NORMALLY STICKY AND PRESSURE SENSITIVE TYPE ADHESIVE TAPE IN WHICH A LAYER OF NORMALLY STICKY AND PRESSURE SENSITIVE ADHESIVE IS APPLIED TO AND ADHESED TO A FLEXIBLE CARRIER.

摘要

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, e.g. 13, 14, the outer stratum being significantly softer than the one lying immediately beneath it. Softness is expressed in terms of cm2/dyne for 10- second shear creep compliance. The tapes are particularly suited for use in the preparation of diaper closures and identification labels for washing garments. IMAGE
