Abstract
A method for making a novel assembly of laid-on labels, without die-cutting, is described. The method comprises printing over the release surface of a temporary carrier web a liquid pressure-sensitive adhesive in a predetermined pattern of discrete label areas separated by intervening areas of the carrier, solidifying the adhesive surface, forming a continuous film of radiation polymerizable liquid over each adhesive area, the film over each area being unconnected to films over adjacent areas, and exposing the films to radiation sufficient to solidify them by polymerization. Preferably the films extend over the edges of the adhesive and comprise liquids which do not wet the release surface.
Claims22
The method of making, without die-cutting, a series of discrete laid-on labels removably adhered to a temporary carrier web having a release surface, said labels being spaced apart on said carrier web in a predetermined pattern of label areas and intervening areas separating adjacent label areas, each label comprising a pressure-sensitive adhesive in removable contact with said release surface and a label base layer over said adhesive, said method comprising:
- (a) advancing said carrier web along a path;
- (b) applying said adhesive in liquid form to said carrier release surface in said predetermined pattern of label areas;
- (c) solidifying at least the surface of said adhesive;
- (d) thereafter forming over the surface of said adhesive in each label area a continuous film of radiation polymerizable liquid, the film over each area being substantially unconnected to the films over adjacent areas;
- and,
- (e) exposing said polymerizable liquid to radiation sufficient to convert it by polymerization to a solid, the polymerized continuous film forming said label base layer over said adhesive.
The method of making, without die-cutting, a series of discrete laid-on labels removably adhered to a temporary carrier web having a release surface, said labels being spaced apart on said carrier web in a predetermined pattern of label areas and intervening areas separating adjacent label areas, each label comprising a pressure-sensitive adhesive in removable contact with said release surface and a label base layer over said adhesive, said method comprising:
- (a) advancing said carrier web along a path;
- (b) applying said adhesive to the carrier release surface in said predetermined pattern of label areas without application to said intervening areas by printing thereon a liquid polymerizable by radiation to form said adhesive;
- (c) exposing said liquid to polymerizing radiation sufficient to solidify at least the surface thereof;
- (d) thereafter forming on said web a continuous film over said adhesive and a discontinuous film over the exposed release surface of said intervening areas by applying to the surfaces of both said adhesive and exposed release surface at least one layer of radiation polymerizable liquid, said liquid wetting the exposed surface of said adhesive but not the exposed release surface, the liquid forming over said exposed release surface by surface tension beads of liquid substantially unconnected to the continuous films of liquid over said adhesive;
- (e) exposing said liquid continuous films to a source of radiation sufficient to convert them by polymerization to solid layers, the continuous films forming said label base layers over said adhesive;
- and,
- (f) printing indicia over said label base layers.
An assembly of laid-on labels comprising a temporary carrier having a release surface, and a plurality of discrete labels removably adhered to said release surface, each label comprising a pressure-sensitive adhesive in contact with said release surface and a continuous label base layer over the adhesive, said label base layers extending at least partially over the edges of said adhesive to limit ooze thereof and comprising radiation polymerized polymers, said labels being individually removable from said carrier.
An assembly of laid-on labels comprising a temporary carrier web having a release surface, a plurality of discrete labels removably adhered to said release surface, each label comprising a pressure-sensitive adhesive in contact with said release surface and a continuous label base layer over said adhesive, said labels being spaced apart on said carrier in a predetermined pattern of label areas and intervening areas separating adjacent label areas, said label base layers comprising radiation polymerized polymers, and over said intervening areas of the carrier, discontinuous areas of radiation polymerized polymers identical in composition to said label base layers, said discontinuous areas of polymerized monomers being substantially unconnected to said continuous label base layers, said labels being individually removable from said carrier.
