Abstract

A label to identify an object has an inscribable layer composite for receiving a first, visible inscription to identify an object, an adhesive film for adhering the label to an object, and an active substance, which, when contacting the object surface, penetrates into and/or acts on the object surface. The active substance is disposed on the label rear side in a structured active surface layer, on, in, or underneath the adhesive film. The structured active substance layer includes a partial surface region or multiple partial surface regions of the label base surface. When the label is adhesively affixed to the object surface, the active substance on the label rear side selectively contacts the object surface in the structured active substance surface region. Within the base label surface, the structured active substance layer has the shape and/or contour of a further, initially-invisible inscription, identification or item of information.

First claim

The invention claimed is:

1. A label for identification of an object, wherein the label has the following:
a rear side,
a basic label surface,
an inscribable layer composite, in which a first, visible inscription can be formed for identification of an object having a surface,
an adhesive film, with which the label can be adhesively affixed to the object, and
an active substance, which penetrates into the surface of the object and/or acts on the surface of the object when the active substance is brought into contact with the surface of the object,
wherein the active substance is disposed on the rear side, on the adhesive film or underneath the adhesive film,
wherein the label has a structured active substance layer which is different from the adhesive film, in which structured active substance layer the active substance is disposed, wherein the structured active substance layer comprises a partial surface region or multiple partial surface regions of the basic label surface, but is left out in a remaining partial region of the basic label surface,
wherein the label is free of active substance, over an entire layer thickness of the label, in the remaining partial region of the basic label surface, which is not spanned by the structured active substance layer, so that the label, when the label is adhesively affixed to the surface of the object, selectively brings the active substance into contact with the surface of the object in the partial surface region or the multiple partial surface regions of the structured active substance layer,
wherein the structured active substance layer has a shape and/or contour configured in a form of a further inscription, identification or item of information,
wherein the label has a structured adhesion-reducing layer and/or a structured UV protection layer between the structured active substance layer and the adhesive film structured to have identical coverage with the structured active substance layer and adhering more strongly to the structured active substance layer than to the adhesive film.

2. The label according to claim 1 , wherein the contour of the structured active substance surface is configured as an inscription or marking or as a negative image of an inscription or a marking.

3. The label according to claim 1 , wherein the structured active substance layer is a transparent paint layer that contains the active substance, imprinted onto a rear adhesive film side of the adhesive film.

4. The label according to claim 1 , wherein the structured active substance layer is a paint layer that contains the active substance, imprinted onto a carrier film of the label, which paint layer is disposed on the adhesive film or underneath the adhesive film.

5. The label according to claim 1 , wherein at least one of the structured active substance layer and the contour of the structured active substance layer is configured in a form of an alphanumeric inscription or alphanumeric marking or some other motif intended to be transferred to the object.

6. The label according to claim 1 , wherein the structured active substance layer is the adhesive film and contains the active substance, wherein the adhesive film is structured over the basic label surface of the label, wherein the adhesive film that contains the active substance extends over the partial surface region or the multiple partial surface regions of the basic label surface of the label, but is left out in the remaining partial region of the basic label surface of the label.

7. The label according to claim 1 , wherein the active substance is or contains a paint solvent or a medium that changes paint in some other way.

8. The label according to claim 1 , wherein the active substance is or contains a luminescence substance that is capable of diffusion into paint.

9. The label according to claim 1 , wherein the layer composite is configured as a non-transparent, inscribable or inscribed composite film.

10. The label according to claim 1 , wherein the surface of the object is painted with a paint and the label is a label for identification of the surface of the object painted with the paint, wherein the active substance penetrates into the paint and/or acts on the paint when the active substance is brought into contact with the paint.

11. A label composite for ready-to-use inscription and dispensing of at least one label, comprising
a carrier film and
the at least one label according to claim 1 , suitable for identification of the surface of the object, wherein the label is adhesively affixed, with the rear side of the label, to a side of the carrier film that has been coated in adhesion-reducing manner,
wherein the active substance is contained in the structured active substance layer of the at least one label, wherein the structured active substance layer is disposed between the adhesive film of the at least one label and the carrier film and extends over the partial surface region or the multiple partial surface regions of the basic label surface of the at least one label.

12. A method for producing at least one label for identification of an object, wherein the method comprises the following:
making available a label film web, which has an inscribable layer composite and an adhesive film, and making available a carrier film web,
imprinting at least one active substance layer having an active substance, which penetrates into a surface of the object and/or acts on a surface of the object when the active substance is brought into contact with the surface of the object, selectively onto partial surface regions of a rear side of the label film web and/or onto partial surface regions of a front side of the carrier film web, and
joining together the label film web and the carrier film web in such a manner that the active substance layer comes to lie between the label film web and the carrier film web, and
wherein the label film web is connected with the carrier film web, wherein the label film web and the carrier film web are separated from one another over certain segments and/or during certain periods of time, in order to imprint the active substance layer, and wherein the label film web and the carrier film web are joined together again after imprinting of the active substance layer.

13. A method for producing at least one label for identification of an object, wherein the method comprises the following:
making available a label film web, which has an inscribable layer composite and an adhesive film, and making available a carrier film web,
imprinting at least one active substance layer having an active substance, which penetrates into a surface of the object and/or acts on a surface of the object when the active substance is brought into contact with the surface of the object, selectively onto partial surface regions of a rear side of the label film web and/or onto partial surface regions of a front side of the carrier film web, and
joining together the label film web and the carrier film web in such a manner that the active substance layer comes to lie between the label film web and the carrier film web,
wherein in the method, a label composite is produced, which has a label or a plurality of labels, wherein each label has the following:
a rear side,
a basic label surface,
an inscribable layer composite, in which a first, visible inscription can be formed for identification of an object having a surface,
an adhesive film, with which the label can be adhesively affixed to the object, and
an active substance, which penetrates into the surface of the object and/or acts on the surface of the object when the active substance is brought into contact with the surfa
