Embodiment 1

[0022] Weigh 11.22 grams of PR122, 41.76 grams of PV19, and 1000 grams of CSC-A base material by weight. Mix the above-mentioned raw materials, and then apply the mixed composition evenly and evenly on the coated paper by mechanical coating method under the environmental conditions of relative humidity of 50%±5% and room temperature of 23±2°C. The wet film thickness of the coating is 250 μm, then it is dried in a precision oven at 50 ± 2 °C for 3 to 4 hours to a constant weight, taken out, and cooled to room temperature to obtain a physical color block.

Embodiment 2

[0024] Weigh 10.22 grams of PR122, 40.76 grams of PV19, and 1000 grams of CSC-A base material by weight. The production process is the same as that of Example 1.

Embodiment 3

[0026] Weigh 12.22 grams of PR122, 42.76 grams of PV19, and 1005 grams of CSC-A base material by weight. The production process is the same as that of Example 1.

Abstract

The invention discloses a combination of 2.5RP 7 / 11 paints and a method that uses the combination to prepare real substance color block. The combination has the components with certain weight portions: CSC-A substrate of 995-1005 portions, PR122 paint of 10.22-12.22 portions and 30 percent, and PV19 paint of 40.76-42.76 portions and 12 percent. Main component of the CSC-A substrate is acrylic copolymer with content of 30-40 percent. TiO2 is selected as the main white paint with content of 18-22 percent. The contrast ratio of the substrate is 0.90-0.96, the Stormer viscosity is 90-100KU and when the incident angle is 85 degrees, the gloss is 5-10 degrees. The combination of the invention has high weather resistance and stability, good proportion reproducibility and raw materials and technique thereof meet environmental protection requirement and standard of low VOC and no VOC; the real substance color block has little color difference from the standard value specified in theoretical mold in the Chinese Color System, has high accuracy of real color, delicate manufacturing technique and high practical value.

Description

【Technical field】 [0001] The present invention relates to compositions, in particular to compositions of pigments, and physical color blocks prepared with the compositions. 【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 three-dimensional, and given a certain label. The calibration method is to write the hue H first, then write the lightness V, and write the chroma C after the slash, which is represented by H V / C. Taking the color 10BG 5.5 / 6 as an example, 10BG represents the hue, 5.5 represents the lightness, and 6 represents the color. Spend. [0003] From the theoretical value in the theoretical model to the production process of the actual color block, many important l...
