Embodiment 1
[0023] Weigh 8.3 grams of PG7, 21.61 grams of PY42, 22.72 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.
Embodiment 2
[0025] Weigh 8.3 grams of PG7, 21.4 grams of PY42, 22.72 grams of PW6, and 1000 grams of CSC-C base material by weight. The production process is the same as in Example 1.

Abstract
The invention discloses a composition expressing 10GY 5.25 / 5 pigment and a technical method for preparing a color characterization object by using the composition. The composition comprises the following components in weight portion: 995 to 1,005 portions of CSC-C base stock, 8.3 portions of PG7 the pigment content of which is 20 percent, 21.4 to 21.8 portions of PY42 the pigment content of which is 60 percent, and 22.5 to 22.9 portions of PW6 the pigment content of which is 65 percent. The main component of the CSC-C base stock is acrylic acid polymer the content of which is between 35 and 45 percent; the contrast ratio of the base stock is between 0.20 and 0.40, the Stoke viscosity of the base stock is between 90 and 100 KU; and when the incidence angle is 85 DEG, the lustrousness of the base stock is between 5 and 10. The color characterization object has good weather resistance and stability, and good matching reproduction quality, and raw materials and process used meet the environment-friendly requirement and standard of low VOC and zero VOC; compared with the standard value of a theoretical model in national standard of Chinese color system, the color characterization object has small color difference, has high accuracy in color realization, and can be widely applied in a plurality of fields related to color.
Description
【Technical Field】 [0001] The present invention relates to a composition, in particular to a composition of a pigment, and a technical method for preparing a color characterization object using the composition. 【Background technique】 [0002] A color includes hue, lightness and chroma. As long as the hue, lightness and chroma are determined, a unique color can be determined. The Chinese color system GB / T 15608 stipulates that in the theoretical model of the Chinese color system, any color can be calibrated by the hue, lightness and chroma of the three-dimensional color, and given a certain label. The calibration method is to write the hue H first, then the lightness V, and the chroma C after the slash. Use HV / C as an example. Take the color 10BG 5.5 / 6 as an example. 10BG represents hue, 5.5 represents lightness, and 6 represents color. degree. [0003] From the theoretical value in the theoretical model to the production process of the color representation, many important links su...
