Embodiment 1
[0024] In a clean anhydrous 5 liter kneader, jacket heating was started. Add 1 kg of acrylic-styrene oligomer resin, start stirring, when the temperature reaches 70 °C, make sure that all the resin has been melted, add 1 kg of red iron oxide powder for cosmetics in four times, each time adding 250 grams, stir for 20 minutes after adding, make sure the pigment is completely wetted and evenly distributed in the resin, and then add the next 250 grams of pigment. After all additions were completed, stirring was continued for 3 hours, maintaining the temperature between 90-100°C. Properly dispersed products have a clean, vibrant, high-gloss finish. Then cool the kneader through the jacket, or add 2000 grams of dry ice, cool quickly, and then use the rotating force of the kneader to crush the product. After discharging, the crushed pigment preparation was added in a pulverizer and pulverized with liquid nitrogen until the particle size was less than 75 microns. Yield 2 kg.

Embodiment 2
[0028] In a clean anhydrous 5 liter kneader, jacket heating was started. Add 1200 grams of acrylic-styrene oligomer resin, start stirring, when the temperature reaches 82°C, after confirming that all the resin has been melted and softened, add 1200 grams of FD&C yellow No. 5-aluminum salt powder in four batches , add 300 grams each time, stir for 20 minutes after adding, make sure the pigment is completely wetted and evenly distributed in the resin, and then add the next 300 grams of pigment. After all the addition, continue to stir for 3 hours, keep the temperature between 95-115 ℃, this kneading, the viscosity is higher, and the temperature is higher than the kneading temperature of other pigments. After stirring for 3 hours, cool the kneader through the jacket, or add 2000 grams of dry ice, cool quickly, and then use the rotating power of the kneader to crush the product. After discharging, the crushed pigment preparation was added in a pulverizer and pulverized with liqui...
