Embodiment 1

[0023] Weigh 7.1 grams of PR254, 0.45 grams of PBK7, 22.8 grams of PW6, and 1000 grams of CSC-B base material. Mix the above materials evenly, and then apply the obtained composition on the substrate evenly and evenly by mechanical coating under the conditions of relative humidity of 50%±5% and room temperature of 23±2°C. It is metallic or non-metallic material. The wet film thickness of the coating is 250m, and then placed in a 50±2°C precision oven to dry for 3-4h to constant weight, take it out, cool to room temperature, and obtain the color characterization.

Embodiment 2

[0025] Weigh 7.21 grams of PR254, 0.45 grams of PBK7, 23.27 grams of PW6, and 1000 grams of CSC-C base material. Manufacturing process is with embodiment 1.

Embodiment 3

[0027] Weigh 7.3 grams of PR254, 0.45 grams of PBK7, 23.8 grams of PW6, and 1005 grams of CSC-C base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a composite expressing 10RP 4.5 / 6 pigment and a technological method for preparing a color characterizer by using the composite. The composite is composed of the following materials in the following weight portions: 995-1,005 portions of CSC-C base material, 7.1-7.3 portions of PR254 with pigment content of 30 percent, 0.45 portion of PBK with pigment content of 9 percent and 22.8-23.8 portions of PW6 with pigment content of 65 percent. The principal ingredient of the CSC-C base material is acrylic acid copolymer, the content of which is 35-45 percent. For the base material, the contrast ratio is 0.20-0.40, the Stormer viscosity is 90-100KU and, when the incidence angle is 85 degrees, the glossiness is 5-10. The color characterizer has good climate resistance, stability and matching reproducibility; the used raw materials and technological process conform to environment-protection requirements and standards of low VOC and zero VOC. Compared with the standard value in the national standard theoretical mode in Chinese Color System, the color characterizer has low color difference and high color implementation accuracy and can be applied to numerous color-related fields.

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...
