Abstract
(EN)
Tanned leather, skin or pelt is produced by non-metal tanning, comprising the step of tanning a bated hide, skin or pelt with a tanning agent (A), the tanning agent (A) being at least one compound of formula (I), wherein Hal signifies chlorine or fluorine, X signifies N or CR, Y signifies hydrogen, C1-8-alkyl, C1-4-alkyl-carbonyl, C1-4-alkyl-sulphonyl or a radical of formula (la), or (lb) R signifies hydrogen or chlorine, q is 1 to 10 and M signifies hydrogen or an alkali metal cation or an ammonium cation, the ammonium cation being a protonated tertiary amine or a quaternary ammonium cation, in a tanning bath, the tanning bath having a pH of from 6 to 10 at the beginning of the tanning step.

(FR)
Selon la présente invention, un cuir, une peau ou une fourrure sont produits par tannage non métallique, comprenant l'étape de tannage d'un cuir, d'une peau ou d'une fourrure bruts avec un agent de tannage (A), l'agent de tannage (A) étant au moins un composé de formule (I), dans laquelle Hal désigne un chlore ou un fluor, X désigne N ou CR, Y désigne un hydrogène, un alkyle en C1-8, un (alkyle en C1-4)-carbonyle, un (alkyle en C1-4)-sulfonyle ou un radical de formule (Ia) ou (Ib), R désigne un hydrogène ou un chlore, q vaut de 1 à 10 et M désigne un hydrogène ou un cation de métal alcalin ou un cation ammonium, le cation ammonium étant une amine tertiaire protonée ou un cation ammonium quaternaire, dans un bain de tannage, le bain de tannage ayant un pH de 6 à 10 au début de l'étape de tannage.
