Disclosed is a process for coating a surface of a substrate to make the surface antibacterial, by graft copolymerizing: (i) at least one monomer of the general formula (I): R-(A)a (I), (wherein R is a mono- or diolefinically unsaturated organic radical, preferably a hydrocarbon radical, having the valence a, A is a carboxyl group -COOH, sulfuric acid group -- OSO2OH, sulfonic acid group -SO3H, phosphoric acid group -OPO(OH)2, phosphonic acid group -PO(OH)2, phosphorous acid group -OP(OH)2, a phenolic hydroxyl group or a salt of the group, and a is 1, 2 or 3) and (ii) at least one monomer having a group which is sensitive to UV radiation, under radiative induction onto an optionally activated substrate surface. Articles coated in this way can be used in the medical or biotechnical field.
