Abstract
Abstract A laminated construction having differential release characteristics is provided which will yield a self-detackifying adhesive surface upon delamination. The laminate is produced by coating a film of a polymeric material onto one side of a face stock material and then laminating this construction to an adhesive which has been coated onto a release liner. The release liner is removed and the remaining portion of the laminate is affixed to a suitable substrate utilizing the exposed adhesive surface. The polymeric material is chosen so that upon delamination of the face stock from the substrate, it remains affixed to the adhesive coating. This results in a self-detackified adhesive surface on the substrate. The laminate construction is useful for tags, labels, stickers, and the like as well as for sending credit, business, or membership cards on preprinted mailers to ultimate users. Because of the unique self-detackifying surface produced, both the face stock and substrate can be used and further handled or processed by hand or automated equipment.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A method of preparing a self-detackifying laminate construction comprising the steps of: coating of least one surface of a face stock sheet with a layer of a nonsilicone containing release polymer, applying to the coated face stock sheet a release additive in the form of a film of a nonsilicone containing polymer to form a subassembly, coating a substrate with a layer of adhesive, and laminating the adhesive-coated surface of said substrate to the release additive-coated surface of said subassembly to form a laminate, said release additive being releasable from said coated face stock sheet upon the application of a delaminating force less than the force required to separate said release additive from said adhesive or said adhesive from said substrate.
Claim 2
Independent Claim
121 words
A method of preparing a self-detackifying laminate construction comprising the steps of: coating of least one surface of a face stock sheet with a layer of a nonsilicone containing release polymer, applying to the coated face stock sheet a release additive in the form of a film of a nonsilicone containing polymer to form a subassembly, coating a substrate with a layer of adhesive, and laminating the adhesive-coated surface of said substrate to the release additive-coated surface of said subassembly to form a laminate, said release additive being releasable from said coated face stock sheet upon the application of a delaminating force less than the force required to separate said release additive from said adhesive or said adhesive from said substrate.
Claim 3
Dependent Claim
21 words
The method of claim 1 including the step of printing on one or both sides of said coated face stock sheet.
Claim 4
Dependent Claim
30 words
The method of claim 1 in which said face stock sheet is selected from the group consisting of paper, polymer films, polymeric sheets, textiles, glass, metal foils and metal sheets.
Claim 5
Dependent Claim
21 words
The method of claim 1 which said nonsilicone containing release polymer is polyethylene and said nonsilicone containing polymer is polyvinylidene chloride.
Claim 6
Dependent Claim
21 words
The method of claim 1 in which said nonsilicone containing release polymer is polystyrene and said nonsilicone containing polymer is polyvinylbutyral.
Claim 7
Dependent Claim
23 words
The method of claim 1 in which said nonsilicone containing release polymer is polyvinyl chloride and said nonsilicone containing polymer is polyvinyl alcohol.
Claim 8
Dependent Claim
28 words
The method of claim 1 in which said nonsilicone containing release polymer is a polyester and in which said nonsilicone containing polymer is a polymer of acrylic acid.
Claim 9
Dependent Claim
28 words
The method of claim 1 in which said nonsilicone containing release polymer is polyethylene and said nonsilicone containing polymer is a mixture of polyvinylidene chloride and polyvinyl alcohol.
Claim 10
Independent Claim
155 words
A method of preparing a label, tag, or business, membership, or credit card comprising the steps of: coating at least one surface of said label, tag, or business, membership, or credit card with a layer of a nonsilicone containing release polymer, applying to the coated label, tag, or business membership, or credit card a release additive in the form of a film of a nonsilicone containing polymer to form a subassembly, coating a substrate with a layer of adhesive, laminating the adhesive-coated surface of said substrate to the release additive-coated surface of said subassembly to form a laminate, printing on the exposed face of said subassembly, and delaminating the printed and coated label, tag, or business, membership, or credit card from said laminate at the interface between said coated label, tag, or business, membership, or credit card and said film of release additive to provide a detackified tag, label, or business, membership, or credit card.
Claim 11
