A method is disclosed for increasing the adhesion of a radiation-curable coating composition to a surface which comprises treating the surface with a fluorine-containing gas before application of the coating and curing the coating composition by exposure to radiation. The increased adhesion of radiation-curable pigmented coating compositions to treated magnetic recording structures, such as tapes and disks, is particularly contemplated.

Radiation-curable coating compositions applied to fluorine-treated

Nonvolatile plasticizers are provided which are the carboxyl-functional amide reaction product of: (1) a secondary amine-functional adduct of an acrylate compound, like 2-hydroxyethyl acrylate or a monohydric caprolactone monoacrylate, and about one amine equivalent per acrylate group in the acrylate compound, of an organic primary amine such as a polyoxypropylene monoprimary amine having a molecular weight in the range of about 50 to about 8000; with (2) a dicarboxylic acid anhydride, like phthalic anhydride. These plasticizers have improved wetting properties and are particularly useful in nitrocellulose compositions, such as nail polish.
