ABSTRACT The invention relates to a pressure-activatible correcting tape, which has a conventional carrier and a lift-off layer for removing typed or printed type images, the lift-off layer containing a wax, a binder and optionally further additives. This correcting tape is characterized in that the lift-off layer contains approximately 5 to 35% by weight of butyl rubber, approximately 30 to 90% by weight of wax and approximately 0.1 to 5% by weight of a dispersant having a dispersing action in an aqueous medium for the aforementioned substances. The lift-off layer can be produced by means of an aqueous costing liquid, which is envir- onmentally advantageous compared with organic dispersants. This corr- ecting tape can be used without restriction and independently of the type of typewriter.
