发明名称 Process for the manufacture of pressure sensitive adhesive labels imprinted on both sides and the assembled products
摘要 The invention provides a process for making an assembly of self-adhering, pressure sensitive labels wherein a facestock of continuous printable sheet material is first printed and overcoated with a silicone polymer acting as a release agent on its obverse side and is next printed and overcoated with a waterborne, pressure sensitive polymer adhesive on its reverse side, the imprinted and coated sheet material then being assembled into a coiled sheet roll or into a layered stack of selected lengths thereof, such that the first (obverse) side of one length of sheet material is placed in substantially contiguous contact with the opposing second (reverse) side of each subsequently assembled length of sheet material. The resulting label package does not require additional silicone release sheets, and the continuous sheet can be perforated and/or cut during assembly to provide a packaged supply of tear-off labels. The labels are particularly useful for commercial use on glass windows, door panels or the like, which are often exposed to severe weathering conditions and which require labels to be visible from both sides and to remain capable of being easily peeled off and removed.
