摘要
Substituted hydroxylamine antioxidants can be prepared by reacting hydroxylamine or a mono-substituted hydroxylamine with an epoxide. The antioxidant reaction product is not removed from the reaction mixture, but is used without separation after combination with a color developer to provide a photographic color developer composition. The antioxidants are highly water soluble and thus exhibit no objectionable odor.
