Abstract
A pavement marking article that has an adhesive composition for adhering the article to a pavement substrate, where the adhesive composition includes a reaction product of an acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 0° C., a non-polar ethylenically unsaturated monomer, and 0-10 parts by weight of a polar ethylenically unsaturated monomer. Preferably the amount of the acrylic acid ester is about 60-90 parts by weight, and the amount of the non-polar ethylenically unsaturated monomer is about 10-40 parts by weight. Also, a raised pavement marker that comprises: Raised pavement markers that use a pressure sensitive adhesive meeting parameters (i)-(iii) can demonstrate good adhesion to roadways and are capable of withstanding repeated impacts from motor vehicle tires.
