The reactive group, of which there may be more than one, may be chloro, nitro, sulphonate, phosphate, borate, citrate, thiocyanate, sulphate, amino or carboxyl. Mixtures of different organic compounds may be used, and suitable ones are alkali metal, ammonium or organic base salts of long chain aliphatic carboxylic acids, e.g. oleic, palmitic and stearic acids; half esters of long chain dicarboxylic acids; salts of sulphonated or sulphated long chain mono-carboxylic acids, e.g. ammonium, sodium and potassium salts of sulphonated or sulphated oleic and palmitic acids; sulphonated or sulphated triglycerides, e.g. medium sulphated cod oil and lightly sulphated cold test neatsfoot oil; and long chain aliphatic amino acids. The treatment with the organic compound may be carried out in the presence of a water soluble or water miscible alcohol or liquid hydrocarbon. The salt for  the third stage may be a basic salt of chromium, aluminium, zirconium or cerium &c, or a normal salt e.g. a copper, zinc, zirconium, aluminium or nickel sulphate. The salt may be "masked" with a formate, acetate phthalate, citrate &c. Dyeing may be performed before or after the third stage. Softer leathers are obtained by using a small amount of hydrocarbon solvent or a straight oil, &c., neatsfoot or sperm oil, emulsified in the organic compound.
