ABSTRACT:
The present invention provides a reinforced tape including a visually transparent backing layer, a reinforcing scrim preferably of fibers made of visually transparent material along one surface of the backing, and a layer of transparent adhesive covering but not totally wetting the reinforcing scrim so that the scrim is visible along the backing layer before the tape is applied to give a user a visual indication of the strength of the tape. The indexes of refraction of the material of the fibers in the scrim and of the adhesive are similar so that when the layer of adhesive is pressed against a substrate through the backing layer, the adhesive will more totally wet the fibers of the reinforcing scrim, causing them to become significantly less visible in the reinforced tape adhered to the substrate.
