PURPOSE:To obtain the titled composition capable of exhibiting repellent action, by respectively dissolving a mixture of an alkylbenzenesulfonic acid or polystyrenesulfonic acid with pyridazines, mixture of the former with dipyridyl or nicotines and mixture of phenols, etc., with an aliphatic aldehyde in a medium. CONSTITUTION:An antifouling composition, obtained by using a mixture of a pyridazine derivative (e.g. 3,6-dichloropyridazine) with an alkylbenzenesulfonic acid or polystyrenesulfonic acid dissolved in a medium, such as isopropyl alcohol, isobutyl alcohol, toluene or xylene or a mixture thereof, mixture of dipyridyl or nicotines with an alkylbenzenesulfonic acid or polystyrenesulfonic acid dissolved in the medium and mixture of phenols or thiophenols with an aliphatic aldehyde dissolved in the medium as essential ingredients and having repellent action on various noxious organisms. |
