凸版印刷的印刷油墨通常配制成高粘度糊状印刷油墨,而用于柔性版印刷和凹版印刷的 印刷油墨通常配制成液体具有较低粘度的印刷油墨。
在本发明上下文中,表述“印刷油墨”也包括除了至少一种式I化合物外还包含着色剂的配制剂。表述“印刷油墨”也包括不包含着色剂的印刷漆。
本发明用于安全印刷的印刷油墨配制剂优选包含:
a)至少一种如上所定义的式I化合物,
b)聚合物粘合剂,
c)溶剂,
d)任选至少一种着色剂,和
e)任选至少一种其他添加剂。
印刷油墨的合适组分是常规的且对本领域熟练技术人员是众所周知的。该类组分的实例描述于“Printing Ink Manual”,第4版,Leach R.H.等(编辑),Van Nostrand Reinhold,Wokingham(1988)。印刷油墨及其配制剂的详情也公开于“Printing Inks”-Ullmann's Encyclopedia of Industrial Chemistry,第6版,1999年电子版中。红外线吸收性凹版油墨配制剂的配方描述于US20080241492A1中。上述文献的公开内容作为参考引入本文。

可以在本发明印刷油墨配制剂之前施加底漆。例如,可以施加底漆以改善与基材的粘附。还可以施加额外的印刷漆,例如以覆盖层形式施加,以保护印刷图像。还可以施加额外的印刷漆以用于美观目的,或用于控制与应用相关的性能。例如,可以使用适当配制的额外印刷漆来影响基材表面粗糙度、电气性能或水蒸气冷凝性能。印刷漆通常借助用于印刷本发明印刷油墨配制剂的印刷机上的上漆系统在线施加。
