Abstract
The present invention provides a bis(2-pyridinethiol-1-oxide) copper salt coated with one or more compounds selected from glycerin, dialkyl phthalate, lubricating oil, acrylic resin, rosin, fatty acid amide, dialkyl polysulfide, polybutene, paraffin and petrolatum. The coated copper salt does not scatter, so that it is easy to handle, and is superior in safety and workability. In addition, the copper salt does not suffer from any adverse influence on the inherent storage stability or antifouling effect by being coated. Therefore, a coating for the bottom of a ship having a superior antifouling effect and storage stability can be obtained.
