Abstract
Masking tapes that changes color when the tape is rubbed down or dispensed onto an adherend and methods of making such tapes are disclosed herein. The tape includes a backing, a layer of adhesive on the bottom surface of the backing, and a release structure on the top surface of the backing that includes a pressure-chromic indicator and a release layer. The pressure-chromic indicator is characterized in that it is not activated by the pressure applied during the manufacturing process, but is activated by the pressure applied when the tape is rubbed or dispensed onto an adherend.
Claims14
A masking tape comprising:
- a backing having a top surface, a bottom surface, and at least a first edge extending between the top surface and the bottom surface;
- a layer of adhesive on the bottom surface of the backing;
- and
- a release structure on the top surface of the backing, the release structure comprising:
- a pressure-chromic indicator and a release layer;
- wherein the pressure-chromic indicator is not activated by the pressure applied during the manufacturing process, but is activated by the pressure applied when the tape is rubbed or dispensed onto an adherend.
A method of making an adhesive tape comprising:
- providing a backing that has a top surface, a bottom surface, and at least a first edge extending between the top surface and the bottom surface;
- applying a layer of adhesive onto the bottom surface of the backing;
- and
- applying a release structure on the top surface of the backing, the release structure comprising:
- a pressure-chromic indicator and a release layer;
- wherein the pressure-chromic indicator is not activated by the pressure applied during the method of making, but is activated by the pressure applied when the tape is rubbed or dispensed onto an adherend.
