该新染料也可以用于制备适用于喷墨印刷法的印刷油墨。
将用下列实施例说明本发明。在实施例中,除非特别指明,份和百分含量均用重量表示,并且所有给定的温度均指摄氏度。
实施例1
在搅拌条件下,将497份2-氨基-5-(2’-硫酸根合乙基磺酰基)苯磺酸放进1500份水中,并且通过加入约600份冰将紫色悬浮液冷却到约0℃-5℃。在该温度下滴加约190份40%的亚硝酸钠溶液,并且同时将319份1-氨基-8-羟基萘-3,6-二磺酸悬浮在1000份水中。将该悬浮液与第一种重氮悬浮液混合并且通过加入约1250份15%碳酸钠溶液使pH值升高到3-4。
单独地,将由2,4-二氨基苯磺酸和2,4,6-三氟嘧啶得到的332份缩合产物重氮化,并且将该第二种重氮悬浮液加入到单偶氮染料悬浮液中。通过加入约75份15%的碳酸钠溶液进一步将pH值升高到6-8,并且将得到的溶液喷雾干燥。得到约2000份可将纤维素纤维染为深海军蓝色的含有蓝黑色盐的粉末。该染料用下式表示
并且该染色物具有极好的耐褪色性,因此即便是深染物,非固定染料也很容易被洗掉。
实施例2
如果将在实施例1中得到的染料溶液在pH值为10的条件下用400份10%的氢氧化钠处理,得到用下式表示的它的乙烯基磺酸形式的染料。
用盐酸将该溶液中和并喷雾干燥该溶液后,得到约2100份可将纤维素纤维染为深海军蓝色的含有蓝黑色盐的粉末。耐褪色性和被洗掉的能力与在实施例1中得到的染色物一致。
应用实施例A
将0.3份实施例1的染料溶解在100份的软化水中并加入3克芒硝(煅烧过的)。将染色浴加热到50℃,然后加入10份棉织物(漂白过的)。在50℃的条件下30分钟后,将0.4份碳酸钠(煅烧过的)加入到浴中。在加入碳酸钠的过程中温度保持在50℃。接着将染色浴加热到60℃,并且在60℃进一步染色1小时。
然后用流动的冷水漂洗染色织物3分钟,然后用流动的热水再漂洗3分钟。在500份含有0.25份马赛皂的软化水中,在煮沸的条件下洗涤染色物15分钟。用流动的热水漂洗(3分钟)和离心后,在约70℃的干燥橱中将染色物干燥。得到的海军蓝棉染色物表现出良好的耐褪色性,特别高的耐湿性,以及对于氧化的影响的稳定性。
应用实施例B
在含有100份软化水和3克芒硝(煅烧过的)的染色浴中加入10份棉织物(漂白过的)。在10分钟之内将浴加热到50℃,并且加入0.5份实施例1的染料。在50℃的条件下30分钟后,加入1份碳酸钠(煅烧过的)。然后将染色浴加热到60℃并在60℃继续染色45分钟。
按照应用实施例A的方法,用流动的冷水漂洗染色织物,然后用热水漂洗,并在煮沸的条件下洗涤。漂洗和干燥后,得到海军蓝棉染色物,它具有与应用实施例A中同样好的耐褪色性。
同样地,按照应用实施例A或B中描述的方法,将实施例2-8的染料或所列举染料的混合物用于染棉。由此得到的棉染色物是海军蓝色并表现出良好的耐褪色性。
应用实施例C
按照常规的印刷方法,将一种包括下列成分的印刷浆料施用于棉织物。
40份实施例1的染料
100份尿素
350份水
500份4%藻酸钠增稠剂和
10份碳酸氢钠
总共1000份
将印刷过的织物干燥并固定在102℃-104℃的蒸汽中4-8分钟。在冷水中洗涤和然后在热水中漂洗,在煮沸的条件下(按照应用实施例A中描述的方法)洗涤,并干燥。通常得到具有良好的耐褪色性的海军蓝印刷品。
同样地,按照应用实施例C中给出的方法,将实施例2-8的染料或所列举染料的混合物用于印刷棉织物。得到的所有印刷品均是海军蓝色,并表现出良好的耐褪色性。
应用实施例D
