Abstract

Disclosed are a gel which reversably changes its transparence to light as a function of the temperature, a method for its preparation and its utilization in construction elements such as multiple discs, double-plastic discs, simple discs or other transparent bodies. The gel contains a polyether compound with ethylen oxide groups, a wetting agent with ethylen oxide groups in the molecule, a water-miscible solvent, a carboxyvinyl polymer, a base, water and, optionally, other additives.
