The invention concerns a multilayer body and a process for producing a multilayer body. The multilayer body has a transparent first layer in which a multiplicity of cylindrical lenses of a length of more than 2 mm and a width of less than 400 mum are shaped, which are arranged in accordance with a microlens grid spanning a first co-ordinate system having a co-ordinate axis X1 which is determined by the focal point lines of the cylindrical lenses, and a co-ordinate axis Y2 perpendicular thereto. |
