Abstract
A pressure-sensitive tape is provided having a polyolefin backing, a primer comprising an elastomeric block copolymer which primer is applied from a non-aromatic hydrocarbon solvent, said tape further comprising an adhesive on the thus primed surface. Because the primer is laid down from a solution in a non-aromatic hydrocarbon solvent such as methyl cyclohexane the process utilizes an environmentally-friendly solvent.
