Abstract

La présente invention a pour objet d'obtenir de manière efficiente des propriétés satisfaisantes de diffusion de la lumière et des propriétés de haute résistance aux flammes. Une base (2) constituée d'un tissu de verre est revêtue de couches (3B, 3C) de résine pour configurer une feuille qui présente des propriétés de diffusion de la lumière et des propriétés de transmission de la lumière. Les couches (3B, 3C) de résine ont été configurées comme des couches de diffusion de la lumière et retardatrices de flamme en incorporant un agent inorganique particulaire de résistance aux flammes présentant des propriétés de diffusion de la lumière à la place d'un pigment blanc ou d'un agent de diffusion de la lumière dans une résine de base.
