Title (EN) TEMPERATURE-SENSITIVE INDICATOR
(FR) INDICATEUR SENSIBLE À LA TEMPÉRATURE
Abstract:
(EN) A temperature-indicator product comprising a visual indicator comprising a thermochromic colour-memory composition and comprising an electron-donating colouring organic compound (A), an electron-accepting colouring organic compound (B) and reaction medium compound (C). The visual indicator comprises a first portion comprising a first thermochromic colour-change composition in its lower temperature state and a second portion comprising a second thermochromic colour-change composition in its higher temperature state. The product is useful as a tamper-evident indicator or as a freeze indicator.
(FR) La présente invention concerne un produit indicateur de température comprenant un indicateur visuel comprenant une composition de mémoire de couleur thermochrome et comprenant un composé organique colorant donneur d'électrons (A), un composé organique colorant accepteur d'électrons (B) et un composé de milieu de réaction (C). L'indicateur visuel comprend une première partie comprenant une première composition de changement de couleur thermochromique dans son état de température inférieur et une seconde partie comprenant une seconde composition de changement de couleur thermochromique dans son état de température supérieur. Le produit est utile en tant qu'un indicateur d'inviolabilité ou en tant qu'indicateur de congélation.
