Abstract

The present invention relates to a process for producing polymerized films with line texture or fingerprint texture or for producing substrates coated with polymerized films with line texture or fingerprint texture, to polymerized films, obtainable by this process, with line texture or fingerprint texture or substrates coated with polymerized films with line texture or fingerprint texture, to pigments obtainable by comminuting such films, to the use of such films, substrates or pigments as or in optical filter(s), polarizers, decorative media, forgeryproof markers, reflective media or for focusing light (in solar cells), to the use of such films as an antibacterial coating, to a forgeryproof marker which comprises such a film, and to a process for detecting forgeryproof markings.
