Aniline leather
Aniline leather is the colloquial term for leather that is dyed exclusively with soluble dyes and which is not covered by a top or pigment coating ( finishing ).
properties
The transparent coloring preserves the natural surface with the so-called " grain pattern ", that is, the visibility of the hair holes and the entire leather structure. Therefore only the best skin ranges are suitable for pure aniline coloring. Even with nappa leather , the condition of many hides does not allow uncovered dressing due to too much grain damage.
Naming
The term “natural leather” has not caught on, although “aniline leather” has not been dyed with the toxic aniline dyes for a long time . Historically, the name originated from the first synthetic dyes that were made on the basis of aniline ( tar dyes or aniline dyes ) and thus found their distribution in leather production . In a broader sense, all artificially produced organic dyes were referred to as aniline dyes.
Legal position on coloring
In Germany, the dyes used today are subject to the provisions of the Consumer Goods Ordinance or the ban on the use of certain azo dyes if they offer indications of a health hazard.
