ABSTRACT:
In a PSA tape construction, a primer layer comprising a neutralized rosin that includes acid functionalities and, optionally, an elastomer such as a styrene-butadiene rubber, is included between a tape backing and a poly(.alpha.-olefin) adhesive layer. Bonding of the adhesive layer to the backing is greatly improved, especially during and after high temperature baking of the tape construction.
