Zinc pyrithione and copper pyrithione are highly appreciated in the market as a dandruff preventive for shampoo, or an antifouling agent for ship bottom paint and fishing net, or an antibacterial antifungal agent or antiseptic antimordant agent for industrial products and home goods. For enhancing the market value thereof, there has been a demand for a product that not only attains an increase from conventional antibacterial antifungal effects but also exhibits novel bioactive effects and that achieves improvement with respect to problems and drawbacks relating to properties, such as solubility in seawater, and stability, such as thermal stability and weather resistance, of polymer materials. There is provided a novel pyrithione complex compound obtained by converting the conventional pyrithione metal salt to a complex compound with an oxide or hydroxide of metal such as zinc, copper or aluminum. As compared with the conventional pyrithione metal salt, this complex compound exhibits superior antibacterial antifungal effects, newly realizes a hair growing effect and successfully attains improvement with respect to the solubility in seawater and thermal stability/weather resistance of polymer materials. ® KIPO & WIPO 2007
