To provide a curable composition for production of a coating having an antimicrobial property, its use, and a method for forming an antibacterial coating on a base material.SOLUTION: A curable composition contains at least one film-forming polymer, at least one additive when necessary, at least one curing agent when necessary, and at least one up-conversion phosphor of General formula (I): A1-x-y-zB*yB2SiO4:Ln1x, Ln2z (I) (where, A is selected from Mg, Ca, Sr and Ba; B is selected from Li, Na, K, Rb and Cs; B* is selected from Li, Na and K; B is the same as or different from B*; Ln1 is selected from the group consisting of praseodymium (Pr), erbium (Er), and neodymium (Nd); and Ln2 is selected from gadolinium (Gd)). The phosphor has been prepared using at least one halogen-containing flux.SELECTED DRAWING: Figure 1.1 【課題】抗菌性を有するコーティングを製造するための硬化性組成物、その使用、基材上に抗菌コーティングを形成する方法。【解決手段】少なくとも１つのフィルム形成ポリマーと、必要に応じて少なくとも１つの添加剤と、必要に応じて少なくとも１つの硬化剤と、一般式（Ｉ）：Ａ１－ｘ－ｙ－ｚＢ*ｙＢ２ＳｉＯ４：Ｌｎ１ｘ，Ｌｎ２ｚ（Ｉ）（Ａは、Ｍｇ、Ｃａ、ＳｒおよびＢａから選択され、Ｂは、Ｌｉ、Ｎａ、Ｋ、ＲｂおよびＣｓから選択され、Ｂ*は、Ｌｉ、ＮａおよびＫから選択され、Ｂは、Ｂ*と同じか、または異なり、Ｌｎ１は、プラセオジム（Ｐｒ）、エルビウム（Ｅｒ）およびネオジム（Ｎｄ）からなる群から選択され、Ｌｎ２は、ガドリニウム（Ｇｄ）から選択される。）の少なくとも１つのアップコンバージョンリン光体と、からなり、前記リン光体は、少なくとも１つのハロゲン含有フラックスを使用して調製されたものである、硬化性組成物に関する。【選択図】図１．１
