Embodiment 1
[0024] Weigh 0.68 grams of PG7, 0.49 grams of PBK7, 2.41 grams of PY42, 49.06 grams of PW6, and 1000 grams of CSC-B base material. Mix the above materials evenly, and then apply the obtained composition on the substrate evenly and evenly by mechanical coating under the conditions of relative humidity of 50%±5% and room temperature of 23±2°C. It is metallic or non-metallic material. The wet film thickness of the coating is 250m, and then placed in a 50±2°C precision oven to dry for 3-4h to constant weight, take it out, cool to room temperature, and obtain the color characterization.

Abstract
The invention discloses a composition expressing the 10GY 6.5 / 1 pigment and a technical method for preparing a color token with the composition. The composition is composed of the following portions by weight: 995-1005 portions of CSC-C base material; 0.68 portion of PG7 with 20 percent of pigment content; 0.49 portion of PBK7 with 9 percent of pigment content; 2.35-2.45 portions of PY42 with 60 percent of pigment content; 48-50 portions of PW6 with 65 percent of pigment content. The main component of the CSC-C base material is acrylic acid copolymer with a content of 35-45 percent; the contrast ratio of the base material is 0.20-0.40; the Stormer viscosity thereof is 90-100 KU; when the incident angle is 85 degrees, the lustrousness thereof is 5-10. The color token of the invention has good weather resistance and stability; the proportioning reproducibility is excellent; the raw material and technological process are in accordance with the environmental protection requirement and standard for low VOC and zero VOC; the color token has little color discrepancy with the standard value set by the national standard theoretical model of Chinese color system; the accurate degree for realizing color is high; and the color token can be widely applied in a plurality of fields relevant to color.
Description
【Technical field】 [0001] The present invention relates to a composition, in particular to a composition of pigments, and a technical method for preparing color representations from 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 on the color plane, and given a certain label. The calibration method is to first write the hue H, then write the lightness V, write the chroma C after the slash, expressed as H V / C, take the color 10BG 5.5 / 6 as an example, 10BG means the hue, 5.5 means the lightness, and 6 means the color Spend. [0003] From the theoretical value in the theoretical model to the production process of the color representation, many important links such as color differ...
