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 (1), and/or acrylate (2) and/or
alkenyl-ether (3) and/or hydroxyl (4) 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).
