Abstract
Polyoxymethylene articles having a surface printable with an ultraviolet-curing ink are obtained by molding a polyoxymethylene and treating the molded article by ultraviolet irradiation, corona discharge, or electron-beam radiation until the surface has an X-ray photoelectron spectrum in which the ratio of the C--O!.sub.n bond peak at 302 eV to the C--C bond peak at 305 eV, i.e., the C--O!.sub.n bond peak/C--C bond peak ratio, is at least 2.5.
