Abstract
The invention discloses a composition for expressing a 10RP 4 / 6 pigment and a technical method for preparing a color characterizer by using the composition. The composition consists of 995 to 1005 parts by weight of CSC-C base material; 10.2 to 10.4 parts by weight of PR254 with the pigment content of 30 percent; 0.63 part by weight of PBK7 with the pigment content of 9 percent; and 19.8 to 20.2 parts by weight of PW6 with the pigment content of 65 percent. The main ingredient of the CSC-C base material is acrylic acid copolymer, the content is 35 to 45 percent, the contrast ratio of the base material is 0.20 to 0.40, the Stormer viscosity is 90 to 100KU, and the gloss is 5 to 10 when the incident angle is 85 degrees. The color characterizer has good weatherability, stability and reproducibility of mixture ratio, and the raw materials and the process are in line with the requirements and the standards on low VOC and zero-VOC environmental protection; and compared with the standard value in a national standard theory model of the Chinese color system, the color characterizer has small color difference and high accuracy of color realization, thereby being capable of being widely applied in a plurality of fields which are 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...
