Abstract
Abstract An absorbent article for absorption of human exudate is disclosed having an absorbent, a bodyside layer, a backing layer and a skid-resistant coating applied to at least one of the layers. The coating has a coefficient of friction of greater than 1 and a Sheffield smoothness rating of greater than about 200 when utilizing a modified ASTM test. The nonadhesive coating facilitates positioning the article relative to the anatomy of a user.
