Example Embodiment
[0023] Example 1:
[0024] Weigh 13.38 grams of PG7, 0.01 grams of PBK7, 4.66 grams of PB15:3, 34.58 grams of PW6, and 1000 grams of CSC-B base material by weight. The above materials are mixed and uniform, and then the obtained composition is uniformly and evenly coated on the substrate by mechanical coating under the conditions of ambient relative humidity of 50% ± 5% and room temperature of 23 ± 2°C. It is a metal material or a non-metallic material, the wet film thickness of the coating is 250m, and then it is dried in a precision oven at 50±2℃ for 3-4 hours to constant weight, taken out, cooled to room temperature, and the color characterization substance is obtained.
Example Embodiment
[0025] Example 2:
[0026] Weigh 13.23 grams of PG7, 0.01 grams of PBK7, 4.66 grams of PB15:3, 34 grams of PW6, and 1000 grams of CSC-C base material by weight. The production process is the same as that of Example 1.
