Embodiment 1
[0023] Weigh 1.14 grams of PBK7, 1.82 grams of PG7, 10.1 grams of PB15:3, 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.
Embodiment 2
[0025] Weigh 1.14 grams of PBK7, 1.75 grams of PG7, 10.1 grams of PB15:3, and 1000 grams of CSC-B base material by weight. The production process is the same as that of Example 1.
Embodiment 3
[0027] Weigh 1.14 grams of PBK7, 1.82 grams of PG7, 10 grams of PB15:3, and 1005 grams of CSC-B base material by weight. The production process is the same as that of Example 1.

Abstract
The invention discloses a composition of 7.5B 5.5 / 7 pigment. The composition comprises the following components in weight portion: 995 to 1,005 portions of CSC-B base stock, 10 to 10.2 portions of PB15:3 the pigment content of which is 27 percent, 1.14 portions of PBK7 the pigment content of which is 9 percent amd 1.75 to 1.9 portions of PG7 the pigment content of which is 20 percent. The main component of the CSC-B base stock is acrylic acid polymer the content of which is between 30 and 40 percent; the range of the average molecular weight of the base stock is between 150,000 and 200,000; TiO2 is selected as the main white pigment the content of which is between 8 and 12 percent; the contrast ratio of the base stock is between 0.78 and 0.82, the Stoke viscosity of the base stock is between 90 and 100 KU; when the incidence angle is 85 DEG, the lustrousness of the base stock is between 5 and 10. The color characterization object of the invention has good weather resistance, high 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, 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 compositions, particularly pigment compositions, and techniques for preparing color characterizations using such compositions. 【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 15608-1995 stipulates that in the theoretical model of the Chinese color system, any color can be calibrated by the hue, lightness and chroma on the color three-dimensional, and given a certain label. The calibration method is to write the hue H first, then write the lightness V, and write the chroma C after the slash, which is represented by H V / C. Taking the color 10BG 5.5 / 6 as an example, 10BG represents the hue, 5.5 represents the lightness, and 6 represents the color. Spend. [0003] From the theoretical value in the theoretical model to the production process of the color characterization, ...
