1. A method comprising the steps of:
- applying a UV curable pressure sensitive adhesive composition, comprising in weight percent;
(a) about 0.5% to about 10% photoinitiator agent,(b) about 20% to about 50% of a polyurethane resin with a pendent acrylate functionality, and having a molecular weight (MN) within the range of about 500 to about 2.000.000,(c) about 10% to about 55% of an acrylate monomer, having a molecular weight within the range of about 50 to about 5.000,(d) about 1/2% to about 10% of acrylated polybutadiene material having a molecular weight (MN) within the range of about 4000 to about 6000, and(e) about 0.1% to about 35% of a tackifier agent, to a substrate surface,subjecting said adhesive composition to ultraviolet radiation,positioning an object in contact with said adhesive composition to adhere said object in position on said substrate surface.
