Abstract

The invention relates to a packaging material with a forgery-proof security feature, whereby the security feature comprises a coded image arrangement which is provided on the packaging material and which reveals an image or image sequence by superimposing a related decoder element. The invention is characterized in that the decoder element is a transparent or translucent, film-type object with a line or column-type pattern made up of lines or columns lined up parallel to each other specific distances apart, and the image arrangement on the packaging material contains a plurality of coded individual images that mix into each other, whereby the coded individual image is an arrangement of strip-shaped image elements that are spaced apart and are co-ordinated in terms of orientation and distance from each other with respect to the line or column pattern of the decoder element, such that by overlapping the image arrangement and the decoder element and lateral displacement of the decoder element over the image arrangement, an image sequence that to the human eye appears to be moving is obtained and, depending on the position of the decoder element the coded individual images are covered or are visible by means of the window regions lying between the lines or columns and, in combination with the line or column-type pattern of the decoder element, fit together to make up recognizable images.
