Abstract
A wet-slip resistant sheet comprises a substrate having a front surface, a back surface and a plurality of tapered protrusions, one end of each of which is bonded to the front surface of the substrate. The tapered protrusions are regularly arranged on the front surface of the substrate with a repeating pattern and each of said protrusions is surrounded with grooves which intersect each other. The wet-slip resistant sheet provides good wet-slip resistance and exhibits good clean recovery properties, and the BPN value of the sheet can be easily controlled.
