Abstract
Carboxylic acid ester derivatives of zosteric acid are effective in preventing biofouling and are readily formulated into coatings or films. Coating or film compositions of the esters, and methods for their application, are provided which reduce the dissolution of the esters into water or loss to the environment. The Zosteric acid esters of the invention appear to function by preventing adhesion of an organism to a surface rather than by acute toxic activity rendering said compositions more environmentally acceptable.
