<p>PCT No. PCT/NL95/00318 Sec. 371 Date Jun. 2, 1997 Sec. 102(e) Date Jun. 2, 1997 PCT Filed Sep. 22, 1995 PCT Pub. No. WO96/09928 PCT Pub. Date Apr. 4, 1996The invention provides a light-transmitting cover foil intended to be arranged adheringly to a surface, for instance the surface of a carrier plate, optionally bearing information such as letters, numbers, images or the like, which foil consists of a laminate comprising: a first layer plastically deformable only at a relatively high first temperature, for instance in the range of 120 DEG C.-200 DEG C. and comprising for instance polycarbonate, PMMA, PVC, ABS, PP, PE, which first layer is provided before, during or after joining together to the other layers with a structure, for instance a texture and/or pattern pressed out of its main surface by exerting pressure and increasing temperature to at least the said first temperature, for instance by applying a heated profile roller; a second layer adhered thereto consisting of a dimensionally stable carrier layer comprising for instance polycarbonate, PMMA, PVC, polyester/PET, ABS; and a third layer adhered thereto which is meltable and thus thermally-activated at a relatively low second temperature, for instance in the range of 50 DEG C.-90 DEG C. and which consists of a hot-melt layer or glue layer, comprising for instance EVA, EEA, EBA, EMA, GBA or other low-melting plastics including polyolefins and copolymer esters, polyacetate esters, softened PVCs; which said layers are mutually connected by adhesive agents, for instance by making use of coextrusion.</p> |
