The invention relates to photo-crosslinkable antifouling compositions, in particular antibacterial, antifungal and anti-algae ones, which include the combination of at least one telechelic oligoisoprene of a particular formula with an agent for crosslinking said oligoisoprene. The antifouling film is obtained by applying a thin layer of such a liquid composition on a substrate and is crosslinked at room temperature by exposure to visible and/or UV radiations. The film can be used for preventing the occurrence of a biofilm on any surface in a humid or aqueous environment, and can be used as an additive for preparing materials with a view to imparting bacteriostatic and/or bactericidal properties thereto.
Compositions antisalissures, notamment antibactériennes, antifongiques et antialgues, photoréticulables comprenant l'association d'au moins un oligoisoprène téléchélique de formule particulière, avec un agent de réticulation dudit oligoisoprène. Le film antisalissures est obtenu par application d'une couche mince d'une telle composition liquide sur un support et réticulé à température ambiante sous l'action des rayonnements visibles et/ou U. V. Le film peut être utilisé pour inhiber l'apparition d'un biofilm sur toute surface placée en milieu humide ou aqueux et la composition peut servir d'additif dans la préparation de matériaux en vue de leur conférer des propriétés bactériostatiques et/ou bactéricides.
