Embodiment 1

[0023] Weigh 2.26 grams of PY138, 0.35 grams of PG7, 2.05 grams of PY42, and 1000 grams of CSC-A 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 combination of pigment 5GY 9 / 2 and an object color preparation method using the combination of the pigment. The combination comprises the following components by weight: 995 to 1005 proportions of base material CSC-A, 2.21 to 2.31 proportions of PY138 with 27 percent of pigment content, 0.30 to 0.40 proportion of PG7 with 20 percent of pigment content and 2.00 to 2.10 proportions of PY42 with 60 percent of pigment content. The main component of the base material CSC-A is 30 to 40 percent of acrylic copolymer; 18 to 22 percent of TiO2 is employed as main white pigment; the contrast ratio of the base material is 0.9 to 0.96, stormer viscosity is 90 to 100 KU, and when the incidence angle is 85 degrees, the glossiness is 5 to 10; the combination of the invention has good weather resistance performance, high stability and good ratio reproducibility; the employed material and technical process can meet the environment-protection requirements for low VOC content and VOC free; compared with the standard value of theoretical model in Chinese Color System, the object color has little color difference with high color realization accurate degree, proficient processing technique and high utility value.

Description

【Technical field】 [0001] The invention relates to a composition, in particular to a pigment composition, and a physical color block prepared by using 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 difference ΔE, raw materials, form...
