Abstract

The invention is directed to a radiation curable adhesive composition comprising at least one vinyl modified block copolymer having a first polyvinyl aromatic block and a second polydiene block having vinyl functionality, and at least one tackifier. Optionally, the composition may comprises at least one second block copolymer that has not been vinyl modified, at least one platicizer, and at least one wax. The invention is also directed to a double-faced label formed from the composition and the method of producing said label.
