Abstract
Abstract A business form having an integrated label in its top ply or other sheets advantageously includes a release sheet which is only partially covered with a release coating in order to provide a controlled release. The controlled release is provided by skiving lines which preferably remove a portion of the release coating within a border on the release sheet. The adhesive layer is thereby directly connected to both the label and the release sheet. The release coating is penetrated intermittently by the skiving lines to remove a portion of the release coating. Alternatively, a pattern of release coating of silicone or the like may be printed in a pattern so that the release coating is only intermittently provided in covering relationship over the release sheet. The provision of intermittent direct contact between the adhesive and the release sheet provides improved adhesion of the label to the liner without detracting from the functionality of the form or the label.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
249 words
A composite business form comprising: a top ply sheet having a surrounding margin, a front face and a rear face, said top ply sheet including at least one line of weakness defining a label element located within said surrounding margin, said label element having a surrounding perimeter substantially corresponding to said at least one line of weakness; a release sheet positioned adjacent said rear face, said release sheet having a top edge, a bottom edge, and a pair of side edges, at least one of said side edges extending beyond the line of weakness in the adjacent top ply sheet defining the label element; a layer of adhesive located intermediate said rear face and said release sheet and extending to a boundary positioned beyond at least one line of weakness defining the label element within the adjacent to ply sheet; and a layer of release coating located intermediate said release sheet and said adhesive layer and defined within a surrounding border with intermittent coating-free areas defined by skiving lines at intervals provided within the border to provide intermittent direct contact between the adhesive and the portion of the release sheet within the border, there being an interface between said release coating and said release sheet, at least certain of said skiving lines being defined by opposed, generally converging marginal surfaces of said release coating, at least some portions of said skiving lines extending below said interface between said release coating and said release sheet and into said release sheet.
Claim 2
Dependent Claim
249 words
A composite business form comprising: a top ply sheet having a surrounding margin, a front face and a rear face, said top ply sheet including at least one line of weakness defining a label element located within said surrounding margin, said label element having a surrounding perimeter substantially corresponding to said at least one line of weakness; a release sheet positioned adjacent said rear face, said release sheet having a top edge, a bottom edge, and a pair of side edges, at least one of said side edges extending beyond the line of weakness in the adjacent top ply sheet defining the label element; a layer of adhesive located intermediate said rear face and said release sheet and extending to a boundary positioned beyond at least one line of weakness defining the label element within the adjacent to ply sheet; and a layer of release coating located intermediate said release sheet and said adhesive layer and defined within a surrounding border with intermittent coating-free areas defined by skiving lines at intervals provided within the border to provide intermittent direct contact between the adhesive and the portion of the release sheet within the border, there being an interface between said release coating and said release sheet, at least certain of said skiving lines being defined by opposed, generally converging marginal surfaces of said release coating, at least some portions of said skiving lines extending below said interface between said release coating and said release sheet and into said release sheet.
Claim 3
Dependent Claim
56 words
A composite business form as set forth in claim 1, wherein said release coating is initially substantially continuously applied within said border, with said intermittent coating-free area being defined by said skiving lines at said intervals within said border through said release coating to expose portions of said release sheet to direct contact with said adhesive.
Claim 4
Dependent Claim
68 words
A composite business form as set forth in claim 2, wherein said border of said release coating encloses a smaller area than the area enclosed by the corresponding boundary of the layer of adhesive, whereby a substantially release-coating free zone is defined on said release sheet outside the border of said release coating in direct contact between the adhesive and the release sheet in said release coating-free zone.
Claim 5
Dependent Claim
48 words
A composite business form as set forth in claim 3, wherein said release coating-free zone substantially surrounds said border with said corresponding adhesive layer opposite said release coating-free zone extending in substantially surrounding relationship to said border for adhering said release sheet directly to said top ply sheet.
Claim 6
Dependent Claim
22 words
A composite business form as set forth in claim 2, wherein said skiving lines are intermittently spaced and substantially parallel, linear orientation.
Claim 7
Dependent Claim
18 words
A composite business form as set forth in claim 2, wherein said skiving lines are of varying depth.
Claim 8
Dependent Claim
20 words
A composite business form as set forth in claim 6, wherein said skiving lines do not perforate said release sheet.
Claim 9
Dependent Claim
32 words
A composite business form as set forth in claim 1, wherein said label element is separable along said line of weakness not completely severing said label element from said top ply sheet.
Claim 10
Dependent Claim
76 words
A composite business form as set forth in claim 1, wherein said label element is separated from said top ply sheet by a line of weakness defined by a die cutting line completely severing said label element from said top ply sheet, whereby said label element is retained in position within said line of weakness by the adhesive contact between said label element and said release sheet and said release sheet and said top ply sheet.
Claim 11
Dependent Claim
216 words
A composite business form comprising: a top ply sheet having a front face and a rear face and including a detachable label portion defined by at least one line of weakness; a release sheet having a plurality of edges and positioned adjacent said rear face; a layer of adhesive located intermediate the label portion of the top ply sheet and the release sheet; and a layer of release coating located intermediate said release sheet and said adhesive layer and defined within a surrounding border, said border having at least one dimension extending on said release sheet beyond the corresponding and opposing line of weakness, said layer of release coating including intermittent coating-free areas within said surrounding border for direct contact between said adhesive and said release sheet, said intermittent coating-free areas being defined by skiving lines at intervals provided within said border to provide intermittent direct contact between the adhesive and the portion of the release sheet within the border; there being an interface between said release coating and said release sheet, at least certain of said skiving lines being defined by opposed, generally converging marginal surfaces of said release coating, at least some portions of said skiving lines extending below said interface between said release coating and said release sheet and into said release sheet.
