TECHNOLOGY FOCUS - POLYMERS - Preferred Medium: The medium (G1) further comprises a metal drier; and the acrylic resin (0.1-20 wt.%). The medium (G1) comprises the oligomer (0.1-15 wt.%). Preferred Components: The oligomer has a molecular weight of 600-1800, and is selected from polyester oligomers, urethane oligomers, and polyester-urethane oligomers. The oligomer is selected from acrylated polyester-urethane copolymers; acrylated urethane; and/or acrylated polyester. The acrylic resin has a group of formulae R1C(O)OR, Ar1C(O)OR, Ar1R1C(O)OR and/or R1Ar1C(O)OR.Ar1=aromatic residue having up to 30C (optionally substituted with -OH, 1-4C alkoxy, 1-4C alkoxycarbonyl or carbonyl) or 5-10C cycloalkyl (which is optionally mono- or polysubstituted by 1-4C alkyl, -OH, 1-4C alkoxy, 1-4C alkoxycarbonyl or carbonyl);R1=aliphatic residue having up to 15 carbons (optionally substituted with -OH, 1-4C alkoxy, 1-4C alkoxycarbonyl or carbonyl) or 5-10C cycloalkyl (which is optionally mono- or polysubstituted by 1-4C alkyl, -OH, 1-4C alkoxy, 1-4C alkoxycarbonyl or carbonyl).Preferred Method: In the method (M1), curing the medium (G1) involves heating the medium (G1) to not greater than 204 degrees C. Curing the medium (G1) comprises contacting the medium (G1) with a metal drier; and irradiating the medium with radiofrequency radiation having a wavelength of 1.1-4 microns.
