ABSTRACT:
The invention concerns a method for treating the surface of a plastic material comprising the following steps: (1) applying on at least one of the surfaces of the plastic material a composition with polymerizable and/or crosslinkable reactive functions comprising: 1 to 99 wt. % of at least a polymerizable and/or at least partially polymerized silicone matrix A, including (co)monomers, (co)oligomers and/or (co)polymers selected among those having oxetane functions (frA); 99 to 1 wt. % of at least a polymerizable and/or at least partially polymerized matrix B, including (co)monomers, (co)oligomers and/or (co)polymers selected among those having epoxy (α1), and/or acrylate (α2) and/or alkenyl-ether (α3) and/or hydroxyl (α4) reactive functions (frB); and efficient amount of at least a cationic or cationic and radical initiator system C; and optionally at least a sensitizer D and at least a pigment E; (2) polymerizing and/or crosslinking the treated surface under an irradiating source and/or under electron beam(s).
