Estimating the term…
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.
A multilayer flexible transfer tape comprising an auxiliary support, a pressure-sensitive adhesive layer about 1 to 5 μm thick, and a binder-containing white-pigmented transfer layer about 15 to 25 μm thick comprised of titanium dioxide having greater adhesion to the pressure-sensitive adhesive layer than to the auxiliary support which is present between the auxiliary support ad the pressure-sensitive adhesive layer, characterized in that from about 0.1 to 5% by weight of a non-white pigment is dispersed in a polymer-bonded interlayer situated between the white-pigmented transfer layer and the pressure-sensitive adhesive layer.
