Mordant dyes are those dyes which require a mordant in their application and which upon combination with the mordant deposit insoluble color on the substrate, eg, dyes with metal chelating groups.酸性媒介染料，是那些染料需要媒在其应用，并结合后，与媒存款不溶性的色彩衬底，例如，染料与金属螯合组。 Like the name suggests these dyes require a mordant.像，顾名思义，这些染料需要一个媒介。 Mordants are substances of organic or inorganic origin which combine with the coloring matter and are used to fix the same in the production of the color.媒染剂是物质的有机或无机的原产地结合起来，与色彩的事，并用来修复，同时在生产中的颜色。 For the purpose of this class, such materials as oils and sulfonated oils, soaps, fats and higher acids, are not generally considered as mordants, but as coming within the scope of “assistants” in dyeing.为目的的这一类，这类材料作为油脂和磺化油，肥皂，油脂和较高的酸，一般不被视为媒染剂，但作为未来的内部范围“助理”在染色。 The mordant substances include such acids as tannic acid, sumac, gall nuts, bark extracts, oleic and stearic acids, and Turkey red oil; and metallic substances such as various combinations or soluble salts of chromium, aluminum, iron, copper, and tin.该媒介物质，包括酸单宁酸， sumac ，胆，坚果，树皮提取物，油酸和硬脂酸酸，红色和土耳其的石油和金属物质，例如各种组合或可溶盐的铬，铝，铁，铜，锡。 The latter, the metallic mordants, are more used than the acid mordants.就后者而言，金属媒染剂，更用较酸的媒染剂。 Mordant improves the fastness of the dye on the fibre such as water, light and perspiration fastness.媒，提高牢度的染料对纤维，例如水，光，汗牢度。 The choice of mordant is very important as different mordants can change the final colour significantly.选择媒介是非常重要，因为不同的媒染剂可以改变最后的颜色显着。 Most natural dyes are mordant dyes and there is therefore a large literature base describing dyeing techniques.大多数天然染料是酸性媒介染料和因此，有大型文学基地描述染色技术。

Dyes are generally defined along the lines of being coloured, aromatic compounds that can ionise.染料一般的定义大致相同的颜色正，芳香族化合物，可以ionise 。 Although this definition infers that ionic interaction with oppositely charged tissue constituents is the norm, there are exceptions.虽然这个定义推导认为，离子的互动与相反被控组织的选民是规范，也有例外。 Some dyes require the presence of a metal to properly develop their colour or staining selectivity.一些染料，要求在场的金属妥善发展他们的肤色或染色的选择性。 These are termed mordant dyes.这些被称为媒介染料。 The Colour Index uses this as a classification and naming system.颜色指数使用此作为分类和命名系统。 Each dye is named according to the pattern: mordant + base colour + number每个染料命名为根据的模式：媒+基地+电话号码的颜色

These dyes are thereby specifically identified as dyes of the stated colour, and whose primary staining mechanism requires the presence of metal atoms.这些染料，从而具体确定为染料所阐明的肤色，和其主要染色的机制，要求在场的金属原子。 Note that this is a functional and colour classification.请注意，这是一个功能和颜色分类。 It contains no chemical information neither does it imply that dyes with similar names but unique numbers are in any way related.它不包含的化学信息，也没有暗示，染料与类似的名称，但独特的号码以任何方式有关。 It should also be noted that the classification refers to the primary mechanism of staining.还应当指出，分类是指主要机制的染色。 Other mechanisms may also be possible.其他机制也可能是不可能的。

The most commonly used mordant dyes have hydroxyl and carboxyl groups and are negatively charged, ie anionic.最常用的媒介染料有羟基和羧基团体和是负电荷，即阴离子。 It is convenient to view these as a specialised subgroup of acid dyes.这是方便，以查看这些作为一个专门小组的酸性染料。 Some other mordant dyes may possess amino groups, and are cationic overall.其他一些媒介染料可能具有氨基酸团体，是阳离子的整体。 Despite this, they must still have hydroxyl or carboxyl groups, since lake formation requires it.虽然如此，他们仍必须有羟基或羧基的团体，自湖的形成，需要它。 Mordant dyes can usually stain by ionic interaction in the same way as other ionisable dyes.媒介染料染色，通常可以由离子相互作用，在同样的方式作为其他ionisable染料。 The colour is often pale, sometimes so pale that the results have no value.颜色往往是苍白，有时苍白，所以说，结果没有任何价值。

It is often noted that when a mordant dye forms a lake with a metal, there is a strong colour change.它往往是指出，当一个媒介染料，形成了一个湖，与金属，有一种强烈的颜色变化。 This is because metals have low energy atoms.这是因为金属有低能量的原子。 The incorporation of these low energy atoms into the delocalised electron system of the dye causes a bathochromic shift in the absorption.把这些低能量的原子进入delocalised电子系统的染料造成红移在吸收。 It is this delocalised electron system which is fundamentally responsible for colour in dyes.这是delocalised电子系统，是从根本上负责的颜色在染料。 Since different metal atoms have differing energy levels, the colour of the lakes may also differ.由于不同的金属原子有不同的能量水平，颜色的湖泊也可能有所不同。

The most commonly used mordant dye is undoubtedly hematein (natural black 1), whose status as a natural product supercedes its mode of dyeing, apparently.最常用的酸性媒介染料，无疑是hematein （天然色黑色1 ） ，其地位，作为一个天然产物取代其模式印染，显然。 Others are eriochrome cyanine R (mordant blue 3) and celestine blue B (mordant blue 14), both used as substitutes for alum hematoxylin but with a ferric salt as the mordant.其他铬菁R （下媒蓝3 ）和天青石蓝B （媒介蓝14 ） ，两者都用来作为替代明矾苏木，但与铁盐作为媒介。 Alizarin red S (mordant red 3) is valuable for the demonstration of calcium, particularly in embryo skeletons.茜素红S （媒介红3 ）是有价值的为示范，钙，尤其是在胚胎骨骼。
