Zusammenfassung:	To provide a colored article and a method for producing the same.SOLUTION: The present invention relates to a colored article made of ceramics and comprises: so-called high-performance zirconia present at 80 to 99.5 wt.% based on a total weight of the ceramics; and a pigment present at 2.5 to 20 wt.% based on a total weight of the ceramic and containing one or more oxides selected from a list consisting of Al, Si, Fe, Cu, Co, Ni, Mn, Zn, Cr, Ce, V, Nd, Pr, and Ti oxides, while including mixed oxides from this list. The total percentage by weight of the high-performance zirconia, pigments and any impurities are 100%, and the ceramic has a hardness HV30 greater than 1100 HV and a toughness greater than 12 MPav√m. Also, a method for manufacturing this article is provided.SELECTED DRAWING: Figure 1 【課題】着色物品およびその製造方法を提供すること。【解決手段】本発明は、セラミックで作られ、以下を含む着色物品であって、－セラミックの総重量に基づいて８０～９９．５重量％で存在する、いわゆる高性能ジルコニア－セラミックの総重量に基づいて２．５～２０重量％で存在し、Ａｌ、Ｓｉ、Ｆｅ、Ｃｕ、Ｃｏ、Ｎｉ、Ｍｎ、Ｚｎ、Ｃｒ、Ｃｅ、Ｖ、Ｎｄ、Ｐｒ、およびＴｉ酸化物からなるリストから選択される１つまたは複数の酸化物を、このリストの混合酸化物を含め、含有する顔料、高性能ジルコニア、顔料、および任意の不純物の総重量％が１００％であり、前記セラミックが、１１００ＨＶ超の硬度ＨＶ３０および１２ＭＰａ√ｍ超の靭性を有する物品に関する。本発明はさらに、この物品の製造方法に関する。【選択図】図１
