Homogeneous liquid complexes of anionic organic dyes and quaternary ammounium and dyeing method

本发明涉及阴离子有机染料与季铵化合物的液体配合物，其是均匀的并且基本上不含有不想要的盐。特别优选的季铵化合物为那些包含烷氧基化部分的化合物。这种配合物是通过两种化合物间的离子键形成的。由染料的阳离子和季铵化合物的抗衡离子形成的不想要的盐可基本上从配合物中除去，从而获得一种均匀的液体染色剂，其易于分散在不同的介质中，并具有极其优异的迁移性能和着色性能。本发明也涉及制备上述无盐的阴离子染料/季铵化合物配合物的方法，采用这种配合物用来对热塑性塑料、热固性塑料组合物进行染色的方法，以及将这种配合物与含水和无水制剂和油墨组合物掺混的方法。 This invention relates to liquid complexes of anionic organic dyes with quaternary ammonium compounds which are homogeneous and thus substantially free of unwanted inorganic salts. Of particular interest as quaternary ammonium compounds are those which comprise alkoxylated moieties. Such complexes are formed through ionic bonds formed between the two compounds. The complexes are then removed of substantially all resultant unwanted salt formed from the cations of the dye and the counter ions of the quat so as to obtain an homogeneous liquid colorant which easily disperses within different media and which possess favorable migration and coloring characteristics. This invention also concerns methods of making the aforementioned salt-free anionic dye/quat complexes as well as methods of utilizing such complexes for dyeing thermoplastic and thermoset compositions and the incorporation of such complexes within aqueous and non-aqueous formulations and ink compositions.
