摘要:
A method for preventing settlement of aquatic fouling organisms on surface of an aquatic structure without environmental hazard is provided. The method is based upon absolutely novel concept to prevent the settlement by means of thick slime layer, i.e. bio-jelly, deposited on said surface. The present invention also provides a bio-jelly producing agent and a bio-jelly producing paint both useful for the present method. Further, the present invention provides a novel low toxic antifouling agent.

摘要:
A method for preventing settlement of aquatic fouling organisms on surface of an aquatic structure without environmental hazard is provided. The method is based upon absolutely novel concept to prevent the settlement by means of thick slime layer, i.e. bio-jelly, deposited on said surface. The method comprises the step of applying to said surface a bio-jelly producing agent comprising a compound of the formula III: wherein X" is selected from the group consisting of hydrogen, carboxyl, hydroxymethyl, aldehyde, carbonyl and amide, when X" is carboxyl, it may be an ester or a salt thereof; Y" is selected from the group consisting of halogen, alkyl, halogenated alkyl, nitro, alkoxy, carboxyl, ester, cyano, azo, azomethine, amino, alkoxysilyl and alkoxysilylalkyl; R is selected from the group consisting of hydrogen, alkyl and halogen; q is an integer of 0-2 and p is an integer of 0 or 1.

The present invention has for its object to provide a low friction resistance coating film in water, which is capable of reducing the frictional resistance in the part of a ship or a piping where frictions with fluids such as water may take place. The present invention is directed to a low friction resistance coating film in water of which surface has a water contact angle of 0 to 40°.
摘要:
The present invention is related to a resin for use in an antifouling coating which is a polymer obtained by polymerizing a polymerizable unsaturated monomer(s) and having, at side chain terminals thereof, a trisubstituted borane-amine complex and an azomethine group, or a group represented by the following general formula (1): (wherein M represents a metal selected from the group consisting of copper, zinc, nickel and cobalt, --- means a chemically bound state, W represents -N(R 1 )R 2 - (in which R 1 and R 2 may be the same or different and each represents a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms), -OCO-, -OSO 2 - or, L represents an alkylene group containing 1 to 4 carbon atoms, and m represents an integer of 0 to 4).
