Abstract
An electroluminescent (EL) film composite for attachment in the entry region of a motor vehicle, particularly on thresholds, running boards, and doorsills. The friction wear protection is rigidly integrated into the film composite, i.e. connected with the other layers of the composite in planar manner, for example in that a friction-wear-resistant protective film is already applied during production of the composite, via gluing, hot-lamination, or a similar method. Alternatively or additionally, a friction-wear-resistant coating layer can be applied, also already during production of the composite. The EL film has an electroluminescence structure composed of a luminescent pigment layer that is disposed between a front and rear electrode layer, in each instance. The electroluminescence structure is surrounded on both sides with an insulating film, in each instance. On the underside, the composite has an adhesive layer, and is fixed in place on a carrier material with the adhesive layer. The top-side insulating film also fulfills the task of a protective film.
