Description of the Related Art When aquatic organisms such as barnacles, serpula, sea squirts, bryozoans, oysters, and squid stick to the bottom of ships, problems such as an increase in weight, an increase in water flow resistance, a decrease in cruising speed, and the like, shorten the life of the ship, It causes industrial problems such as increased fuel consumption. Methods for preventing the attachment of these aquatic organisms have been studied for a long time, such as biological methods using natural enemies of the organisms causing the attachment, the use of structural materials that are difficult to attach (for example, the use of copper alloys, silicone-based Paint, fluorine-based paint, etc.), prevention of larvae inflow (eg, screen shielding), control of larvae (eg, use of light, ultraviolet rays, color, ultrasonic waves, temperature rise, lack of oxygen, etc.) Environmental considerations), mechanical removal of attached organisms (e.g., washing, jet cleaning, brushing, aspiration, etc.), chemical or biochemical methods (e.g., use of shell killing, repelling, antifouling agents, etc.) are being considered. ing. Recently, the method of applying hull bottom paint containing shellicides, repellents, antifouling agents, etc. has been widely adopted and studied because of its wide application area, high effect, and easy treatment. Have been. However, paints containing these chemicals are designed so that the drug in the paint film gradually elutes into the water, or the paints containing the chemicals are gradually scraped and dissipated into the water, always exposing a new painted surface. It has been pointed out that there are concerns about adverse effects on the marine environment. In particular, in the 1980s, when it was pointed out that tin compounds, which are the most representative antifouling agents, contaminate fish and shellfish, various regulations were applied to tin-containing hull bottom paints in various European countries and the United States, which replaced aquatic aquatic substances. The development of methods for preventing biological pollution has emerged as an urgent issue. However, at present, no effective method has been developed to replace the antifouling ship bottom paint containing an antifouling agent and the like. Research is directed exclusively to the development of low-toxic antifouling agents to replace tin compounds.

用である。[0006] The slime layer is a slimy thin layer mainly formed by metabolites of living organisms in water.
Conventionally, thin-film slime layers have been studied to be removed as a kind of pollutant on the ship bottom. Therefore, there was no idea to actively use this to prevent the attachment of large aquatic pollutants that substantially affect the life and operation of ships such as barnacles, blue oysters, oysters, selbra, and mussels. When the inhibitor of the present invention is used, this slime layer can be positively formed on the surface of the underwater structure, thereby preventing the attachment of large aquatic fouling organisms. A method for preventing adhesion has not been known at all. The slime layer used for such a purpose has a jelly-like thickness of 0.3 mm or more, more preferably 0.5 mm to 6 mm.
mm, especially about 1 mm to 5 mm are suitable. Therefore, in the present invention, a slime layer having a thickness of about 0.3 mm or more is particularly called bio jelly. In the present invention, the thickness of the slime layer was measured on a scale after the test plate was made flat and left at room temperature for 1 hour. As described above, the slime layer or biojelly layer is mainly a metabolite of organisms in water, especially microorganisms, and is a layer in which organisms such as bacteria and diatoms can live, and those organisms are actually observed. .
Chemically, it includes various sugars, polysaccharides, lipids, glycoproteins, phospholipids, and the like. A jelly-like slime layer having a thickness of 0.3 mm or more is particularly useful for preventing the attachment of large aquatic fouling organisms.

有する化合物を特にバイオゼリー形成剤と言う。[0007] The slime layer can be positively formed on the underwater structure by applying a paint containing a certain compound. Examples of such a slime layer-forming substance include various benzylideneaniline derivatives. When these compounds are used, a thick slime layer, that is, a bio-jelly can be easily formed on the surface of the structure in water, and therefore, in the present specification, a compound having such properties is particularly used as a bio-jelly-forming agent.
