Abstract
A microencapsulated pigment including a leuco dye system is incorporated as one or more layers in a roll of adhesive tape. The tape is applied and may be rubbed by hand or another object to induce a color change. The change may serve as an indicator that the tape is well adhered for masking purposes in a painting operation, or to present a design where only selected portions of the tape are rubbed to induce the color change. The microencapsulated pigment may be constructed so that the color change is irreversible or reversible.
Claims12
A roll of tape comprising;
- an elongate substrate formed in a roll, the substrate presenting a first face and a second face remote from the first face;
- an adhesive layer covering the first face of the substrate;
- and
- a microencapsulated thermochromic pigment intermixed with at least one member of the group consisting of
- (1) the adhesive layer,
- (2) a first coating bonded directly to the first face of the substrate and which is interposed between the substrate and the adhesive layer;
- and
- (3) a second coating bonded directly to the second face of the substrate,
- wherein the microencapsulated thermochromic pigment is responsive to at least one of temperature and pressure to provide a marking that is visible from a perspective encompassing the second face of the substrate.
