MULTIPLE-DISPLAY TYPE ULTRASMALL TEMPERATURE SENSITIVE LABEL

PROBLEM TO BE SOLVED: To provide a multiple-display type ultrasmall temperature sensitive label that can display a plurality of setting temperature values, while being a markedly small size and allow a user to readily discriminate the same type of temperature sensitive labels from one another. SOLUTION: This multiple-display type ultra-small temperature sensitive label is so configured that an adhesive layer is formed on the rear face and a temperature-sensitive paint which changes irreversibly, from an opaque state to a transparent state at a desired temperature preset, beforehand and is formed by mixing and kneading particles of a petroleum wax, a viscous agent and a solvent, are applied to the surface of a rectangular substrate 3 that is colored with a black or a desired color. According to this constitution, the fact that temperature of the label exceeds the preset temperature can be displayed. A plurality of temperature display sections 4, constituted of any one of circular, triangular or blank square forms are formed on the surface at desired intervals. COPYRIGHT: (C)2009,JPO&INPIT
