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.
