Composition for expression 10GY 4.5/9 pigment and technical method for preparing color characterization matter using thereof

Abstract

The invention discloses a composition for expressing 10GY 4.5 / 9 pigment and a technical method for preparing a color characterization object by utilizing the composition. According to weight parts, the components of the composition are as follows: CSC-C base material of 995 parts to 1005 parts; PG7 of 15.5 parts to 15.7 parts with the pigment content accounting for 20 percent; PY74 of 28.7 parts to 29.1 parts with the pigment content accounting for 40 percent; PY42 of 8.14 parts with the pigment content accounting for 60 percent. The main component of the CSC-C base materials adopts acrylic acid copolymer with the content accounting for 35 percent to 45 percent, the contrast ratio of the base materials is 0.20 to 0.40, the Stormer viscosity is 90 KU to 100 KU, and when the incident angle is 85 degrees, the glossiness is 5 to 10. The color characterization object provided by the invention has the advantages that the weatherability, the stability and the blending ratio reproducibility are good, and the adopted raw material and the technical process conform to the environmental requirements and standards of low VOC and zero VOC; compared with the standard values in the national standard theoretical model of Chinese Color System, the color differences between the color characterization object and the standard values are small, the color realization accuracy is high, and the composition which expresses 10GY 4.5 / 9 pigment and the technical method can be widely applied to various fields relating to colors.

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...
