ABSTRACT:
A two-step method is provided for the production of a pressure sensitive adhesive by radiation curing. The method comprises the steps of initially irradiating a monomer composition comprised of 65 to 100 percent by weight of monomers having a Tg<0.degree. C. to form a coatable syrup, followed by adding at least one monomer having a Tg>0.degree. C. and at least one multifunctional monomer or oligomer to said syrup, and further irradiating the mixture to form a pressure sensitive adhesive.
