Abstract
Removable pavement-marking sheet material incorporates a stretchable porous fibrous web, such as a nonwoven web of randomly distributed fibers, preferably embedded in a pressure-sensitive adhesive layer carried on a backing. The fibrous web comprises closely spaced durable weather-resistant fibers and exhibits good tear strength in any direction. The complete sheet material exhibits a high tensile strength and a low residual force after stretching, i.e., a low force tending to retract the sheet material back to its prestretched dimensions.
