Abstract
Abstract Self adhesive tapes and labels especially suitable for security purposes comprise by way of example a conventional release layer 1 whereby the tape may be rolled into or unrolled from a spiral form, an ink layer 2 visible under ultraviolet light, applied as an expanse of ink, a pattern or one or more alphanumeric characters or other markings; a support substrate 3 typically consisting of UPVC, a conventional primer layer 4, and a conventional pressure-sensitive adhesive layer 5. As an alternative the ink which is visible under ultraviolet light can be printed upon the under surface of the substrate provided that this is transparent. Such tapes or labels can be used for packaging or labelling as a security feature which is visible under ultraviolet light but not otherwise visible.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
39 words
A length of thin flexible polymeric or cellulosic substrate coated on one face with a pressure-sensitive adhesive and exhibiting an indicium of an ink which has an altered visibility, or a sole visibility, under applied light of non-visible wavelength.
Claim 2
Dependent Claim
39 words
A length of thin flexible polymeric or cellulosic substrate coated on one face with a pressure-sensitive adhesive and exhibiting an indicium of an ink which has an altered visibility, or a sole visibility, under applied light of non-visible wavelength.
Claim 3
Dependent Claim
18 words
A length of coated substrate as claimed in Claim 1 in the form of a roll of tape.
Claim 4
Dependent Claim
21 words
A length of coated substrate as claimed in Claim 1 in the form of a roll of labels separated by perforations.
Claim 5
Dependent Claim
26 words
A length of coated substrate as claimed in any of Claims 1 to 3, in which the substrate is from 20 to 60 microns in thickness.
Claim 6
Dependent Claim
34 words
A length of coated substrate as claimed in any one preceding claim in which the ink consists of, or comprises as the component of a mixture, material which is invisible except under ultraviolet light.
Claim 7
Dependent Claim
27 words
A length of coated substrate as claimed in Claim 5 in which the substrate material is UPVC (unplasticised polyvinyl chloride) and the ink is soluble in methylethylketone.
Claim 8
Dependent Claim
17 words
A length of coated substrate as claimed in Claim 6 in which the ink is AN 69292.
Claim 9
Dependent Claim
32 words
A length of coated substrate as claimed in any one of Claims 1 to 5 in which the substrate material is polypropylene or polyester and the ink is soluble in n-propyl alcohol.
Claim 10
Dependent Claim
29 words
A length of coated substrate as claimed in any one preceding claim in which the ink is printed on that face of the substrate further from the adhesive layer.
Claim 11
Dependent Claim
32 words
A length of coated substrate as claimed in any one of Claims 1 to 8 in which the ink is printed on that surface of the substrate closer to the adhesive layer.
Claim 12
Dependent Claim
40 words
A method of manufacture of a length of coated substrate as claimed in Claim 1 in which the ink is printed upon the substrate before, during the course of, or subsequent to other printing visible under the normal light spectrum.
Claim 13
Dependent Claim
30 words
A method as claimed in Claim 11 in which the ink is printed upon the substrate in a supplemental or replacement printing station within a sequence of different printing stations.
Claim 14
Independent Claim
13 words
A method as claimed in Claims 11 or 12 using flexographic printing procedures.
Claim 15
Independent Claim
45 words
A method of security marking of articles such as packages in which a coated substrate as claimed in any one of claims 1 to 10 in the form of a tape or label is applied to the article as a fastening, identifying or decorative feature.
