<p>KU21737 TEMPERATURE INDICATING DEVICE USING A PRESSURE-SENSITIVE ADHESIVE SEAL There is provided a temperature indicating device such as a thermometer having a thermally conductive foil as a carrier layer, the carrier layer having one or more cavities formed by depression in the foil material. The depressions are filled with solid mixtures which melt at predetermined temperatures and are composed of ortho-chloronitrobenzene, ortho-bromonitrobenzene, and a dyestuff. A transparent cover layer seals the cavities and their contents. The transparent cover layer and carrier layer are bonded to each other by means of a pressure-sensitive adhesive which includes polyisobutylene.</p> |
