ABSTRACT:
Acyldihydroxybenzene azo compounds of the formula ##STR1## are provided where A represents a benzene radical which is unsubstituted or mono, di, or trisubstituted or a naphthalene radical which is unsubstituted or mono or disubstituted with any of alkyl of 1-4 carbon atoms, alkoxy of 1-4 carbon atoms, trifluoromethyl, cyano, nitro or halogen and R is alkyl of 1-4 carbon atoms, benzyl or phenyl. The compounds when applied to metallized polyolefin fabrics, particularly nickel-containing polypropylene fabrics, produce dyeings of strong bright shades which are exceptionally fast to light, dry cleaning, crocking, gas and heat.
