Embodiment 1
[0023] Weigh 11.83 grams of PV23, 0.78 grams of PB15:3, 0.83 grams of PBK7, and 1000 grams of CSC-B base material. Mix the above raw materials, and then apply the mixed composition evenly and evenly on the coated paper under the environmental conditions of relative humidity of 50%±5% and room temperature of 23±2°C. The thickness of the wet film of the coating is 250m, and then placed in a precision oven at 50±2°C for 3 to 4 hours to a constant weight, then taken out, cooled to room temperature, and obtained a physical color block.

Abstract
The invention discloses a composition of a 10PB 5.5 / 7 pigment, which comprises the following components in parts by weight: 995-1005 parts of CSC-B base material, 11.65-12.01 parts of PV 23 with the pigment content of 30 percent, 0.78 part of PB15:3 with the pigment content of 27 percent and 0.8-0.86 part of PBK7 with the pigment content of 9 percent. The main component of the CSC-B base materialis acrylic copolymer the content of which is 30-40 percent and the average molecular weight range of which is 150,000-200,000. TiO2 is selected as the main white pigment and has the content of 8-12 percent. For the base material, the contrast ratio is 0.78-0.82, the Stormer viscosity is 90-100 KU, and when an incident angle is 85 degrees, the glossiness is 5-10. The composition has high weather resistance and stability and good proportioning reproducibility; the adopted raw materials and the technology process both meet the low-VOC and zero-VOC environment protection requirement and standard;and compared with a standard value in a theoretical model of Chinese Color System, the real object color block of the composition has the advantages of very little chromatism, very high accurate degree of color realization, concise manufacture process and very high practical value.
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 15608-1995 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 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 actual color block, many important links such as color dif...
