Example Embodiment
[0022] Example 1:
[0023] Weigh 7.5 grams of PR101, 2.17 grams of PV23, 20.7 grams of PW6, and 1000 grams of CSC-B base material by weight. Mix the above materials uniformly, and then apply the resulting composition to the substrate evenly and evenly under the conditions of 50%±5% of ambient relative humidity and 23±2°C of room temperature by mechanical coating. It is a metallic material or a non-metallic material, the wet film thickness of the coating is 250m, then it is placed in a precision oven at 50±2℃ to dry for 3-4 hours to constant weight, taken out, and cooled to room temperature to obtain a color characterization object.
Example Embodiment
[0024] Example 2:
[0025] Weigh 7.61 grams of PR101, 2.17 grams of PV23, 21.16 grams of PW6, and 1000 grams of CSC-C base material by weight. The production process is the same as in Example 1.
Example Embodiment
[0026] Example 3:
[0027] Weigh 7.7 grams of PR101, 2.17 grams of PV23, 21.6 grams of PW6, and 1005 grams of CSC-C base material by weight. The production process is the same as in Example 1.
