Abstract (en)
[origin: WO2009127529A1] The present invention relates to a time temperature indicator comprising a spiropyran in a colored state and a modifier which is able to control the coloration and decoloration kinetics. The modifier which must be able to form with the spiropyran mixed solids with an amorphous, crystalline or mixed amorphous-crystalline structure.
