The present invention relates to combinations of 4-bromo-2-(4-chloro-phenyl)-5- (trifluoromethyl)-1H-pyrrole-3-carbonitrile, or a salt thereof, and copper or zinc compounds which provide an improved protecting effect against fouling organisms. More particularly, the present invention relates to compositions comprising a combination of 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1H- pyrrole-3-carbonitrile, or a salt thereof, together with one or more copper or zinc compounds selected from Cu2O, Cu(OH)2, CuSO4, copper pyrithione, CuSCN, CuCO3, ZnO, ZnCl2, ZnSO4, zineb, and zinc pyrithione; in respective proportions to provide a synergistic effect against fouling organisms and the use of these compositions for protecting materials against fouling organisms. This invention thus relates to the field of protection of materials, such as underwater objects, protection of wood, wood products, biodegradable materials and coatings.

La présente invention concerne des combinaisons de 4-bromo-2-(4-chloro-phényl)-5-(trifluorométhyl)-1H-pyrrole-3-carbonitrile, ou d'un sel de celui-ci avec des composés à base de cuivre ou de zinc qui produisent un meilleur effet protecteur contre les organismes salissants. Plus particulièrement, la présente invention concerne des compositions comprenant une combinaison de 4-bromo-2-(4-chlorophényl)-5-(trifluorométhyl)-1H-pyrrole-3-carbonitrile, ou d'un sel de celui-ci, avec un ou plusieurs composés à base de cuivre ou de zinc choisis parmi Cu2O, Cu(OH)2, CuSO4, la pyrithione de cuivre, CuSCN, CuCO3, ZnO, ZnCl2, ZnSO4, le zinèbe et la pyrithione de zinc ; dans des proportions respectives afin de produire un effet synergique contre les organismes salissants et l'utilisation de ces compositions pour protéger des matériaux contre les organismes salissants. La présente invention concerne ainsi le domaine de la protection de matériaux, tels que des objets sous-marins, la protection du bois, des produits en bois, des matériaux biodégradables et des revêtements.
