The present invention provides a solution for coloring zirconia, which, when being used on pre-sintered zirconia, results in little difference in color between before and after sintering so as to enable accurate prediction of post-sintering color tone. The present invention pertains to a zirconia coloring solution which comprises: a colorant (A) that is decolorized after sintering of zirconia; and a metal ion solution (B), wherein when zirconia is dyed with said zirconia coloring solution and then subjected to sintering, the difference in color between pre-sintering and post-sintering satisfies [delta]L*<=5.8, [delta]a*<=2.4, and [delta]b*<=4.3.
本发明提供通过用于烧成前的氧化锆而减小烧成前后的色差、能够准确地预测烧成后的色调的氧化锆用着色溶液。本发明涉及氧化锆用着色溶液，其包含金属离子溶液（B）和在氧化锆的烧成后发生脱色的着色剂（A），针对使用该氧化锆用着色溶液将氧化锆着色并烧成时的烧成前后的色差，ΔL*≤5.8、Δa*≤2.4且Δb*≤4.3。
