Title (EN) ANTIFOULING COMPOUNDS AND USE THEREOF
(FR) COMPOSÉS ANTISALISSURES ET LEUR UTILISATION
Abstract: front page image
(EN)The present invention relates to the use of compounds which have the following general formula (I), wherein R1 and R2 are independently selected from optionally substituted aryl, optionally substituted C1 to C12 alkyl and H; and R3 and R4 are independently selected from hydroxy, optionally substituted C1 to C6 alkyl, optionally substituted phenyl and H, in a method of preventing or reducing fouling, particularly in the marine environment. The compounds of the present invention have the considerable advantage of providing the antifouling coating market with an organic alternative to the existing technology which relies heavily on the addition of copper to obtain significant antifouling effects. The compounds we have developed may be used as cheap, easy to prepare additives that do not contain metals and therefore have reduced toxicity in marine environment.
(FR)La présente invention concerne l'utilisation de composés qui ont la formule générale (I) suivante, dans laquelle R1 et R2 sont choisis indépendamment parmi aryle éventuellement substitué, alkyle en C1 à C12 éventuellement substitué et H; et R3 et R4 sont choisis indépendamment parmi hydroxy, alkyle en C1 à C6 éventuellement substitué, phényle éventuellement substitué et H, dans un procédé de prévention ou de réduction des salissures, notamment dans l'environnement marin. Les composés de la présente invention présentent l'avantage considérable de fournir au marché des revêtements antisalissures une alternative organique à la technologie existante qui repose lourdement sur l'ajout de cuivre pour obtenir des effets antisalissures significatifs. Les composés que nous avons développés peuvent être utilisés en tant qu'additifs bon marché et faciles à préparer qui ne contiennent pas de métaux et présentent par conséquent une toxicité réduite dans l'environnement marin.
