Abstract: front page image
(EN)The invention relates to multi-layer composites for use as a screen, having at least three layers, with an inner diffusing layer and at least one substrate layer on either side. The diffusing layer contains small particles having a narrow particle size distribution that are refractive-index mismatched with the polymer matrix. The multi-layer acrylic composition is useful as a projection screen.
(FR)L'invention concerne des composites multicouches utilisables en tant qu'écran, comportant au moins trois couches, dont une couche de diffusion interne et au moins une couche servant de substrat de chaque côté. La couche de diffusion contient de petites particules présentant une distribution de la taille des particules étroite et dont l'indice de réfraction ne correspond pas à celui de la matrice polymère. La composition acrylique multicouches est utilisable en tant qu'écran de projection.
