Abstract
A pressure-sensitive adhesive having greatly improved physical strength is provided by adding 5 to 30 parts by weight of a block copolymer of the type - A - B - A - to 100 parts by weight of a conventional tacky viscoelastic pressure-sensitive adhesive. The resulting reinforced adhesive can be used in sheet form as a transfer adhesive without fibrous reinforcement or where a high strength adhesive is desired.
