2113646 9304858 PCTABS00020 A slip control sheeting can comprise a backing (12) having a first end and a second major surface (14, 16) and an array of protrusions (22) on the first major surface. The protrusions can be pyramids with polygonal bases or pyramidal frustums with polygonal bases. Alternatively, the protrusions can comprise posts having non-planar sides and bases on the first major surface wherein the posts taper radially inwardly from their bases to their tops, e.g., cones or conical frustums with circular bases. The sheeting can further comprise at least one of a layer of adhesive (18) on the second major surface, a reinforcing web, or a mechanical fastening component for fastening the backing to a substrate. The sheeting can be made so that it retroreflects less than about 10 percent of a beam of electromagnetic radiation which is incident at any angle to the second major surface, the electromagnetic radiation having any wavelength from about 0.39 micron to about 1,000 microns.
