Abstract
Normally tacky and pressure-sensitive adhesive tape which displays good adhesion and shear properties, even when contaminated with dust, e.g., talcum powder. The adhesive is a rubbery block copolymer (especially styrene-isoprene-styrene), tackified with a combination of certain liquid and solid tackifiers. The tape is especially useful as a closure for disposable diapers.
