Abstract: A pressure-sensitive adhesive tape comprising a plurality of superimposed layers, at least one outer layer being a pressure-sensitive adhesive layer, contiguous layer defining an interface therebetween, each of said layers comprising a photopolymerized matrix of polymeric chains; said polymeric chains extending from the matrix of one of said layers through said interface into the matrix of a contiguous layer; said polymeric chains comprising polymerized monomers having migrated from the matrix of each contiguous layer prior to polymerization, whereby said layers cannot be delaminated.

Abstract: A pressure-sensitive adhesive transfer tape of the prior art has an adhesive layer containing uniformly dispersed glass monofilaments which randomly cross each other but are predominantly oriented in the lengthwise direction of the tape and generally lie in straight lines. In contrast, the monofilaments of the transfer tape of the present invention are organic and have a randomly disposed, individually arcuate configuration as shown in FIG. 2. Unlike the prior tape, the novel tape can have high adhesion and shear values and yet be dispensed from an ordinary adhesive transfer gun.
