Zusammenfassung:To provide a new metal surface treatment agent, etc., capable of forming a coating film allowing the maintenance of antibacterial performance in or on the surface of a metal material.SOLUTION: A metal surface treatment agent comprises: a predetermined copolymer (A) obtained by polymerizing a compound (a) represented by the formula CH=C(R)CHN(R)(R)CHC(R)=CHX[Rand Rrepresent a hydrogen atom or a C1-4 alkyl group; Rand Rrepresent a C1-5 alkyl group; and Xrepresents a halogen atom ion or an acid anion.] and a compound (b) represented by the formula CH=C(R)CON(R)(R) or the formula CH=C(R)COOH [Rrepresents a hydrogen atom or a methyl group; Rand Rare a hydrogen atom, a C1-4 alkyl group, a benzyl group or a C2 or C3 hydroxyalkyl group; and Rrepresents a hydrogen atom or a methyl group.]; and a water soluble or water dispersible resin (B).SELECTED DRAWING: None 【課題】抗菌性能を持続することが可能な皮膜を金属材料の表面又は表面上に形成することができる新規な金属表面処理剤等を提供すること。【解決手段】式CH2=C(R1)CH2N+(R4)(R3)CH2C(R2)=CH2・X−で表される化合物(a)[R1及びR2は水素原子または炭素数1〜4のアルキル基、R3及びR4は炭素数1〜5のアルキル基、X−はハロゲン原子のイオンまたは酸アニオンを表す。]と、式CH2=C(R5)CON(R6)(R7)または式CH2=C(R8)COOHで表される化合物(b)[R5は水素原子またはメチル基、R6及びR7は水素原子、炭素数1〜4のアルキル基、ベンジル基、または炭素数2もしくは3のヒドロキシアルキル基、R8は水素原子またはメチル基を表す。]を重合することにより得られる所定の共重合物(A)と、水溶性または水分散性の樹脂(B)を含む金属表面処理剤。【選択図】なし
