    摘要: 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 X signifies fluorine or chlorine, and/or (
    + NR
    3 )
    0.1 , wherein R is a substituted C
    1 to C
    6 alkyl group or an unsubstituted Ci to C6 alkyl group, an unsubstituted C
    6 to C
    10 aryl group or a substituted C
    6 to C
    10 aryl group or a C
    5 to C
    6 heteroaryl group. R1 signifies hydrogen, C
    1.8 -alkyl or an alkyleneoxy radical of formula (la), - (- C
    2-3 alkylene - O -)
    q - H (la) R2 signifies hydrogen, hydroxy, C
    1-4 -alkyl or C
    1-4 -alkoxy, m signifies 1 or 2, n signifies 0 to 2, q is of from 1 to 10, 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 tanning step, wherein the bated hide or skin or pelt is subjected to tanning with (A) without previous pickling.
