  • Patent number: 5883149
    Abstract: A pressure sensitive adhesive that includes:(a) the polymerization product of:(i) 25-98 parts by weight of an acrylic acid ester of a monohydric alcohol whose homopolymer has a T.sub.g less than 0.degree. C.;(ii) 2-75 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(iii) 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.; and(b) at least one tackifier that is miscible in the polymerization product at room temperature.
