Abstract
An adhesive strip is described which comprises PA1 (A) a polymer backing sheet material; PA1 (B) a controlled adhesion coating on one surface of said sheet material, said coating comprising a radiation-cured mixture comprising PA2 (B-1) a major amount of at least one acrylate oligomer selected from amine acrylate oligomers, epoxy acrylate oligomers, urethane acrylate oligomers and acrylic acrylate oligomers, and PA1 (B-2) a minor amount of at least one monomer selected from monofunctional acrylate monomers and polyfunctional acrylate monomers, and PA1 (C) an adhesive on the other surface of said sheet material. Articles such as disposable diapers also are described which utilize the strip as a target strip or landing zone for pressure-sensitive adhesive fastening tabs when the diaper is fastened around the body.
