Example Embodiment

[0022] Example 1:

[0023] Weigh 0.67 grams of PBK7, 0.14 grams of PV23, 2.07 grams of PR101, and 1000 grams of CSC-A base material by weight. Mix the above-mentioned raw materials, and then apply the mixed composition evenly and evenly on the coated paper by mechanical coating method under the environmental conditions of relative humidity of 50%±5% and room temperature of 23±2°C. The wet film thickness of the coating is 250m, then it is dried in a precision oven at 50±2°C for 3-4 hours to constant weight, taken out, cooled to room temperature, and the actual color block is obtained.

Example Embodiment

[0024] Example 2:

[0025] Weigh 0.65 grams of PBK7, 0.13 grams of PV23, 1.97 grams of PR101, and 1000 grams of CSC-A base material by weight. The production process is the same as that of Example 1.

Example Embodiment

Abstract

The invention discloses a 5RP 7.5/1 paint combination and a method of using the paint combination to prepare a real object color block. The composition of the combination by weight parts is as follows: 995-1005 parts of a CSC-A base; 0.65-0.69 parts of PBK7, with the paint content being 9%; 0.13-0.15 parts of PV23, with the paint content being 30%; and 1.97-2.17 parts of PR101, with the paint content being 65%. The CSC-A base is mainly composed of an acrylic copolymer, the content of which is 30%-40%. TiO2 is adopted as primary white paint, with the content being 18%-22%. The contrast ratio of the base is 0.90-0.96, the Stormer viscosity thereof is 90-100KU, and the glossiness thereof is 5-10 when the angle of incidence is 85 DEG. The combination has high weatherability, high stability and good proportion reproduction quality; the raw material and the process for the combination are in conformance with the low VOC and zero VOC requirements and standards for environmental protection; compared with the standard value in the theoretical model in China Color System, the chromatic aberration of the real object color block is small, the precision of color realization is very high, the manufacture process is simple, and the practical value is very high.

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...
