Claim Text:
1. A crosslinkable pressure sensitive adhesive composition comprising: (A) a tackifier; (B) a cross-linking agent; and (C) a crosslinkable copolymer in an inert solvent selected from the group consisting of ethyl acetate and heptane, wherein the crosslinkable copolymer is prepared by copolymerizing: (a) 1-7 mole % of a first monomer, which is a glycidyl acrylate or glycidyl methacrylate, (b) a combination of (c) 2-6 mole % of a third monomer selected from the group consisting of isobornyl acrylate, benzylmethacrylate, tetrahydrofurfuryl methacrylate and mixtures thereof; based on the total mole % of the copolymer; wherein the molar ratio M13 of the first monomer to the third monomer is in the range of 0.1 to 1.5; wherein the combined total weight percent of the (b)(i) acrylic acid and the (a) first monomer content ranges from 6.32 wt % to 11.96 wt %, based on the total weight of the copolymer; wherein the copolymer has a glass transition temperature (Tg) of 0° C. or less; and wherein the copolymer remain stable and does not form a gel after a period of 8 weeks at 40° C., under exclusion of atmosphere.
