The present invention provides a hot melt acrylic pressure sensitive adhesive (PSA) comprising an acrylic polymer having units derived from one or more C1-C20 alkyl esters of acrylic or methacrylic acid and units derived from one or more vinyl esters corresponding to the formula: <CHEM> wherein R<1>, R<2> and R<3> each independently represent an alkyl group and the total number of carbon atoms in the vinyl ester is from 7 to 18. The PSA is particularly suitable for sticking objects to a low surface energy substrate.
