ABSTRACT:
A reinforced adhesive stock comprising a release liner on a carrier web and an adhesive layer in contact with the release liner. The adhesive layer comprises a mixture of an adhesive such as an anaerobic pressure-sensitive adhesive and a photopolymerizable compound. The photopolymerizable compound is capable of curing upon irradiating with actinic radiation. The adhesive layer contains strips of cured photopolymerizable compound which is cured by selectively irradiating with actinic radiation selective areas in strips within the adhesive layer. The resulting form strips of cured polymers provide a reinforcement to the adhesive layer inhibiting flow of the adhesive from the release liner. Additionally, the cured polymer strips provide added cohesive strength to the adhesive layer. A method of forming such adhesive stock is also disclosed.
