摘要： Azo dyes of the formula:

WHEREIN X represents the bivalent grouping -CH2-NH-CH2-, m represents an integer of 2 to 4, and Y represents a radical of the benzene, naphthalene, heterocyclic or azo series, at least one of which is substituted by at least one sulphonic or carboxylic acid group, and salts thereof with an amine or ammonium compound, and nitrosated, oxidised and metalliferous derivatives thereof; the dyes, derivatives and salts are useful for the color-finishing of leathers, for example for the aniline finishing of skins, whether or not previously dyed, and for the finishing of leathers with a buffed or artificial hair side, as well as for the spray-gun dyeing of full-grain leathers on which they give very vivid transparent shades which are very fast, especially to light and wet rubbing.
