Abstract: NON-IONIC, HEAVY METAL (NI''II) AMINE ARYLAZOARYL COMPOUNDS OF THE FORMULA:

R-NH2 NI
WHEREIN R IS AN N-ALKYL OF FROM 4 TO 18 CARBON ATOMS, A AND B ARE EACH ARYL AND X AND Y, INDIVIDUALLY, ARE H, OH, CI, BR, NO2, CN, SO2-ALKYL OF FROM 1 TO ABOUT 4 CARBONS OR ALKOXY OF FROM 1 TO ABOUT 4 CARBONS, USEFUL IN DYEING EITHER NYLON OR POLYPROPYLENE FIBERS, ARE PROVIDED AS WELL AS A METHOD FOR DYEING THEREWITH. A PREFERRED COMPOUND FOR DYEING NYLON IS THE NICKEL-N-BUTYLAMINE COMPLEX OF 1-(2-HYDROXYPHENYLAZO)-2-NAPHTHOL. A PREFERRED COMPOUND FOR DYEING POLYPROPYLENE IS THE NICKEL-N-DECYLAMINE COMPLEX OF 1-(5-CHLORO-2-HYDROXYPHENYLAZO)-2-NAPHTHOL. THE DYEINGS PROVIDED BY THE COMPOUNDS ON NYLON AND POLYPROPYLENE ARE OF HIGH TINCTORIAL STRENGTH, GOOD LIGHT-FASTNESS AND UNIFORM SHADE.
