Beschreibung
Zusammenfassung:	To provide a surface treatment agent which enables formation of a film that is excellent in durability (corrosion resistance and coated film adhesion) of not only a flat part but also a processing part of a material.SOLUTION: A surface treatment agent contains an aqueous epoxy resin (A), block isocyanate (B), and water, in which the aqueous epoxy resin (A) has a structure polymerized with one or a plurality of kinds of vinyl monomers, the one or plurality of kinds of vinyl monomers contain a vinyl monomer having a carboxyl group, and the block isocyanate (B) has an isocyanate group blocked with a blocking agent, an isocyanurate structure and a polyalkyleneoxy chain.SELECTED DRAWING: None 【課題】材料の平面部のみならず加工部の耐久性（耐食性及び塗膜密着性）に優れる皮膜を形成可能な表面処理剤を提供する。【解決手段】水性エポキシ樹脂（Ａ）と、ブロックイソシアネート（Ｂ）と、水とを含有する表面処理剤であって、前記水性エポキシ樹脂（Ａ）は、１又は複数種のビニルモノマーが重合した構造を有し、前記１又は複数種のビニルモノマーは、カルボキシル基を有するビニルモノマーを含み、前記ブロックイソシアネート（Ｂ）は、ブロック剤によりブロックされたイソシアネート基、イソシアヌレート構造及びポリアルキレンオキシ鎖を有する、表面処理剤。【選択図】なし
