Composition expressing 10YR 3/1 pigment and technical method for preparing color characterization objects by using the same

The invention discloses a composition expressing 10YR 3/1 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, 18.3 to 18.9 portions of PR 101 of which the pigment content is 65 percent, 5.05 portions of PBK 7 of which the pigment content is 9 percent, and 7.1 to 7.5 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 contrast ratio of the base stock is between 0.20 and 0.40, 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.
