Surface treatment of a solid substrate to impart a biocidal finish comprises photopolymerization of a coating comprising a biocidal monomer, a comonomer, a photoinitiator and a grafting agent

摘要

Surface treatment of a solid substrate comprises coating the substrate with a composition comprising a biocidal monomer, an acrylate, epoxy or vinyl ether comonomer, a radical or cationic photoinitiator and a grafting agent and exposing the coating the UV radiation. An Independent claim is also included for a solid substrate with a biocidal polymer grafted to its surface, produced as above.
