Abstract
Described is a multi-layer, flexible transfer tape with a backing and an adhesive layer, wherein between the backing and adhesive layer a bonding agent-containing transfer layer is provided, which adheres more strongly to the adhesive layer than to the backing. With this a) the bonding agent-containing transfer layer and/or b) the adhesive layer contains fine hollow particles and a water-soluble, solid alcohol. Furthermore the invention relates to a suitable process for producing such a transfer tape as well as to special application possibilities of same, in particular in rolled-up form in a hand apparatus. In particular, when used it leads to a transferred layer in which fractures, in particular micro-cracks, are excluded, and in an improvement of the initial adhesion when the transfer tape is used again after it has been stored for a long time.
