Example Embodiment
[0021] Example 1:
[0022] Weigh 16.62 grams of PO5, 8.62 grams of PY153, and 1000 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 evenly 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 250m, and then placed in a precision oven at 50±2℃ to dry for 3-4 hours to constant weight, take it out, and cool to room temperature to obtain the actual color block.
