Embodiment 1

[0024] Weigh 8.41 grams of PY74, 4.2 grams of PR101, 0.49 grams of PBK7, 17.82 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 a metal material or a non-metal material. The wet film thickness of the coating is 250 μm, and then placed in a precision oven at 50 ± 2 ° C for 3 to 4 hours to a constant weight, taken out, cooled to room temperature, and obtained color characterization.

Abstract

The invention discloses a composition expressing 10YR5/4 pigments and a process for preparing a color characterization object by the same. The composition comprises the following components in parts by weight: 995-1005 parts of CSC-C base materials, 8.3-8.5 parts of PY74, 4.2 parts of PR101, 0.49 part of PBK7 and 17.6-18.0 parts of PW6, wherein the content of pigment in the PY74 is 40 percent, the content of pigment in the PR101 is 65 percent, the content of pigment in the PBK7 is 9 percent and the content of pigment in the PW6 is 65 percent. The main component of the CSC-C base materials is acrylic copolymer which has the content of 35-45 percent. The base materials have the contrast ratio of 0.20-0.40, the Stormer viscosity of 90-100KU and the glossiness of 5-10 degrees when the incident angle is 85 degrees. The color characterization object of the invention has high weather resistance and stability as well as good proportion repeatability; the used raw materials and the process accord with environment protection requirement and standard of low VOC and zero VOC; and the color characterization object has little aberration compared with the standard value in a national standard theoretical model of China Color System, and high accuracy of color implementation, and can be widely applied to fields related to the 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...
