Abstract
A multilayer pressure sensitive correction tape useful for masking handwritten and/or printed characters comprising a release liner, a masking layer and a pressure sensitive adhesive layer, wherein at least one of the layers is cured by radiation. In a preferred embodiment of the invention, the masking layer and pressure sensitive adhesive layer comprise formulations of reactive monomers or oligomers which are radiation-cured after the formulations are applied to the correction tape assembly. In a more preferred embodiment of the invention the masking layer and pressure sensitive adhesive layer formulations contain no volatile solvents when these formulations are applied to the correction tape assembly. The radiation-cured layers are essentially insoluble in organic solvents and water, and the radiation-cured layers exhibit improved film toughness and improved resistance to ink 'bleed through'. Additionally, the present invention is directed to a process for making such a multilayer correction tape having at least one radiation cured layer.
