Method for producing security elements having a lenticular flip

Described is a method for producing a security element (1) in the form of a lenticular flip, comprising a micro-optical layer (11), a carrier substrate (13) and an image layer (14), the image layer (14) comprising n images (14l, 14r) for n = 1 to i which are visible from an n-th observation angle as...

More Information
Summary:Described is a method for producing a security element (1) in the form of a lenticular flip, comprising a micro-optical layer (11), a carrier substrate (13) and an image layer (14), the image layer (14) comprising n images (14l, 14r) for n = 1 to i which are visible from an n-th observation angle associated with the n-th image (14l, 14r), and n being at least 1. The images are imaged on a photoresist (16) with parallel light in contact print or by means of projection. After the photoresist (16) is developed, an image layer (14) which comprises the i images is present.
