description | The present invention relates to pressure-sensitive adhesive constructions, and more particularly, to multilayer pressure-sensitive adhesive constructions which exhibit both good adhesion and good convertibility.
The present invention is directed toward multilayer pressure-sensitive adhesive constructions with improved convertibility and aging. In one embodiment, the multilayer constructions have one layer formed of a first adhesive composition having a first glass transition temperature, and also having a tangent delta greater than about 0.5 at 10radians per second at 20° C., and a storage modulus greater than about 3×10dynes/cmat 10radians per second at 20° C. At least a second adhesive layer is provided in the construction, the second adhesive layer comprising a second adhesive composition with a second glass transition temperature. |
