Abstract
Abstract Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The tie coating comprises a dispersion of a pigment, such as silica, with a binder, such as polyvinyl alcohol. The substrate is cut to form individual labels, and is rolled up into a roll with the release coated second face on the outside of the roll. Printing may be applied to the substrate prior to coating, or to the release coating.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
125 words
Linerless label stock, comprising: a substrate having first and second faces, wherein said substrate is insensitive to thermal effects; a pressure sensitive adhesive; a tie coat facilitating adherence of said pressure sensitive adhesive to said first face of said substrate, said tie coat adhering to both said substrate first face and said pressure sensitive adhesive; a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, and wherein the label stock has a spiral roll configuration such that the pressure sensitive adhesive adheres to the release coat to maintain the roll configuration, and wherein one or more labels of the stock may be peeled off the roll at an outer end of the roll.
Claim 2
Dependent Claim
125 words
Linerless label stock, comprising: a substrate having first and second faces, wherein said substrate is insensitive to thermal effects; a pressure sensitive adhesive; a tie coat facilitating adherence of said pressure sensitive adhesive to said first face of said substrate, said tie coat adhering to both said substrate first face and said pressure sensitive adhesive; a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, and wherein the label stock has a spiral roll configuration such that the pressure sensitive adhesive adheres to the release coat to maintain the roll configuration, and wherein one or more labels of the stock may be peeled off the roll at an outer end of the roll.
Claim 3
Dependent Claim
36 words
Stock as recited in claim 1 in a continuous, roll configuration, portions of said pressure sensitive adhesive rolled on top of portions of said release coating, with said release coating on the outside of the roll.
