Example Embodiment

[0021] Example 1:

[0022] Weigh 11.17 grams of PY138, 19.76 grams of PW6, and 1000 grams of CSC-B base material by weight. Mix and mix the above materials, and then apply the resulting composition to the substrate evenly and evenly under the conditions of an ambient relative humidity of 50%±5% and a room temperature of 23±2°C using a mechanical coating method. It is a metallic material or a non-metallic material, the wet film thickness of the coating is 250m, and then it is placed in a precision oven at 50±2℃ to dry for 3 to 4 hours to constant weight, taken out, and cooled to room temperature to obtain a color characterization object.

Example Embodiment

[0023] Example 2:

[0024] Weigh 11.17 grams of PY138, 19.5 grams of PW6, and 1000 grams of CSC-C base material by weight. The production process is the same as in Example 1.

Example Embodiment

[0025] Example 3:

[0026] Weigh 11.17 grams of PY138, 20.0 grams of PW6, and 1005 grams of CSC-C base material by weight. The production process is the same as in Example 1.

Abstract

The invention discloses a composition expressing 10Y 9/9 pigment and a technical method for preparing a color characterization object by using the composition. The composition comprises the following components by weight portion: 995 to 1,005 portions of CSC-C base stock, 11.0 to 11.34 portions of PY138 of which the pigment content is 27 percent, and 19.5 to 20.0 portions of PW6 of which the pigment content is 65 percent. The main component of the CSC-C base stock is acrylic acid polymer of which the content is between 35 and 45 percent; the average molecular weight of the base stock is between 150,000 and 200,000, the contrast ratio of the base stock is between 0.20 and 0.40, and the Stoke viscosity of the base stock is between 90 and 100 KU; and when the incidence angle is 85 DEG, the lustrousness of the base stock is between 5 and 10. The color characterization object has good weather resistance and stability, and good matching reproduction quality, and raw materials and process used meet the environment-friendly requirement and standard of low VOC and zero VOC; and compared with the standard value of a theoretical model in national standard of Chinese color system, the color characterization object has small color difference, has high accuracy in color realization, and can be widely applied in a plurality of fields related to color.

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...
