In order that living thing adhesion of anti-bacterial constitution ones and the aqueous solution system which are adjusted 1 or the polymer above that and 1 or polymer - ammonium salt compound ones which have the ammonium salt above that, due to the fact that mol ratio of alkali and the chlorine (as Cl2) anti- ammonium ion mixes with approximately 1:10 or the chlorine source of approximately 10:1 is controlled the method of using this constitution ones.< Selective figure >It is not1又はそれ以上のポリマー及び1又はそれ以上のアンモニウム塩を具えるポリマー-アンモニウム塩調合物を、アルカリ及び塩素(as Cl2)対アンモニウムイオンのモル比が約1:10乃至約10:1の塩素源と混合することによって調整される抗菌構成物及び水溶液系の生物付着を制御すべくこの構成物を使用する方法。【選択図】なし
