    Abstract: Tanned leather is (a) pretreated in an aqueous and alkaline medium either with ammonia, primary amines or a mixture of ammonia and primary amines and then with a polyfunctional organic compound containing at least one aldehyde group as a functional group, or (b) in an aqueous and acidic medium with a polyfunctional organic compound and then ammonia, primary amines or a mixture of ammonia and primary amines, and (c) then dyed in an aqueous and alkaline medium with a water-soluble dye containing at least one functional group which is capable of reacting with one of the functional groups of the organic compound, forming a covalent bond. A tanned and dyed leather is obtainable with a high color intensity, outstanding wet fastness and excellent grain tightness, wherein the dye is permanently and covalently bonded to the leather via a bridging group, preferably in the region of the surface, and the bridging group is essentially bonded to the leather via —N═CH— groups.

    Abstract translation: 鞣革是（a）在水性和碱性介质中用氨，伯胺或氨和伯胺的混合物预处理，然后与含有至少一个醛基作为官能团的多官能有机化合物预处理，或（b）在 具有多官能有机化合物，然后是氨，伯胺或氨和伯胺的混合物的水性和酸性介质，和（c）然后在水性和碱性介质中用含有至少一个官能团的水溶性染料染色， 能够与有机化合物的官能团之一反应，形成共价键。 可以获得具有高颜色强度，优异的耐湿牢度和优异的颗粒紧密性的鞣制和染色的皮革，其中染料通过桥连基团优选在表面区域永久地共价结合到皮革上，并且桥接基团是 基本上通过-N-CH-键合到皮革上。
