Abstract
Temperature indicating compositions are provided for use in disposable thermometers comprising a heat-conductive carrier sheet having at least one but preferably a plurality of regions (cavities) thereon, each region containing a thermally responsive substance which undergoes a change in state at a precise and predetermined temperature different from any other region. The thermally responsive materials used herein as temperature indicating compositions are solid solutions comprised of two components which, inter alia, have linear temperature-composition liquidous curves. The change of state of the solid solution in each region is readily detectable visually by an indicator system which is intimately associated with the solid solution in said regions in order to permit rapid and accurate visual determination of the temperature of the test subject.
