<p>Organic release agents having a moderate peel strength are known, but in general have one or more of the defects that they are difficult to prepare, are insufficiently soluble in suitable solvents, have low softening points, tend to migrate, and are difficult to modify. …<??>The invention provides a release agent having a good balance of properties comprising (A) a polymer of at least one vinyl monomer of the general formula… CH2=CR1COO(CH2CHR2O)nCONHR (I)… wherein R1 and R2 each represents hydrogen or methyl, R represents alkyl of at least 12 carbon atoms or fluoroalkyl of at least 6 carbon atoms, and n is an integer of from 1 to 6… (B) a copolymer of at least one vinyl monomer of general formula (I) above and another compound copolymerizable therewith, or a mixture of said polymer (A) and said copolymer (B). The invention also provides a product prepared by coating the release agent on the non-adhesive surface of an adhesive article having an adhesive surface and a non-adhesive surface or on the surface of a release paper.</p> |
