Abstract

La présente invention concerne une feuille lumineuse constituée a) d'un film de plastique sélectionné dans le groupe formé par le polyéthylène, le polypropylène, les polyesters et les polyamides, et b) d'une peinture contenant de la poudre phosphorescente qui est appliquée sur un côté de ladite feuille. Pour obtenir une feuille lumineuse utilisable présentant une phosphorescence qui est plusieurs fois supérieure à celle d'une feuille lumineuse classique, on utilise un phosphore lumineux constitué d'un aluminate de métal alcalino-terreux avec Eu en tant qu'activateur principal; ledit phosphore lumineux ayant un diamètre particulaire compris entre 20 et 100 νm; et la poudre phosphorescente.
