Abstract: 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.

Abstract: The invention relates to a cast resin mixture for bonding substantially sheet-shaped elements, such as glass pane or the like, with a content of at least one non-functionalized acrylic and/or methacrylic ester and at least one functionalized alkyl ester of (meth)acrylic acid, optionally at least one plasticizer, optionally at least one cross-linking agent, optionally at least one primer and optionally at least one polymerization initiator. To improve this cast resin mixture in versatility of use and ease of handling, and to allow glass panes and the like to be bonded to one another reliably and durably, while optionally embedding function elements the acrylic and/or methacrylic ester(s) comprise(s) at least one constituent from the following group: all branched and unbranched saturated aliphatic (meth)acrylic esters, in particular methyl-, ethyl-, n-propyl-, iso-propyl-, n-butyl-, iso-butyl-, sec-butyl-, tert-butyl- and 2-ethyl-1-hexyl-(meth)acrylic esters.

Abstract: An electrochromic pane arrangement is disclosed having a first transparent electrode substrate or glass pane and a second electrode substrate or glass pane arranged parallel to and at a distance from the first glass pane. An ion conducting layer is disposed adjoining the two electrode substrates and consists of a polymer matrix containing at least one salt including difficult to oxidize anions. The conducting layer also includes one dopant suitable for the provision of cations, preferably metal ions. A surface of the first electrode substrate faces toward the ion conducting layer and is a first transparent electrode layer. Adjacent to it is an actively electrochromic layer in surface contact with the ion conducting layer, preferably of tungsten trioxide. This ion conducting layer has a reversibly variable transparency and/or color as a result of absorption or emission of electrons via the first electrode layer and acceptance or emission of ions of the dopant from or to the ion conducting layer.
