The invention relates to a multi-layered plastic strip or plate having a three- dimensional optical aspect. The invention also relates to a method for the production of the multi-layered plastic strip or plate which enables a distinctive and if desired a high-definition three-dimensional optical aspect to be obtained in a simple manner. According to said method, a base layer is produced which is stamped on one surface, having a transparent cover layer and optionally another layer which are connected together in a non-positive fit in such a way that the structure of the surface stamped by the base layer is transferred almost authentically onto or into the transparent cover layer.
L'invention concerne une bande ou une plaque en matière plastique multicouche à aspect en relief, ainsi qu'un procédé de production de cette bande ou plaque permettant d'obtenir facilement un aspect en relief prononcé et présentant si nécessaire une grande netteté de contours. Le procédé selon l'invention consiste à assembler une couche de base, estampée sur une seule face, avec une couche de revêtement transparente, et éventuellement une autre couche, par liaison de force de telle sorte que la structure de la face estampée de la couche de base soit transposée sensiblement à l'identique sur ou dans la couche de revêtement transparente.
