Backlit decorative surface, particularly for the interior finishing of motor vehicles

Planar decorative material for vehicle interiors having an upper, visible side, and a lower side that is attached to an illumination device, the planar decorative material comprising:

• a) a first layer having an upper surface and a lower surface, the upper surface is the upper, visible side of the planar decorative material, and,
• b) a second layer having an upper surface and a lower surface, and the upper surface of the second layer is attached to the lower surface of the first layer, and,
• c) perforations that penetrate completely through both the first layer and the second layer, and,
• d) the lower surface of the second layer attached to the illumination device, such that a part of a light from the illumination device passes through the first layer and the second layer, and, out the visible surface of the planar decorative material, and,
• e) the second layer, is an adhesive film, that is activated by an increase in temperature and/or pressure, and the second layer is pre-laminated onto the lower surface of the first layer by application with increase to a first temperature T1, which is lower than a second temperature T2, and/or a first pressure increase to P1, which is lower than or equal to a second pressure P2, and,
• f) the second layer is permanently bonded onto the illumination device under an increase in temperature to temperature T2 and/or increase in pressure to pressure P2.
