Zusammenfassung:	A BIOCIDAL COMPOSITION IS DISCLOSED COMPRISING COMPOSITE PARTICLES, EACH OF SAID COMPOSITE PARTICLES CONTAINING A SHELL AND A CORE, SAID CORE COMPRISING A METAL OR METAL-CONTAINING COMPOUND WHEREIN THE METAL IS A MOIETY SELECTED FROM THE GROUP CONSISTING OF ZINC, COPPER, BISMUTH, SILVER, ZIRCONIUM, AND COMBINATIONS THEREOF SAID SHELL COMPRISING A PYRITHIONE ADDUCT COMPRISING THE REACTION PRODUCT OF PYRITHIONE WITH A PORTION OF SAID CORE METAL OR METAL COMPOUND. IN ONE ASPECT, AN ANTI-FOULING COMPOSITION IS DISCLOSED COMPRISING (A) AN ANTI-SOFT-FOULING EFFECTIVE AMOUNT OF COPPER PYRITHIONE; AND (B) AN ANTI-HARD-FOULING EFFECTIVE AMOUNT OF COPPER-CONTAINING SALT, OR OXIDE OR HYDROXIDE THEREOF. THE PRESENT INVENTION ALSO RELATES TO A METHOD OF MAKING AN ANTIFOULING COMPOSITION COMPRISING PARTICLES OF COPPER PYRITHIONE AND A COPPER-CONTAINING SALT THAT IS EFFECTIVE AGAINST HARD-FOULING AND SOFT-FOULING ORGANISMS.
