Embodiment 1

[0023] Weigh 0.01 g of PBK7, 1.28 g of PO73, 4.42 g of PV19, and 1000 g 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 composition of 10RP 8.5 / 4 pigments and a method for preparing a real object color hump by the same. The composition comprises the following components in parts by weight: 995-1005 parts of CSC-A base materials, 0.01 part of PBK7, 1.24-1.32 parts of PO73 and 4.36-4.48 parts of PV19, wherein the content of pigment in the PBK7 is 9 percent, the content of pigment in the PO73is 30 percent, and the content of pigment in the PV19 is 12 percent. The main component of the CSC-A base materials is acrylic copolymer, and the content of the acrylic copolymer is 30-40 percent. TiO2 is selected as main white pigment, and the content of the white pigment is 18-22 percent. The contrast ratio of the base materials is 0.90-0.96, the Stormer viscosity is 90-100KU, and the glossiness is 5-10 when the incident angle is 85 degrees. The composition has high weather resistance and stability as well as good proportion repeatability; the used raw materials and the process accord withenvironment protection requirement and standard of low VOC and zero VOC; and compared with the standard value in a theoretical model of China Color System, the real object color hump has little aberration, high accuracy of color implementation, fine manufacturing process and great practical 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...
