Patent ID: 10629098

Abstract:
The present invention relates to peelproof security films made from a poly(meth)acrylate, more particularly from a polymethyl methacrylate, which comprises at most 10 wt % of or no impact modifiers. These films are highly transparent, have good printability qualities, and can be applied without intended break points. The peelproof security films can therefore find use in particular in documents, such as passports, for example, in security labels, such as road tax badges, for example, or for product theft prevention, or as price tags. These security labels are further distinguished by good weathering stability and in particular by especially good UV stability.The present invention relates more particularly to the use of these security labels, which have a thickness of not more than 2 mm, comprise at least 80 wt % of polymethyl methacrylate and contain no impact modification particles.
