Pressure-sensitive adhesive tape having low adhesion backsizes and release coatings that can be written on with solvent and water-based inks, the indicia remaining firmly bonded and resisting smearing. The coatings comprise copolymers of (A) free radically polymerizable vinyl monomer, (B) polar monomer in sufficient amount to impart a hydrated Tg of -15.degree. C. to 35.degree. C. and a difference of at least 20.degree. C. between the hydrated and actual Tgs, and (C) siloxane-based polymer of a type and in an amount that will impart a satisfactory release value.
