The release-coating composition for producing a pressure-sensitive, printable adhesive tape is constituted by a polymeric component comprising from 10 to 85 parts by weight of a ketone resin, from 0 to 80 parts by weight of a polyamide resin and from 0 to 30 parts by weight of a ketone resin modified by reaction with alkylisocyanates, and solvents for the polymeric component. For the production of a printed adhesive tape, there is used, in combination with said release-coating composition, an ink comprising, with reference to the weight of the ink form 25% to 35% by weight of a polyamide resin which is soluble in alcohols and from 0.3% to 1% by weight of a silicone polymer as a slip agent.
