A pressure sensitive adhesive that includes the polymerization product of: (a) 25-97 parts by weight of an acrylic acid ester of a monohydric alcohol whose homopolymer has a T.sub.g less than 0.degree. C.; (b) 3-75 parts by weight of a non-polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of no greater than 10.50 and a T.sub.g greater than 15.degree. C.; and (c) 0-5 parts by weight of a polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of greater than 10.50 and a T.sub.g greater than 15.degree. C. The relative amounts of the acrylic acid ester, the non-polar ethylenically unsaturated monomer, and the polar ethylenically unsaturated monomer are chosen such that the 90.degree. peel adhesion of the pressure sensitive adhesive to a surface provided with 1.5.+-.0.25 mg/in.sup.2 oil is greater than zero after a 10 second dwell at room temperature as measured according to Test Procedure B.
