Heat resistant brittle films can be made from impact-modified poly(meth)acrylimide, and forgery prevention labels can contain the heat resistant brittle films. The films can be advantageously prepared by extrusion and, depending on the desired purpose, can be designed to be transparent, translucent, or entirely non-transparent, e.g., white. Ideally, the brittle films and the forgery prevention labels containing the brittle films have no intended break points such as slits, perforation, etc.

Forgery prevention labels for high-temperature applications

An extruded matt foil has at least one layer in which glass beads are uniformly distributed in a polymer matrix with at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).
