Abstract

Este elemento (1) estratificado transparente comprende: - dos capas externas transparentes que tienen sustancialmente el mismo índice de refracción y cada una tiene una superficie (2A, 4A) principal externa uniforme, y - una capa central intermedia entre las capas externas, la capa central que incluye al menos una capa transparente de índice de refracción diferente del de las capas externas o una capa de metal. Todas las superficies de contacto entre dos capas adyacentes del elemento (1) estratificado, de las cuales una de las dos capas es una capa de metal, o que son dos capas transparentes de diferentes índices de refracción, que se texturizan y son paralelos entre sí, la reflexión de luz difusa del elemento (1) estratificado en el lado de al menos una de las capas externas que tiene al menos un máximo en una dirección diferente de la dirección de reflexión especular. Además, la superficie del elemento (1) estratificado se divide en una pluralidad de pixeles del mismo tamaño, cada pixel que tiene al menos un lado de longitud más pequeña que o igual a 500 µm, la textura de cada superficie de contacto texturizada dentro de cada pixel que tiene una distribución fpix(?x, ?y) de pendiente que tiene un coeficiente de correlación ?? con la distribución ftot(?x, ?y) de pendiente de la textura de la superficie de contacto texturizada total, siendo de este modo el elemento estratificado, para un ejemplo de N pixeles, el promedio de los coeficientes de correlación ?? (fpix, ftot) de cada pixel de la muestra es mayor que o igual a 0.8.
