Abstract
Abstract An antifouling composition for use in the control of noxious aquatic life comprising as an active ingredient, one or more phenol derivatives of the formula <IMAGE> wherein R is a C3 DIFFERENCE C21 saturated hydrocarbon residue; X1 DIFFERENCE X5 each is H, HO or CH3O, providing excluding the case wherein all of X1 DIFFERENCE X5 are hydrogen. This composition is useful as an antifouling paint for marine structures, ships, fishnets, buoys, industrial water system, water cooling system and the like.
