Beschreibung
Zusammenfassung:	The invention relates to the use of antioxidants of different kinds and concentrations in electrochromic elements having an ion conducting component to suppress self-discharging. In comparison to electrochromic elements known from prior art, electrochromic elements according to the invention show a significantly smaller increase in transmissivity for a period of time after the electric current necessary to decrease transmissivity is switched off. The use of sterically hindered amines and/or 1,3,5-trisubstituted phenols has proven particularly effective for this purpose.
