[0089] The chromaticity performance of the novel ceramic colorant samples prepared in Examples 1-6 and Comparative Examples 1-2 was tested, as shown in Table 1.

[0090] Table 1 Chromaticity properties of different new ceramic colorant samples

[0091] project L a b Example 1 39.5 42.8 27.5 Example 2 40.2 41.6 28.3 Example 3 38.6 40.5 27.9 Example 4 40.9 43.1 28.1 Comparative Example 1 32.1 36.9 25.6 Comparative Example 2 35.3 37.8 23.2

[0092] As can be seen from Table 1, the new ceramic colorant of the present invention has better color rendering ability and pure color due to the addition of photosensitive resin.

In the high-temperature solid-phase synthesis temperature specified in the present invention of 1200-1450°C, Example 1 is the optimum temperature, and the color rendering ability is the best. There is a large gap between Example 3 and Example 4 compared with the optimum temperature, and the color rendering effect is significantly reduced. In Comparative Example 2, the bio-oil phenolic epoxy photosensitive resin is replaced with trimethylolpropane methylal acrylate, and the color rendering ability is greatly reduced, which seriously affects the color rendering ability and other performances.

[0093] The use of bio-oil phenolic epoxy photosensitive resin also has a great influence on the color rendering ability of ceramic colorants. From the values ​​in Table 1, it can be seen that the use of zirconium silver red as a colorant and the addition of bio-oil phenolic epoxy hybrid photosensitive resin can make the performance of the ceramic colorant more stable, the surface of the fired ceramic products is bright, soft and flat, and the decorative effect of the ceramic products will never change color.
