Multilayer body with microlens arrangement

摘要

A multilayer body for viewing a front face and rear face with light passing through is described, with the multilayer body (1) comprising one or more transparent first layers (10) and a second layer (14) with a micropattern of opaque first subareas and transparent second subareas. One of the first layers (10) has a surface profile on its surface facing away from the second layer (14), which surface profile forms an arrangement of a multiplicity of first microlenses (12). The thickness of this first layer (1) or of this first layer (1) and one or more further first layers (1) arranged between this first layer (1) and the second layer (14) corresponds approximately to the focal length of the first microlenses.
