Films used as permanent coatings for processable materials, especially sheets or boards, comprise the following layers: (1) a contact layer (K) comprising polypropylene or a mixed polymer thereof containing at least 50 wt.% propylene, bonded to the outside of the substrate and comprising one or more sub-layers; (2) an adhesive layer (G); and (3) an outer layer (A) comprising a linear polyester (eg. polyethylene terephthalate (PET) or polybutylene terephthalate (PBT)) or polymethylmethacrylate (PMMA). The (K)/(A) thickness ratio is 25-0.5:1 and total film thickness is 20-1000 microns. Also claimed are (i) substrates with a permanent coatings comprising the above films and optional additional coating layers, and (ii) methods for coating substrates with these films.
