COATING COMPOSITION AND DIRECTLY PRINTABLE PRESSURE-SENSITIVE ADHESIVE TAPE COMPRISING SAME

摘要

This invention relates to pressure-sensitive adhesive tape bearing a directly printable backsize coating. Non-fibrous, film tape backings have often been found to be difficult to print directly. This invention provides a directly printable backsize coating composition for a pressure-sensitive adhesive tape comprising a layer of a low adhesion backsize compound, an ink anchoring resin, and a primer resin wherein the surface free energy of the ink anchoring resin and the primer are within about 10 percent of the surface free energy of the lower adhesion backsize compound. The backsize coating exhibits excellent properties for direct printing thereon, retention of the printed image, and satisfactory release characteristics. The tape of this invention functions in a dual capacity as a packaging tape as well as a printed identification or instructed message.
