Abstract (en)
[origin: DE102005055634A1] Oxygen-scavenger/-indicator comprises at least one oxygen sorbent of a metal or a metallic component, which is convertible into oxygen by higher oxidation step; at least one complex former and/or redox indicator for metal or metal component in oxidized form; and at least one electrolyte, where at least one physical characteristic of the oxygen sorbent is changed by the complex former and/or interaction with the redox indicator. An independent claim is included for a composite system containing at least one carrier layer and at least one oxygen-scavenger/indicator.
