PURPOSE:To provide an aquatic antifouling agent containing a specific naphthothiazoledione compound as an essential active component, and exhibiting excellent adhesion-inhibiting effect against the microorganisms, algae and animal adhering to the surface of ship bottom, fishing net and various constructions in sea water or fresh water. CONSTITUTION:The objective agent contains the naphthothiazoledione compound of formula I (R1 is H, 1-8C alkyl, cycloalkyl, alkenyl, alkynyl, phenyl, halogenated alkyl, halogenated phenyl, aminated phenyl, etc.; X is H, halogen, nitro, amino or acetylamino; n is 1-4), formula II (R2 and R3 are same as R1), formula III (R4 and R5 are same as R1) or formula IV (R7 and R8 are same as R1), e.g. naphtho[2,3-d]thiazole-4,9-dione, as an active component. The active component is used in the form of a paint, solution, emulsion, etc., and applied to the treating object by air-spraying, brush-coating, roller-coating, etc., or fishing net is dipped in the solution, etc., of the agent.

Currently, the bottoms of ships, undersea communication cables, transportation pipelines, observation buoys, buoys, oil fences, silt protector-1 piers, thermal or nuclear power plant cooling channels, industrial cooling channels, heat exchangers, aquaculture fishing nets, fixed fishing nets, When various equipment and structures related to marine development and marine civil engineering work are immersed in water for a long period of time, they may be exposed to mussels, fujibo, etc.
Sessile animals such as Serpura, Magago, hydrozoa, bryozoans, sea squirts, and sponges, algae such as Aona, Aonori, Shiomidoro, Hibimidoguchi, Shiogusa, and Mil, and slime-forming microorganisms such as cyanobacteria, diatoms, and bacteria. In addition to problems such as vessel operational problems, poor handling, decreased buoyancy, deterioration of structures, decreased seawater inflow, and decreased cooling efficiency, in aquaculture fishing nets, the seawater inflow due to mesh clogging is also a problem. This causes a variety of harmful effects, such as the death of farmed fish, the development of parasites, and the proliferation of bacteria, causing damage to fish due to Nocardia disease and Benedeniasis.

However, although (a) heavy metal oxides such as steel and mercury have an inhibitory effect on attached animals, they have almost no effect on algae and attached microorganisms, and (c) organic chlorine compounds and carbamic acid compounds Although bryozoans have an inhibitory effect on deposits, they are selective and have little effect on fujibushi, and (c) organotin compounds are not effective against heavy metals such as steel and mercury. (d) Although arsenic compounds have sufficient effects on animals, they are extremely irritating and toxic to humans, making them difficult to use. (e) The use of chlorine or formalin causes corrosion to the cooling device and is not effective in preventing biological fouling. Japanese Patent Publication No. 47-20832 and Japanese Patent Publication No. 55-3 using 1,4-naphthoquinone derivatives
The inventions of No. 5072 and Japanese Patent Publication No. 56-4525 are also found to have an antifouling effect on large adherent organisms, but no significant effect is seen on adherent microorganisms such as bacteria.

As explained in detail above, the underwater antifouling agent of the present invention is effective not only against adherent animals and algae in water, but also against adherent microorganisms such as slime-forming diatoms and bacteria, which have been extremely difficult to control. It is clear that it also has excellent antifouling performance.
