Abstract
The invention relates to a film (1) and a process for its production. The film (1) comprises a light-permeable replication lacquer layer (2) with a diffractive relief structure (3) formed in a first side (21) of the replication lacquer layer (2), a light-permeable colour lacquer layer (4), formed only in areas, arranged on the relief structure (3), and a reflective layer (5), formed at least in areas, arranged on the first side (21) of the replication lacquer layer (2). In areas (63) of the film (1) where the colour lacquer layer (4) and the reflective layer (5) overlap, the colour lacquer layer (4) is arranged between the replication lacquer layer (2) and the reflective layer (5).

1-23. (canceled)
A film comprising:
- a light-permeable replication lacquer layer with a diffractive relief structure formed in a first side of the replication lacquer layer;
- a light-permeable colour lacquer layer, formed only in areas, arranged on the relief structure;
- and
- a reflective layer, formed at least in areas, arranged on the first side of the replication lacquer layer,
- wherein, in areas of the film in which the colour lacquer layer and the reflective layer overlap, the colour lacquer layer is arranged between the replication lacquer layer and the reflective layer and
- wherein the colour lacquer layer is formed in a pattern or as a grid, and
- wherein:
- i) adjacent pattern or grid elements of the colour lacquer layer have a reciprocal distance which lies in a range of from 50 to 250 μm, and/or
- ii) a line width, a dot diameter or an individual element diameter of the pattern or grid elements lies in a range of from 50 to 250 μm.
