Presently described are coating compositions comprising a polymerizable resin composition and a non-ionic unpolymerizable surfactant. In some embodiments, the coating comprises greater than 10 wt-% of non-ionic unpolymerizable surfactant. In other embodiments, the coating composition comprises an an additive comprising a silicone group or a fluorinated group and a hydrophobic group. Also described are articles comprising the cured coating compositions. In one embodiment, an article is described comprising a cured coating wherein the cured coating exhibits a property of an initially visible simulated fingerprint reducing in visibility in 1-20 minutes. Also described is a method of determining the fingerprint visibility of a coating composition and a polyacylate composition useful as an additive. In another embodiment a coated surface is described comprising a polymeric organic material comprising a plurality of pores wherein a portion of the pores are interconnected and comprise a lipophilic liquid.
