Abstract
A pressure-sensitive adhesive tape which not only conforms well and adheres quickly to irregular substrates but also possesses excellent shear adhesion performance. These properties, normally mutually exclusive, are achieved through use of superposed plural pressure-sensitive adhesive strata, the outer stratum being significantly softer than the one lying immediately beneath it.
