Abstract: Presently described are linerless sheeting articles comprising a substrate, a pressure sensitive adhesive layer disposed on the substrate, and a water soluble protective layer disposed on the pressure sensitive adhesive layer. The water soluble protective layer comprises at least 50 wt-% solids of a water soluble polymer and a polymer additive comprising a fluorinated-group, a silane group, or a combination thereof. The polymer additive is typically present in an amount no greater than 5 wt-% solids. In a favored embodiment, the polymer additive is an oligomer. Methods of making and applying the sheeting article are also described.
