ABSTRACT:
Directly printable tape comprising a polymeric film backing having a low adhesion backsize coating on one major surface thereof and a pressure-sensitive adhesive on the other major surface thereof. The low adhesion backsize coating comprises a mixture of a low adhesion backsize compound and an ink adhesion promoter. Also, a method of printing on the low adhesion backsize coating and an ink composition. The ink comprises a conventional flexographic ink composition containing an ink adhesion promoter. The tape is heated to a temperature sufficiently high to soften the backsize coating but not so high as to distort the polymeric backing or degrade the adhesive, with the ink being applied while the backsize coating is in a softened state.
