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.

Multi-layer, flexible transfer tape

A flexible, multilayered transfer tape is described which contains an auxiliary support, a layer of pressure-sensitive adhesive and a binder containing a white-pigmented transfer layer having greater adhesion to the pressure-sensitive adhesive layer than to the auxiliary support. The transfer layer, which contains a binder in addition to a white pigment, is present between the auxiliary support and the pressure-sensitive adhesive layer. The transfer tape is characterized in that a non-white pigment is present in finely dispersed form in either or both of a polymer-bonded interlayer and the pressure-sensitive adhesive layer. The polymer-bonded interlayer may be situated between the white-pigmented transfer layer and the pressure-sensitive adhesive layer or in the white-pigmented transfer layer itself. Such transfer tapes have significantly improved covering capacity as compared to transfer tapes in which only the white-pigmented transfer layer is tinted.

Flexible, multilayered transfer tape

Multi-layer, flexible transfer tape comprising polymeric hollow

A multilayer flexible marking tape for use in highlighting text or applying colored markings to a paper substrate in which a relatively thin cover layer is applied to a carrier which can be stripped from the cover layer and a relatively thick pressure contact adhesive is applied to the cover layer to adhere to the substrate. The adhesive layer contains a coloring agent, preferably a fluorescent pigment.
