    摘要: The invention relates to articles including at least one polyolefin, which are surface-treated and printed with inks for PVC, which are characterized by the surface presence of fluorine and oxygen in concentrations such that the oxygen/carbon atomic ratio (O/C), measured by ESCA spectroscopy at a depth of 1.5 nm, is at least 0.08 and that the fluorine/carbon atomic ratio (F/C) (measured in the same way) has a value of at least 90% of that of the O/C ratio and of not more than 290% of this ratio. It also relates to a process for their manufacture.
