<p>Pressure sensitive adhesive linerless label assemblies having a primer layer and a breakaway layer capable of being separated from each other after the label is applied to a surface, thus leaving a portion of the assembly on the surface and removing the other portion. In one embodiment, the primer layer is an ethylene/acrylic acid copolymer and the breakaway layer is polyvinyl acetate. In another embodiment, the primer layer is a polyethylene emulsion and the breakaway layer is a polyurethane emulsion. In a third embodiment, the primer layer is a composition of a UV curable bisphenol A epoxy oligomer, pentaerythritol triacrylate, and a monofunctional styrene monomer, and the breakaway layer is polyvinyl acetate.</p> |
