ANTIBACTERIAL AGENT, ANTIBACTERIAL MEMBER, AND USE METHOD

To provide an antibacterial agent which exhibits excellent antibacterial property at a small amount even being blended in a resin or the like, and which is a light responsive type, and an antibacterial member acquired from the antibacterial agent, and a use method as an antibacterial agent.SOLUTION: There is provided an antibacterial agent including, as an active ingredient, a compound comprising in a molecule, peroxide bond and a thioxanthone skeleton, and being expressed by a general formula (1). There is also provided an antibacterial member obtained by applying on a substrate, the antibacterial agent, and drying and/or curing the substrate. There is also provided a use method of the compound comprising in a molecule, peroxide bond and a thioxanthone skeleton, as the antibacterial agent. (In the formula (1), R1, R2, R3 and R4 independently express a methyl group or an ethyl group, R5 is an alkyl group having C1-C6 or a phenyl group, R6 is an independent substituent group and expresses an alkyl group having C1-C4, an alkoxy group having C1-C4, or a chlorine atom and n is an integer from 0 to 2.)SELECTED DRAWING: None 【課題】樹脂等に配合した場合においても、少量で抗菌性に優れる、光応答型の抗菌剤を提供する。また、前記抗菌剤から得られる抗菌性部材、及び抗菌剤としての使用方法を提供する。【解決手段】下記一般式（１）で表される、分子内に過酸化結合とチオキサントン骨格を有する化合物を有効成分とする抗菌剤。基材上に前記抗菌剤を塗布し、乾燥及び／又は硬化させてなる抗菌性部材。分子内に過酸化結合とチオキサントン骨格を有する化合物の抗菌剤としての使用方法。JPEG2022042112000007.jpg23129（式（１）中、Ｒ１、Ｒ２、Ｒ３およびＲ４は独立してメチル基またはエチル基を表し、Ｒ５は炭素数１～６のアルキル基、またはフェニル基を表し、Ｒ６は独立した置換基であって、炭素数１～４のアルキル基、炭素数１～４のアルコキシ基、または塩素原子を表し、ｎは０から２の整数を表す。）【選択図】なし
