摘要

One-part, multiphase color developer concentrate has an aqueous phase and an organic phase of partly water-miscible solvent(s) and contains N,N-disubstituted hydroxyl-amine or -amide, N-alkyl-hydroxyl-amine or -amide or hydroxylamine compound as antioxidant. One-part, multiphase color developer concentrate has an aqueous phase and an organic phase of partly water-miscible solvent(s) and contains N,N-disubstituted hydroxyl-amine or -amide of formula (I), N-alkyl-hydroxyl-amine or -amide of formula (II) or hydroxylamine compound of formula (III) as antioxidant: R1 = (substituted) alkyl; R2 = (substituted) alkyl or aryl group; n = 0 or 1; R3 = (substituted) alkyl or acyl group; R4 = (substituted) alkylene, optionally with oxygen (O) atoms in the chain; m = at least 2; R1 and/or R2 contains hydroxyl (-OH), carboxyl (-COOH) and/or sulfo (-SO3H) group(s).
