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