Abstract
An anti-fouling paint using self-polishing copolymer which contains n-[(N-isothiazolonyl)-alkyl] acrylate as one of the monomers has improved anti-fouling property and can reduce environmental hazard by reduction of the leaching amount of biocide like organotin and of additional biocide like copper compound. The paint can control the rate of dissolution and prolong the effectiveness of the paint.
