COMPOSITION DE MATÉRIAU DE REVÊTEMENT ANTISALISSURE, FILM DE REVÊTEMENT ANTISALISSURE, BASE ANTISALISSURE ET SON PROCÉDÉ DE PRODUCTION, ET PROCÉDÉ DE STOCKAGE DE LA COMPOSITION DE MATÉRIAU DE REVÊTEMENT ANTISALISSURE
[Object]To provide an antifouling coating composition which contains a silyl ester (co) polymer and medetomidine and is used to prevent the fouling of substrates by aquatic organisms and which can form antifouling coating films exhibiting outstanding antifouling properties over a long period and also has good storage stability, and to provide use applications of the composition.[Solution]The antifouling coating composition includes a silyl ester (co)polymer (A) and medetomidine (B), the silyl ester (co)polymer (A) including structural units derived from a monomer (a) represented by the general formula (I): R1-CH=C(CH3)-COO-(SiR2R3O)n-SiR4R5R6, and structural units derived from an unsaturated monomer (b) copolymerizable with the monomer (a).
