## Abstract

A process for preparing a biocidal, bactericidal and/or bacteriostatic material including the preparation of a polymer precursor solution that has (a) at least one monomer A having a porphyrin group and at least one radical polymerizable function, (b) at least one radical polymerizable monomer B, a photoinitiator, and (c) at least one of the monomers chosen from a monomer C having a quaternary amine and a radical polymerizable function; and/or a monomer D having copper and a radical polymerizable function. Also, the material obtainable by the process and its uses.

## Claims

### Claim 1

A biocidal, bactericidal and/or bacteriostatic material comprising a support impregnated with a biocidal, bactericidal and/or bacteriostatic polymer matrix resulting from the radical polymerization of a precursor polymer solution, the precursor solution comprising the mixture of: (a) at least one monomer A having a porphyrin group and at least one radical polymerizable function, (b) at least one radical polymerizable monomer B, (c) a photoinitiator, (d) at least one of the monomers chosen from: a monomer C comprising a quaternary amine and a radical polymerizable function; and/or (ii) a monomer D comprising copper and a radical polymerizable function, (e) optionally, a solvent.
