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. The disclosure further involves 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.
Claims27
A printed pressure-sensitive adhesive tape comprising a backing film, the faceside thereof being coated wtih a pressure-sensitive adhesive and the backside thereof being coated with a low adhesion backsize coating comprising
- (1) at least one low adhesion backsize compound, and
- (2) a chlorinated polyolefin in an amount sufficient to promote ink adhesion,
- wherein said low adhesion backsize coating bears an inked impression and is low-force removable from said pressure-sensitive adhesive without transfer of said inked impression to said pressure-sensitive adhesive.
A printable pressure-sensitive adhesive tape comprising an oriented polymeric film backing, having a faceside and a backside, the faceside being coated with a pressure-sensitive adhesive and the backside being coated with a low adhesion backsize coating comprising
- (1) at least one low adhesion backsize compound, and
- (2) a chlorinated polyolefin in an amount sufficient to promote ink adhesion,
- said low adhesion backsize coating being ink-imprintable and low-force removable from said pressure-sensitive adhesive.
