  • Patent number: 5154974
    Abstract: Adhesives compositions having improved cutting properties described herein. Compositions comprise a normally tacky, pressure sensitive acrylic adhesive containing, as an additive to reduce edge flow, from about 2 to about 10 percent by weight dry basis, preferably from about 5 to about 8 percent by weight dry basis based on the weight of polymer solids, of a polydimethylsiloxane having a number average molecular weight of about 1300 to about 15000. Also disclosed are laminates comprising a facing layer coated on one side with the aforedescribed adhesive composition, and optionally a release liner. These adhesive laminates exhibit substantially reduced tendency of the adhesive to ooze at the edge when cut, without material decrease in other adhesive properties, when a multiplicity of laminate sheets is stacked and cut by means of a guillotine. Laminates herein are especially useful as drum and carton labels.

  • Patent number: 5019436
    Abstract: A label assembly comprising a releasable portion which may be used as an in-store coupon constructed of a base stock having a first and second film layer having a controlled interfacial bond therebetween which will retain the film layers in integral relationship during handling or the like, but will also allow the easy separation between the film layers when desired. The controlled interfacial bond may be termed as "controlled adhesion" which is obtained by co-extruding two dissimilar polymer layers having a controlled affinity therebetween. A pressure sensitive adhesive layer is laminated to the second film layer and is provided with a release liner for the easy handling thereof. A face stock comprising a top sheet forming an in-store coupon, for example, is then adhered to the first film layer of the base stock structure to complete the label assembly.
