Abstract
Multi-layer flexible transfer tapes are provided which are useful for covering printing or typing errors in texts or drawings so that corrections may be made. The transfer tapes are characterized by the inclusion of two binder-containing pigmented transfer layers, wherein one transfer layer is cationic and the other transfer layer is anionic.
Claims12
A multi-layer flexible transfer tape comprising a backing, a layer of pressure-sensitive adhesive, and two binder-containing pigmented transfer layers, which are different from the layer of pressure sensitive adhesive, wherein at least one binder-containing pigmented transfer layers are present between the backing and the layer of pressure-sensitive adhesive, one of the binder-containing pigmented transfer layers is cationic, and one of the binder-containing pigmented transfer layers is anionic.
A multi-layer flexible transfer tape comprising
- (a) a backing;
- (b) an anionic binder-containing pigmented transfer layer having a thickness of about 5 g/m2 to about 25 g/m2;
- (c) a cationic binder-containing pigmented transfer layer having a thickness of about 5 g/m2 to about 25 g/m2;
- and
- (d) a pressure-sensitive adhesive layer having a thickness of about 1 g/m2 to about 5 g/m2;
- wherein the cationic binder-containing pigmented transfer layer is located between the backing and the anionic binder-containing pigmented transfer layer and the anionic binder-containing pigmented transfer layer is located between the cationic binder-containing pigmented transfer layer and the pressure-sensitive adhesive layer.
