摘要： The invention relates to monoazo dyes of general formula I and the salts thereof. Said monoazo dyes of general formula I are particularly suitable for dyeing leather and impart a yellow tint with excellent fastness to leather dyed with said dye. In formula I, n represents 0, 1, or 2; R
1 represents hydrogen, C
1 -C
4 alkyl, COOH, C
1 -C
4 alkoxycarbonyl, C
1 -C
4 alkoxy, CN, or halogen; R
2 represents a -CH=CH
2 group or CH
2 -CH
2 -Q group in which Q represents a group that can be separated in alkaline conditions; naphth represents a group of formula X or Y, in which m represents 0, 1, or 2, and * means the link to the nitrogen of the pyrazole ring.

摘要： The invention relates to a method for the colouring of leather with at least one dye (F), comprising at least one group of formula (A) which may be activated under alkaline conditions, where ---- represents the bond to the remainder of the dye molecule, X is an electron-withdrawing group, k = 1, 2, or 3, n = 0 or 1 and B is a CH=CH2, or CH2-CH2-Q group, where Q is a group which may be cleaved under alkaline conditions, comprising the treatment of the leather with an aqueous liquor, containing at least one dye (F), at a pH value of at least 7.5. The invention further relates to novel dyes which are particularly suitable for the reactive colouring of leather.
