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 and a layer of pressure-sensitive adhesive, a binder-containing white-pigmented transfer layer showing greater adhesion to the layer of pressure-sensitive adhesive than to the auxiliary support being present between the auxiliary support and the layer of pressure-sensitive adhesive, characterized in that a non-white pigment is present in finely dispersed form
A transfer tape as claimed in at least one of the preceding claims, characterized in that the non-white pigment is a black pigment.
A transfer tape as claimed in at least any of the preceding claims, characterized in that the interlayer a) is about 1 to 5 μm thick and, more particularly, about 2 to 4 μm thick.
A transfer tape as claimed in at least one of the preceding claims, characterized in that the white-pigmented transfer layer is about 15 to 25 μm thick and, more particularly, about 18 to 22 μm thick.
A transfer tape as claimed in at least one of the preceding claims, characterized in that the pressure-sensitive adhesive layer b) is about 1 to 5 μm thick and, more particularly, about 2 to 4 μm thick.
The use of the transfer tape claimed in at least one of the preceding claims in roll form in a hand-held dispenser.
