    • Described is a process for the level dyeing of polyacrylonitrile materials of slow, normal and rapid absorptive capacity with an aqueous dye liquor, which process comprises using a liquor containing at least one migrating cationic dye as well as, if required, further additives; and adding to the liquor, before, during or after dyeing, at least one organic cationic migration auxiliary.This process renders possible by the use of organic migration auxiliaries the obtainment of level single-shade and, in particular, combination-shade dyeings at normal dyeing temperatures.Particularly suitable migrating cationic dyestuffs are those having a more or less delocalized positive charge, the cation weight of which dyestuffs is smaller than 310, the parachor smaller than 750 and the log P (relative lipophil property) smaller than 3.6.Particularly suitable organic migration auxiliaries are those of which the cation weight is smaller than 250, the parachor smaller than 700 and the log P smaller than 6.4.
    • 描述了一种使用含水染料液进行慢,正常和快速吸收能力的聚丙烯腈材料的水平染色的方法,该方法包括使用含有至少一种迁移阳离子染料的液体,以及如果需要的话,还可添加其它添加剂; 并在染色之前,期间或之后向酒中加入至少一种有机阳离子迁移助剂。 该方法可以通过使用有机迁移助剂获得水平单色,特别是在正常染色温度下的组合色调染色。 特别合适的迁移性阳离子染料是具有或多或少的离域正电荷,其中染料的阳离子重量小于310,脱酰胺小于750,对数P(相对亲脂性)小于3.6的那些。 特别合适的有机迁移助剂是阳离子重量小于250,助溶剂小于700,对数P小于6.4的有机迁移助剂。
