发明名称 Multilayer body
摘要 The invention relates to a multilayer body (2) having a transparent first layer (13). In a first region (31) of the transparent first layer (13) a plurality of microlenses (21) are moulded, which are arranged in accordance with a microlens grid. Furthermore, the multilayer body (2) has a second layer (12) arranged beneath the first layer (13) and in a fixed position with respect to the first layer (13), the second layer having a plurality of microimages (22) which, in order to generate first optically variable information, are arranged in accordance with a microimage grid and in each case overlapping at least in areas with one of the microlenses (21) of the microlens grid. The grid widths (41, 42) of the microimage grid and the microlens grid are each less than 300 μm in at least one direction in space.
