Zusammenfassung:	To provide a technique that enables uniform coloration onto an exposed area of a base material generated on a shape material by processing the aluminum shape material having an anodic oxide coating composite film.SOLUTION: A partial coloring method of an aluminum shape material comprises: a partial anodized aluminum treatment step in which an alumite film is formed on the surface of a base material by anodizing the exposed base material of an aluminum shape material having an anodic oxide coating composite film; and a partial coloring step in which a sealing treatment is performed by adsorbing dye on the alumite film formed on the surface of the base material.SELECTED DRAWING: None 【課題】陽極酸化塗装複合皮膜を有するアルミニウム形材の加工によって形材に生じた素地の露出箇所に、均一な着色を施すことができる技術を提供すること。【解決手段】陽極酸化塗装複合皮膜を有するアルミニウム形材に露出した素地を陽極酸化処理し、前記素地の表面にアルマイト皮膜を形成する部分アルマイト処理工程と、前記素地の表面に形成した前記アルマイト皮膜に染料を吸着させて封孔処理する部分着色工程を有する、アルミニウム形材の部分着色方法。【選択図】なし
