Abstract

L'invention concerne une composition thermochromique réversible renfermant (1) un composant organique principal qui peut changer de couleur sous l'effet d'une énergie thermique et (2) un composant organique auxiliaire qui rend au premier composant sa capacité de changement de couleur à une température prédéterminée. Les deux composants sont incorporés à une matrice polymère. Les articles élaborés à partir de cette composition changent de couleur ou deviennent incolores à une température prédéterminée, et ils présentent une réponse précise à la température. Le procédé de fabrication de la composition est simple, peu onéreux et exécutable selon des moyens techniques classiques.
