A multilayer body includes a transparent first layer. In the transparent first layer, a multiplicity of microlenses arranged in accordance with a microlens grid are impressed in a first region. Furthermore, the multilayer body includes a second layer, which is arranged below the first layer and in a fixed position with respect to the first layer and has a multiplicity of microimages arranged in accordance with a microimage grid and in each case in an at least regional overlap with one of the microlenses of the microlens grid for the purpose of generating a first optically variable information item. The grid pitches of the microimage grid and of the microlens grid in each case in at least one spatial direction are less than 300 &#x3bc;m.

A method for producing a security element formed as a lenticular flip, including a micro-optical layer, a carrier substrate and an image layer, wherein the image layer includes n images for n=1 to i which are visible from an n-th observation angle allocated to the n-th image, and wherein n is at least 1. The images are imaged on a photoresist with parallel light in contact print or by means of projection. After the photoresist is developed, an image layer which includes the i images is present.
