Example Embodiment
[0022] Example 1:
[0023] Weigh 14.68 grams of PY42, 3.88 grams of PR101, 1.07 grams of PBK7, and 1,000 grams of CSC-B base material by weight. Mix and mix the above-mentioned raw materials uniformly, and then apply the mixed composition to the coated paper evenly and smoothly under the environmental conditions of 50%±5% relative humidity and 23±2°C at room temperature. On the top, the wet film thickness of the coating is 250μm, and then placed in a precision oven at 50±2℃ to dry for 3~4h to constant weight, take it out, and cool to room temperature to obtain the actual color block.
