Title of Invention

PROCESS FOR SURFACE TREATMENT OF A SOLID SUBSTRATE BY PHOTOPOLYMERIZATION TO IMPART BIOCIDAL PROPERTIES.

Abstract The present invention relates to a process for surface treatment of a solid substrate in which photopolymerisation and covalent grafting are performed in situ on said substrate of a biocidal copolymer, wherein steps are taken in which: a) said solid substrate is put in contact with a formulation comprising: 1. at least one monomer comprising a biocidal group, 2. at least one copolymerisable compound with said biocidal monomer comprising a multifunctional monomer or oligomer mono-di-or selected amongst acrylate, epoxide or vinyl ether monomers or oligomers, 3. at least one photoinitiator selected amongst radical and/or cationic photoinitiators, and 4. at least one grafting agent for grafting on said substrate, and b) photocopolymerisation and covalent grafting of the copolymers obtained are carried into effect by subjecting said formulation in contact with said solid substrate to ultraviolet radiation.
