摘要： A sealing film, comprising a carrier film and a plurality of functional layers comprising at least two color display layers and at least two adhesion-controlling layers, the sealing film having an adhesive layer for fastening to a base surface, the carrier film being at least partially detachable from the functional layers in order to bring the sealing film from a first state into a second state, at least one symbol arrangement being optically visible at least in a remainder in the second state, which at least one symbol arrangement is arranged in a first subregion and a second subregion. According to the invention, the functional layers and the adhesive layer are at least partially translucent and the functional layers comprise at least one additional color display layer and at least one additional adhesion-controlling layer, the functional layers being designed in such a way that the at least one symbol arrangement is optically better visible in the first subregion than in the second subregion on a light background and that the at least one symbol arrangement is optically better visible in the second subregion than in the first subregion on a dark background.

摘要： The present invention relates to a planar sealing element (1) for application to a substrate (2), comprising a carrier layer (3) and several functional layers (4),
the functional layers (4) comprising at least one colour display layer (5) and an adhesion-controlling layer (6),
the sealing element (1) furthermore comprising an adhesive layer (8) for attachment to the substrate (2),
the functional layers (4) being arranged between the carrier layer (3) and the adhesive layer (8),
wherein the carrier layer (3) is at least partially detachable from the functional layers (4) in order to bring the sealing element (1) from a first state (9) to a second state (10), with the second state (10) not being convertible into the first state (9),
the sealing element (1) in the second state (10) comprising a peeled-off layer (11), comprising at least the at least partially detached carrier layer (3), and a residue (12), comprising at least the adhesive layer (8) and at least parts of the at least one colour display layer (5),
the carrier layer (3) being made of paper, wherein it is envisaged, according to the invention, that the carrier layer (3) is translucent so that the peeled-off layer (11), in at least one area when the peeled-off layer (11) is arranged congruently on the residue (12), has a different colour impression than the same area of the carrier layer (3) in the first state (9) in a viewing direction toward the carrier layer (3).-

摘要： Sealing film for application to a base surface includes a carrier film and functional layers that include at least two color display layers and at least two adhesion-controlling layers. The sealing film has an adhesive layer for attachment to the base surface. The functional layers are arranged between the carrier film and the adhesive layer. The carrier film is detachable, at least partially, from the functional layers. In a second state at least one symbol is optically visible but not visible in a first state. The at least two adhesion-controlling layers separate defined regions from the at least two color display layers during carrier film detachment. The functional layers include at least one further adhesion-controlling layer, to make at least one layer behind the further adhesion-controlling layer, viewed from the carrier film toward the adhesive layer, visible in the second state, at least in certain sections, via the detachment.
