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: 6
Claim 1
Independent Claim
92 words
Linerless label stock, comprising: a substrate having first and second faces; 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; and a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, wherein said tie coating consists essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water.
Claim 2
Dependent Claim
92 words
Linerless label stock, comprising: a substrate having first and second faces; 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; and a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, wherein said tie coating consists essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water.
Claim 3
Dependent Claim
106 words
Linerless label stock, comprising: a substrate having first and second faces; 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; and a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, wherein said tie coating comprises a dispersion of a pigment with a binder, and wherein said tie coating consists essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water.
Claim 4
Dependent Claim
106 words
Linerless label stock, comprising: a substrate having first and second faces; 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; and a release coat, of material that has a low adherence to said pressure sensitive adhesive, on said second face of said substrate, wherein said tie coating comprises a dispersion of a pigment with a binder, and wherein said tie coating consists essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water.
Claim 5
Dependent Claim
114 words
Linerless label stock, comprising: a substrate having first and second faces; a pressure sensitive adhesive; a tie coat enhancing 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, in continuous form over said second face of said substrate, to prevent the pressure sensitive adhesive from sticking to the second face of the substrate if brought into contact therewith, wherein said tie coating consists essentially of about 30-40 parts silica dispersion, about 20-35 parts polyvinyl alcohol, and about 30-40 parts water.
