摘要： 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.
