Claim:
An article of manufacture comprising (a) a cotton dyed fabric and, deposited thereon, (b) from 0.05% by weight to 1% by weight, based on the weight of the cotton fabric, of at least one compound selected from dialkylhydroxylamine stabilizer salts, said dialkylhydroxylamine stabilizer salts are of the formula (R 1 R 2 N—OH)·(HY) where R 1 is alkyl of 1 to 36 carbon atoms, cycloalkyl of 5 to 12 carbon atoms or aralkyl of 7 to 9 carbon atoms; or R 1 is said alkyl, cycloalkyl or aralkyl substituted by one to six alkyl of 1 to 12 carbon atoms, halogen, cyano, E 1 O—, E 1 CO—, E 1 OCO—, E 1 COO—, E 1 S—, E 1 SO—, E 1 SO 2 —, —NH 2 , —NHE 1 , —NE 1 E 2 , —PO(OE 1 )(OE 2 ) or —OPO(OE 1 )(OE 2 ) groups; R 2 independently has the same meaning as R 1 , where at least one of R 1 and R 2 contains a hydrogen alpha to the —NOH moiety; or R 1 and R 2 together form a C 2-12 heterocyclic ring which contains at least one carbon substituted hydrogen alpha to the —NOH moiety, where said C 2-12 heterocyclic ring is unsubstituted or is substituted by one to three alkyl of 1 to 12 carbon atoms, halogen, cyano, E 1 O—, E 1 CO—, E 1 OCO—, E 1 COO—, E 1 S—, E 1 SO—, E 1 SO 2 —, —NH 2 , —NHE 1 , —NE 1 E 2 , —PO(OE 1 )(OE 2 ) or —OPO(OE 1 )(OE 2 ) groups; or where said C 2-12 heterocyclic ring is interrupted by one to three —O—, —NE 1 -, —CO—, —CONE 1 -, —S—, —SO—, —SO 2 —, —COO—, —PO 3 — or —PO 4 E 1 groups; or where said heterocyclic ring is both substituted and interrupted by said groups; E 1 and E 2 independently are hydrogen, alkyl of 1 to 4 carbon atoms or alkyl of 1 to 4 carbon atoms substituted by one to three hydroxyl groups; or E 1 and E 2 independently are an oligomer of poly(ethylene glycol) or poly(propylene glycol) terminated by hydroxyl, methoxy, acetate or propionate, where the oligomer has a molecular weight up to about 500; and HY is an inorganic or organic acid, wherein Y is phosphate, phosphonate, carbonate, bicarbonate, nitrate, chloride, bromide, bisulfite, sulfite, bisulfate, sulfate, borate, formate, acetate, benzoate, citrate, oxalate, tartrate, acrylate, polyacrylate, fumarate, maleate, itaconate, glycolate, gluconate, malate, mandelate, tiglate, ascorbate, polymethacrylate, a carboxylate of nitrilotriacetic acid (NTA), a carboxylate of diethylenetriaminepentamethylenephosphonic acid (DTPMPA), a carboxylate of hydroxyethylethylenediaminetriacetic acid (HEDTA), a carboxylate of ethylenediaminetetraacetic acid (EDTA), a carboxylate of diethylenetriaminepentaacetic acid (DTPA), a carboxylate of diethylenediaminetetraacetic acid a carboxylate of diethylenetriaminepentaacetic acid, an alkylsulfonate or an arylsulfonate.
