A pressure sensitive thermosetting adhesive that is the polymerization product of a blend that includes: (a) a polymerizable monomeric or prepolymeric syrup comprising: (i) 10-80 parts by weight of an acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 0 °C; (ii) 20-90 parts by weight of a non-polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of no greater than 10.50 and a Tg greater than 15 °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 Tg greater than 15 °C; and (b) one or more thermosetting resins. |
