Abstract
A non-silicone release material for use with pressure sensitive adhesives, which contains a copolymer of: (1) an acrylate ester of the formula I: ##STR1## wherein x ranges from about 30 to about 50; and (2) at least one comonomer selected from a vinyl monomer, an acrylate monomer or a methacrylate monomer. Preferably, the acrylate ester is about 1 to about 25% by weight of the copolymer composition. The release material can be used as a backsize for pressure sensitive adhesives, particularly repositionable labels.
