Abstract
Abstract A die-cut permanent marking article for use with an elongate object, consisting of a strip of low molecular weight heat-sensitive, transparent polymeric film having an upper and a lower surface, at least a portion of the lower surface being capable of self-adherence, at least a portion of the upper surface being imprintable, the polymeric film being fusible by the application of heat, but remaining transparent even after application of heat such that any marking placed on any portion of the article remains readable even if covered by one or more overwrapping portions of the strip.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
109 words
A die-cut permanent marking article for use with an elongate object, consisting of a strip of low molecular weight, heat-sensitive, transparent polymeric film selected from the group consisting of polyethylene, polypropylene, polyallomers, ethylene vinyl acetate, copolymers thereof, and mixtures thereof, having an upper and a lower surface, at least a portion of the lower surface being capable of self-adherence, at least a portion of the upper surface being fusible by the application of heat, said polymeric film remaining transparent even after application of heat, such that any marking placed on any portion of the article remains readable even when covered by one or more overwrapping portions of said strip.
Claim 2
Dependent Claim
109 words
A die-cut permanent marking article for use with an elongate object, consisting of a strip of low molecular weight, heat-sensitive, transparent polymeric film selected from the group consisting of polyethylene, polypropylene, polyallomers, ethylene vinyl acetate, copolymers thereof, and mixtures thereof, having an upper and a lower surface, at least a portion of the lower surface being capable of self-adherence, at least a portion of the upper surface being fusible by the application of heat, said polymeric film remaining transparent even after application of heat, such that any marking placed on any portion of the article remains readable even when covered by one or more overwrapping portions of said strip.
Claim 3
Dependent Claim
90 words
A marking article according to claim 1 wherein a portion of the upper surface is coated with an opaque, imprintable layer, said transparent polymeric film extending beyond said opaque layer such that a portion of the strip appears opaque, and a portion of the strip appears transparent, said polymeric film being fusible by the application of heat, said polymeric film remaining transparent even after application of heat such that any marking placed on said opaque layer remains readable even if covered by one or more overwrapping portions of said strip.
Claim 4
Dependent Claim
17 words
A permanent marking article according to claim 1 wherein said film is an ethylene vinyl acetate polymer.
Claim 5
Dependent Claim
12 words
A permanent marking article according to claim 3 further comprising a tackifier.
Claim 6
Dependent Claim
16 words
A permanent marking article according to claim 4 wherein said tackifier is a hydrogenated rosin ester.
Claim 7
Dependent Claim
24 words
A marking article according to claim 1 wherein said portion of said lower surface capable of self-adherence has been coated with a pressure-sensitive adhesive.
Claim 8
Dependent Claim
25 words
A permanent marking article according to claim 6 wherein said pressure-sensitive adhesive covers no more than 25% of said lower surface of said polymeric strip.
Claim 9
Dependent Claim
27 words
A permanent marking article according to claim 7 wherein said adhesive is selected from the group consisting of silicones, acrylics, elastomeric block copolymer adhesives, polyesters, and polyolefins.
Claim 10
Dependent Claim
15 words
A permanent marking article according to claim 8 wherein said adhesive is an acrylic adhesive.
Claim 11
Dependent Claim
18 words
A kit comprising a multiplicity of permanent marking articles according to claim 1 releasably attached to a liner.
Claim 12
Dependent Claim
