Abstract

This invention relates to switch-proof labels useful for marking objects in a manner such that, if one were to attempt to transfer the label to another object, the label would be destroyed or defaced to such an extent that its transference would be noticeable.

The label comprises a laminate comprising a transparent or translucent outer sheet having an information containing pattern printed on its inner surface, said printed inner surface having a coating of pressure sensitive adhesive film coated thereon.

Claims

1. A laminated label comprising:

(a) a flexible transparent or translucent plastic film, having reverse printed one side thereof a disruptable information containing pattern printed in an ink which ink is not fully dried or cured to a high cohesive integral film, and

(b) a layer of pressure sensitive adhesive bonded to the printed side of said plastic film,

the plastic film, the disruptable pattern, and the adhesive layer having relative affinities such that the affinity of the adhesive layer for the substrate to which it is applied, the affinity of the adhesive layer for the disruptable ink pattern, the affinity of the disruptable ink for the plastic film, the affinity of the disruptable ink for any conventional ink separating the disruptable ink from the adhesive layer or the cohesive strength of the adhesive layer all being greater than the cohesive strength of the disruptable pattern, with

the adhesive layer being formed from an adhesive which has at least one of the following characteristics;

(i) an adhesive which has an affinity for the surface to which the laminated label is adhered which is greater than the cohesive force of the adhesive layer,

(ii) an adhesive which has an affinity for the surface to which the laminated label is adhered greater than the affinity of the adhesive layer for said plastic film,

so that when the laminated label has been mounted on an object, attempted removal causes delamination of the label with at least a tamper indicating amount of the disruptable printed pattern remaining adhered to at least a portion of the pressure sensitive adhesive which remains on the object.

2. A laminated label, as in claim 1, which has a release sheet covering the otherwise exposed side of the pressure sensitive adhesive layer.

3. A laminated label comprising:

(a) a flexible transparent or translucent plastic film, having reverse printed one side thereof a disruptable information containing pattern printed in an ink which ink is not fully dried or cured to a high cohesive integral film, and having in turn coated or printed over the disruptable pattern a dried or cured integral ink film; and

(b) a layer of pressure sensitive adhesive bonded to the printed side of said plastic film,

6. A laminated label comprising:

(a) a flexible transparent or translucent polyester film, having reverse printed one side thereof a disruptable information containing pattern printed in an ink which ink is not fully dried or cured to a high cohesive integral film, and having in turn coated or printed over the disruptable pattern a dried or cured integral ink film, and

(ii) an adhesive which has an affinity for the surface to which the laminated label is adhered greater than the affinity of the adhesive layer for said polyester film,

so that when the laminated label has been mounted on an object, attempted removal caused delamination of the plastic film and the pressure sensitive adhesive with at least a tamper indicating amount of the disruptable printed pattern remaining adhered to at least a portion of dried or cured integral ink film which remains adhered to at least a portion of the pressure sensitive adhesive which remains on the object.

7. An object having adhered thereto a laminated label comprising:
