Abstract
Official abstract text for this publication.
A rigid decorative member of the present invention is a rigid decorative member comprising a base and a rigid coating layer laminated on or above the base, wherein the rigid coating layer comprises a reaction compound of raw metal, in which a metal M 1 and a metal M 2 , and in addition, selectively a metal M 3 are combined, and of a non-metallic element selected from one or two or more of nitrogen, carbon, and oxygen, or comprises an alloy in which a metal M 1 and a metal M 2 , and in addition, selectively a metal M 3 are combined; the metal M 1 is selected from one or two of Mo and W; the metal M 2 is selected from one or two or more of Nb, Ta, and V; and the metal M 3 is selected from one or two or more of Cr, Ti, Hf, and Zr.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rigid decorative member comprising a base and a rigid coating layer laminated on or above the base, wherein the rigid coating layer comprises a reaction compound of (i) raw metal, in which a metal M 1 and a metal M 2 and optionally a metal M 3 are combined, and (ii) a non-metallic element selected from one or two of nitrogen and carbon, or comprises an alloy in which a metal M 1 and a metal M 2 and optionally a metal M 3 are combined; the metal M 1 is selected from one or two of Mo and W; the metal M 2 is selected from one or two of Nb and Ta; and the metal M 3 is selected from one or two or more of Cr, Ti, Hf, and Zr. 2. The rigid decorative member according to claim 1 , wherein the raw metal is a raw metal in which the metal M 1 and the metal M 2 are combined with the metal M 3 ; and the metal M 3 is Cr. 3. The rigid decorative member according to claim 1 , wherein 70 mass % or more in total of the metal M 1 and the metal M 2 is contained in the raw metal. 4. The rigid decorative member according to claim 1 , wherein the rigid coating layer has a thickness of 0.5 to 4μm. 5. The rigid decorative member according to claim 1 , wherein the appearance color of the rigid coating layer is a white color or a stainless steel color. 6. The rigid decorative member according to claim 1 , wherein an undercoat layer is further laminated between the base and the rigid coating layer, or a finishing layer is further laminated on or above the rigid coating layer. 7. A watch comprising an exterior part, wherein a portion or the entirety of the exterior part comprises the rigid decorative member according to claim 1 . 8. A method for producing a rigid decorative member, comprising laminating a rigid coating layer on or above a base, wherein the rigid coating layer comprises a reaction compound of (i) raw metal, in which a metal M 1 and a metal M 2 and optionally a metal M 3 are combined, and (ii) a non-metallic element selected from one or two of nitrogen and carbon, or comprises an alloy in which a metal M 1 and a metal M 2 and optionally a metal M 3 are combined; the metal M 1 is selected from one or two of Mo and W; the metal M 2 is selected from one or two of Nb and Ta; and the metal M 3 is selected from one or two or more of Cr, Ti, Hf, and Zr. 9. The method for producing a rigid decorative member according to claim 8 , wherein the raw metal is an alloy in which a metal M 1 and a metal M 2 and optionally a metal M 3 are combined; and the rigid coating layer is laminated on or above the base by a reactive sputtering method.
