Abstract
Abstract An identification device (10,20) having a heatshrinkable plastic substrate and a printable layer (12) over an exterior surface thereof comprising a polyester resin, calcium carbonate and a silicate compound. The printable layer forms a smooth surface for the application of alphanumeric identification indicia and retains such smooth surface upon heatshrinking of the substrate up to 50% in one direction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A heatshrinkable indentification device comprising, in combination: (1) a unidirectionally oriented plastic substrate heatshrinkable up to 50% in one direction, and (2) a printable layer over an exterior surface of the substrate comprising about 2 to 11 lbs. of dry coating per 3,000 sq. ft. of substrate of a dried coating having, on a percent by weight of solids basis, (a) 50-62% of a solvent soluble, saturated film-forming polyester resin solid, (b) 16-20% calcium carbonate, (c) 9-16% of a silicate compound, and (d) 10-18% pigment other than calcium carbonate or a silicate compound, said printable layer forming a smooth surface for the application of alphanumeric identification indicia and retaining such smooth surface upon heatshrinking of the plastic substrate up to 50% in one direction.
Claim 2
Dependent Claim
124 words
A heatshrinkable indentification device comprising, in combination: (1) a unidirectionally oriented plastic substrate heatshrinkable up to 50% in one direction, and (2) a printable layer over an exterior surface of the substrate comprising about 2 to 11 lbs. of dry coating per 3,000 sq. ft. of substrate of a dried coating having, on a percent by weight of solids basis, (a) 50-62% of a solvent soluble, saturated film-forming polyester resin solid, (b) 16-20% calcium carbonate, (c) 9-16% of a silicate compound, and (d) 10-18% pigment other than calcium carbonate or a silicate compound, said printable layer forming a smooth surface for the application of alphanumeric identification indicia and retaining such smooth surface upon heatshrinking of the plastic substrate up to 50% in one direction.
Claim 3
Dependent Claim
19 words
An identification device according to claim 1 wherein: the plastic substrate is a marker sleeve having opposed open ends.
Claim 4
Dependent Claim
24 words
An identification device according to claim 1 or 2 wherein: the pigment is titanium dioxide and the printable layer is a white opaque layer.
Claim 5
Dependent Claim
23 words
An identification device according to claim 1 or 2 wherein: the pigment includes a colored pigment to form a colored opaque printable layer.
Claim 6
Dependent Claim
37 words
An identification device according to claim 1 or 2 wherein: the printable layer includes an isocyanate compound for cross-linking the polyester resin, the isocyanate compound being present in an amount of 2-5% of the polyester resin solid.
