外文摘要：The use of synthetic dyes to colour leather has a long tradition。 Typically anionic acid dyes are used and this category consists of a number of chromophores which provide us with a wide range of colours and performance properties。 For the tanner the chemistry and evaluation of dyes is often like a black box。 But problems can arise when what appears to be commercially the same dye is found to perform differently on the leather。 These variations are not well understood。 With the introduction of the REACH Regulation in Europe there will be a need for the dye manufacturers to look more closely at the composition and structures of the dye molecules。 Traditional methods of analysing dyes will be challenged and new techniques will be required。 While HPLC now has come into routine use for dye analysis， one interesting relatively new development is the use of HPLC - MS。 This can prove to be a very useful tool for determining the structural components present in a dye。 The advantages and limitations of the analytical techniques used for typical leather dyes will be presented and explained。
