Example Embodiment

[0021] Example 1:

[0022] Weigh 3.24 grams of PBK7, 27.69 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 method. It is a metallic material or a non-metallic material, the wet film thickness of the coating is 250m, and then it is placed in a precision oven at 50±2℃ to dry for 3 to 4 hours to constant weight, taken out, and cooled to room temperature to obtain a color characterization object.

Abstract

The invention discloses a combination of 10PB 4/1 dye and a technical method for using the combination to prepare a color characterization matter. The combination consists of the components with the weight portions as follows: 995 to 1005 portions of CSC-C base; 3.2 to 3.3 portions of PBK7 with a dye content of 9 percent as well as 27.4 to 30 portions of PW6 with a dye content of 65 percent. The main component of the CSC-C base is an acrylic copolymer; the content is 35 to 45 percent; the average molecular weight is 0.15 to 0.2 million; the contrast ratio of the base is 0.20 to 0.40; the Stormer viscosity is 90 to 100KU; when the incident angle is 85, the lustrousness is 5 to 10. The color characterization matter has excellent weatherability and stability as well as good ratio reproducibility; the materials and the technical flow accord with the demands and standards for environment protection of low VOC and zero VOC; compared with the standard value of the national standard theoretical mode in Chinese Color System, the color difference of the color characterization matter is small; the accurate degree for realizing color is high; the color characterization matter can be broadly applied in a plurality of fields relative 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...
