Beschreibung
Zusammenfassung:	To provide a chemical conversion agent for forming a chemical-conversion film in or on the surface of a metal material, which has excellent appearance after chemical conversion and excellent corrosion resistance after coating as evaluated by an exposure test or VDA 621-415 and other techniques, and is able to be used in a wide temperature range.SOLUTION: A chemical conversion agent, designed for forming a chemical conversion film in or on the surface of a metal material, contains a supply source of fluorine ions, a supply source A of ions containing zirconium, a supply source B of ions containing aluminum, and a water-soluble or water-dispersible polymer containing 90% by mole or more of a structural unit represented by formula (i) or a salt C thereof.SELECTED DRAWING: None 【課題】化成後の外観及び塗装後の曝露試験やＶＤＡ６２１－４１５法等により評価される耐食性に優れ、且つ幅広い温度域で使用できる、金属材料の表面又は表面上に化成皮膜を形成する化成処理剤を提供する。【解決手段】金属材料の表面又は表面上に化成皮膜を形成する化成処理剤であって、フッ素イオンの供給源と、ジルコニウムを含有するイオンの供給源Ａと、アルミニウムを含有するイオンの供給源Ｂと、下記式（ｉ）で表される構造単位をモル換算で９０％以上含有する水溶性もしくは水分散性の高分子又はその塩Ｃと、が配合される化成処理剤である。TIFF2024084378000009.tif40170【選択図】なし
