Film and method for producing same

摘要

A film and a process for its production includes a light-permeable replication lacquer layer with a diffractive relief structure formed in a first side of the replication lacquer layer, a light-permeable color 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. In areas of the film where the color lacquer layer and the reflective layer overlap, the color lacquer layer is arranged between the replication lacquer layer and the reflective layer.

主权项

1. 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, andwherein the colour lacquer layer is formed in a pattern or as a grid, andwherein:i) a distance between adjacent pattern or grid elements of the colour lacquer layer lies in a range of from 50 to 250 μm, and/orii) 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, and wherein the colour lacquer used to form the colour lacquer layer is more strongly dyed if the overlaying of the surface of the relief structure with the colour lacquer layer is less.
