An article represented by a container that is formed of a thermoplastic resin blended with a metal or a metal compound that can react with a corrosive gas or a volatile sulfur compound and give a color. The thermoplastic resin includes at least one metal selected from three metals of Zn, Sn and Mn or one metal compound thereof, and a metal or a metal compound that is not any of these three metals and that can react with the corrosive gas or the volatile sulfur compound and give a color. The metal selected from the three metals or the metal compound functions as a scavenger for the corrosive gas or the volatile sulfur compound.

Protective films, uses thereof, and ways of making such films are provided, where the protective films provide improved stain resistance in protecting a painted surface. Such protective films can include a first layer and a second layer. The first layer can include a polyurethane acrylate and a silicone modified additive, where the first layer has a first face and a second face, and the first face has a first coating including silicone. The second layer can include a thermoplastic polyurethane that can be based on polycaprolactone, where the second layer has a first face and a second face, the first face of the second layer contacts the second face of the first layer, and the second face has a second coating that includes a pressure sensitive adhesive.

The invention relates to devices for indicating the history of products, e.g., with regard to the temperature progression. The device according to the invention comprises a covering layer, an indicator layer, an activator layer, and an optional delaying layer. By means of heating, moisture is released, which, in the case of some embodiments, migrates first into the delaying layer and then into the activator layer. There, an activator is mobilized and migrates together with the moisture into the indicator layer. By interaction of the indicator with the activator in the presence of moisture, a color conversion occurs, which indicates the exceedance of the critical temperature. The invention further relates to methods for producing the device according to the invention and to applications of the device according to the invention, e.g., in the temperature monitoring of sensitive products.
