Abstract

La présente addition concerne des perfectionnements aux produits photoluminescents dans leur masse tels que décrits et revendiqués dans le brevet principal. Les produits photoluminescents comprennent des substances <<amont>> puisant de l'énergie dans les faibles longueurs d'ondes et la réémettant au niveau du spectre d'absorption d'une substance phosphorescente, et des substances << aval >> du type fluorescent. Préférentiellement la substance << amont >> est le diphényloxazol. Application aux produits de sécurité.
