Aniline leather

Aniline leather is the colloquial term for a solid-colored exclusively with soluble dyes leather that has no coverage by covering or coating pigment ( dressing ).

Properties

The transparent color is replaced by the natural surface with the so-called " grain image ", i.e., the visibility of the holes, and the total hair leather structure. The term " natural leather " has not prevailed, although " aniline leather " is long gone stained with aniline dyes toxic. Historically, the name came from the first synthetic colors, which have been prepared on the basis of aniline ( coal-tar dyes and aniline dyes ) and had thus found their dissemination in the production of leather. In a broader sense, all organic dyes artificially produced were identified by aniline dyes.

In Germany, the dyes used today are subject to the provisions of the Commodities Regulation, or the prohibition of the use of certain azo dyes if they provide evidence of a health hazard.
