Abstract: 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.

Abstract: In a process for producing a multilayer body, an HRI layer made of a material having a high refractive index is applied to at least part of the surface area of a substrate. At least one partial region of the HRI layer is then physically removed from the substrate again by treatment with an alkaline solution. Additionally specified is a multilayer body that can be obtained by such a process.
