Description
本发明涉及新型二氨基嘧啶分散偶氮染料、制备这样的染料的方法及其在半合成,尤其是合成疏水纤维材料,更尤其是纺织材料的染色或印刷中的用途。
二氨基嘧啶分散偶氮染料是例如从英国专利1 418 742中已知的。但是,已经发现,使用目前已知的染料获得的染色品(dyeings)或印刷品(prints)并非在所有情况下都满足现今的要求,尤其是在耐光牢度方面。因此需要尤其具有良好耐光牢度性质的新染料。
令人惊讶地,我们发现,被含氮的杂环芳环取代的二氨基嘧啶分散偶氮染料满足上述要求并表现出极好的耐光牢度,尤其是热耐光牢度。

其中

式(2a)或(3a)的胺化合物的重氮化以本身已知的方式进行,例如在酸性(例如含盐酸或含硫酸)水性介质中用亚硝酸钠进行。但是,重氮化也可使用其它重氮化剂,例如用亚硝酰硫酸进行。在重氮化中,在反应介质中可存在另外的酸,例如磷酸、硫酸、乙酸、丙酸或盐酸或这样的酸的混合物,例如丙酸和乙酸的混合物。重氮化有利地在-10至30℃,例如-10℃至室温的温度下进行。
式(2a)或(3a)的重氮化化合物与式(1a)的偶联组分的偶联同样以已知方式,例如在酸性、水性或水性-有机介质中,有利地在-10至30℃,尤其低于10℃的温度下实现。所用的酸的实例是盐酸、乙酸、丙酸、硫酸和磷酸。
式(2a)或(3a)的化合物是已知的或可以本身已知的方式制备。式(1a)的偶联组分的前体是已知的或可以本身已知的方式制备,例如如Synthesis 2010, 第7期, 第1091-1096页(2010)中所述。
式(1a)的偶联组分是新型的。相应地,本发明也涉及下式的化合物
其中
R1、R2和X如上文定义,其可例如用作用于制备分散偶氮染料的偶联组分。在实验部分中描述了该制备。
根据本发明的染料可用于半合成,尤其是合成疏水纤维材料,更尤其是纺织材料的染色或印刷。由包含这样的半合成或合成疏水纤维材料的混纺织物组成的纺织材料也可使用根据本发明的染料染色或印刷。
考虑的半合成纤维材料尤其是纤维素21/2-乙酸酯和三乙酸纤维素。
合成疏水纤维材料尤其由线性芳族聚酯,例如对苯二甲酸和二醇,尤其是乙二醇的聚酯,或对苯二甲酸和1,4-双(羟甲基)环己烷的缩合产物;聚碳酸酯,例如α,α-二甲基-4,4-二羟基-二苯甲烷和光气的聚碳酸酯,和基于聚氯乙烯或基于聚酰胺的纤维组成。
根据已知染色方法实现将根据本发明的染料施加到纤维材料上。例如,将聚酯纤维材料在浸染(exhaust)法中由存在常规阴离子或非离子分散剂和任选地,常规溶胀剂(载体)的水性分散体在80至140℃的温度下染色。纤维素21/2-乙酸酯优选在65至85℃下染色,且三乙酸纤维素在65至115℃的温度下染色。
根据本发明的染料不会将同时存在于染浴中的羊毛和棉着色或仅轻微地将这样的材料着色(极好的防染性(reservation)),因此它们也可令人满意地用于聚酯/羊毛和聚酯/纤维素纤维混纺织物的染色。
根据本发明的染料适用于根据热溶胶法染色、在浸染法中染色和用于印刷法。
在这样的方法中,所述纤维材料可以是各种加工形式,例如纤维、纱线或非织造物、机织织物或针织织物的形式。
有利的是在使用前将根据本发明的染料转化成染料制备物。为此,研磨该染料以使其粒度为平均0.1至10微米。可在分散剂存在下进行研磨。例如,将干燥染料与分散剂一起研磨或与分散剂一起捏合成糊料形式,然后在真空中或通过雾化干燥。在加入水后,所得制备物可用于制备印刷膏和染浴。
对于印刷,使用常规增稠剂,例如改性或未改性天然产品,例如藻酸盐、糊精(British gum)、阿拉伯树胶、结晶树胶、刺槐豆粉、黄蓍胶、羧甲基纤维素、羟乙基纤维素、淀粉或合成产品,例如聚丙烯酰胺、聚丙烯酸或其共聚物,或聚乙烯醇。
根据本发明的式(1)的染料也适合作为记录系统中所用的着色剂。这样的记录系统是例如用于纸或织物印刷的市售喷墨印刷机,或书写工具,如钢笔或圆珠笔,尤其是喷墨印刷机。为此,首先将根据本发明的染料制成适用于记录系统的形式。合适的形式是例如包含根据本发明的染料作为着色剂的水性墨水。该墨水可以常规方式制备——通过在所需量的水中将各个组分混合在一起,如果必要,与合适的分散剂组合。
根据本发明的染料为所述材料,尤其是聚酯材料赋予具有极好的使用牢度性质,尤其例如良好的耐光牢度、耐热定型牢度、耐褶裥牢度、耐氯牢度和耐湿牢度,例如耐水、耐汗和耐洗牢度的均匀色调;完成的染色品进一步以极好的耐摩擦牢度为特征。应该特别强调所得染色品对光的良好牢度性质。
此外,根据本发明的染料和染料混合物也非常适合由超临界CO2将疏水纤维材料染色。
本发明涉及根据本发明的染料的上述用途以及半合成或合成疏水纤维材料,尤其是纺织材料的染色或印刷方法,在所述方法中将根据本发明的染料施加到所述材料上或并入其中。所述疏水纤维材料优选是纺织聚酯材料。在上文中的根据本发明的染料的用途的更详细描述中可找到可通过本发明的方法和优选工艺条件处理的其它基底。
在喷墨印刷法的情况下,将独立墨滴以受控方式从喷嘴喷射到基底上。连续喷墨法和按需喷墨法主要用于此用途。在连续喷墨法的情况下,连续产生液滴,将印刷操作不需要的液滴排放到容器中并回收。另一方面,在按需喷墨法的情况下,按需生成液滴并用于印刷;也就是说,仅在印刷操作需要时才生成液滴。液滴的产生可以例如借助压电喷墨头或通过热能(气泡喷射)实现。优选借助压电喷墨头印刷和根据连续喷墨法印刷。
本发明因此还涉及包含根据本发明的式(1)的染料的水性墨水和这样的墨水在用于印刷各种基底,尤其是纺织纤维材料的喷墨印刷法中的用途,上文指出的定义和优选项适用于染料、墨水和基底。
本发明还涉及通过所述方法染色或印刷的疏水纤维材料,优选聚酯纺织材料。
根据本发明的染料还适用于现代复制法,例如热转印。
下列实施例用于举例说明本发明。除非另行指明,其中的份数是重量份且百分比是重量百分比。温度以摄氏度给出。重量份和体积份之间的关系与克和立方厘米之间的关系一样。

下表中所列的制备实施例2至114的染料可类似于上述制备实施例1制备。
II.应用实施例
应用实施例1:
将1重量份根据制备实施例1的式(101)的染料与4份市售分散剂和15份水一起研磨。使用这种配制物,通过在135℃下的高温浸染法在织造聚酯上产生1%染色(基于染料和基底计)。
试验结果: 该染色品的耐光牢度以及在VDA 75202 5循环和SAE J2412 488 kJ试验中的结果优异。该染料的提升(build-up)性质非常好。
应用实施例2至114:
使用制备实施例2至114的染料代替根据制备实施例1的式(101)的染料重复应用实施例1。这些染料的提升性质非常好并且染色品表现出良好的耐光牢度以及在VDA 752025循环和SAE J2412 488 kJ试验中的极好结果。
对比例
使用GB 1418742中公开的染料重复应用实施例1。GB 1418742中公开的染料对应于取代的二氨基嘧啶分散偶氮染料,但GB 1418742没有公开用含氮的杂环芳环取代的二氨基嘧啶分散偶氮染料。GB 1418742 中公开的并用于这一对比例1和对比例2的染料的实例符合以下结构:
对比例1
对比例2
将使用根据GB 1418742的染料获得的在热-光暴露后的耐光牢度和颜色变化与使用根据应用实施例22和应用实施例24的染料获得的耐光牢度进行比较:
应用实施例22
应用实施例24。
下面概括根据SAE J2412 488 kJ标准获得的结果:
提升率(RD) | 暴露后的颜色强度(%) | 暴露后的颜色变化dE<sub>ab*</sub> | |
对比例1 | 0.25 | 74 | 6.33 |
应用实施例22 | 0.25 | 77 | 4.92 |
对比例2 | 0.25 | 61 | 10.66 |
应用实施例24 | 0.25 | 69 | 8.42 |
使用根据本发明的染料(对应于制备实施例22)在根据SAE J2412 488 kJ试验的热-光暴露后的颜色强度损失略好于使用根据GB 1418742的染料的颜色强度损失。
根据以下公式计算颜色变化(dEab*或简写形式为dE*):
其中
a*、b*= 颜色坐标
da*、db* = 颜色坐标差异
L*= 亮度
dL* = 亮度变化。
使用根据本发明的染料(对应于制备实施例22)在根据SAE J2412 488 kJ试验的热-光暴露后的颜色变化明显好于使用根据GB 1418742的染料的颜色变色。这一令人惊讶的结果归因于在根据本发明的染料中存在取代的含氮杂环芳环。
