Abstract: A monolayer polyolefin-based printable article includes 0.1 to 5% by weight of at least one polyaminoalkylene, and is characterized in that it has been treated by means of an oxidative surface treatment, such as a corona treatment. A process for the manufacture of a polyolefin-based printable article, according to which at least one surface region of the article, including at least one polyolefin and from 0.1 to 5% by weight of at least one polyaminoalkylene, involves subjecting the region to an oxidative surface treatment. A printing process, according to which a polyolefin-based article, including from 0.1 to 5% by weight of at least one polyaminoalkylene and treated by means of an oxidative surface treatment, utilizes an electrophotography technique to print on the article.

Abstract: The invention relates to an article of which at least one surface zone comprises at least one polyolefin and has been printed by means of a toner by an electrophotographic technique, characterized in that the printed zone contains no toner printing primer and in that the adhesion of the toner to the article is such that it withstands a stripping force of at least 0.4 N/mm exerted by means of an adhesive tape. It also relates to a process for the manufacture thereof.

Abstract: The invention relates to a flexible composition comprising a vinyl chloride polymer and a block copolymer. The latter comprises a poly(ethylene oxide) block and a block of a polymer which is miscible with the vinyl chloride polymer, other than the latter itself. The invention also relates to a poly(ethylene oxide)/poly-.epsilon.-caprolactone diblock copolymer which can be used in this composition, as well as to the use of this composition for the manufacture of an article and to an article comprising this composition.

Abstract: The invention relates to a process for the surface treatment of at least one portion of an article comprising at least one plastic material, the process comprising a step of fluorination for out most 12 seconds, following a step of an energetic surface oxidation of this portion.

Abstract: 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.

Abstract: Process for the surface treatment of at least a part of an article comprising at least one surface essentially composed of a plastic, the said process comprising at least one sulphonation stage and at least one neutralization stage and being characterized in that the neutralization is carried out by bringing into contact with at least one polyamine compound.
