Abstract
Disclosed is a method for making a substrate coated with an adhesive, comprising applying an electron beam modifiable adhesive layer onto a repeatably reusable transfer surface, irradiating the adhesive layer with an electron beam to chemically modify the adhesive layer, and transferring the irradiated adhesive layer to a substrate. Also disclosed is an adhesive coated web, comprising a substrate having at least one component susceptible to electron beam radiation degradation having no electron beam radiation modification and an adhesive layer having an electron beam modified composition and having no chemical, thermal, or ultraviolet crosslinking agent.
