ABSTRACT:
A noiseless, printable self-adhesive tape comprises a substrate in the form of an olefinic polymer film, a pressure-sensitive adhesive layer on one face of the substrate, and a printable, non-stick layer on the other face of the substrate. The non-stick layer is formed by a composition including a chlorinated olefinic resin and an acrylic resin in which the ratio by weight of the acrylic resin to the chlorinated olefinic resin may vary from 4:1 to 1:4. The composition also includes from 0.1 to 2 parts by weight of a non-stick agent per 100 parts by weight of the sum of the first two components, the non-stick agent being prepared by the reaction of an alkyl isocyanate with polyvinyl alcohol and a reactive silicon compound.
