Zusammenfassung:The method involves utilizing liquid crystals in microcapsules having size 6 and 12 micrometer, isolated, filterable and redispersed in an aquatic medium. The microcapsules are obtained by introducing an anti-agglomerating agent before the formation of a capsular wall. The microcapsules have a mixture of liquid crystals with three phase transitions with respect to the temperature. L'invention concerne un procédé de préparation d'étiquettes indiquant la température idéale de consommation du contenu d'un emballage, à l'aide de cristaux liquides, caractérisé en ce que le procédé amélioré utilise les cristaux liquides dans des microcapsules de taille comprise entre 6 et 12mum, isolées, filtrables et redispersables dans un milieu aqueux.
