Embodiment 1

[0024] Weigh 16.13 grams of PY42, 3.78 grams of PR101, 11.37 grams of PBK7, 21.34 grams of PW6, and 1000 grams of CSC-C 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 250 μm, then it is dried in a precision oven at 50 ± 2 °C for 3 to 4 hours to a constant weight, taken out, and cooled to room temperature to obtain a physical color block.

Embodiment 2

[0026] Weigh 15.13 grams of PY42, 3.68 grams of PR101, 10.37 grams of PBK7, 20.34 grams of PW6, and 1000 grams of CSC-C base material by weight. The production process is the same as that of Example 1.

Embodiment 3

[0028] Weigh 17.13 grams of PY42, 3.88 grams of PR101, 12.37 grams of PBK7, 22.34 grams of PW6, and 1005 grams of CSC-C base material by weight. The production process is the same as that of Example 1.

Abstract

The N 3 pigment composition consists of CSC-C base material in 995-1005 weight portions; PY42 with pigment content of 60 % in 15.13-17.13 weight portions; PR101 with pigment content of 65 % in 3.68-3.88 weight portions; PBK7 with pigment content of 9 % in 10.37-12.37 weight portions; and PW6 with pigment content of 65 % in 20.34-22.34 weight portions. The CSC-C base material has acrylate copolymer of average molecular weight 150-200 KD as main component in content of 35-45 %. The base material has contrast ratio of 0.20-0.40, Stormer viscosity of 90-100 KU, and brightness in incident angle 85 deg of 5-10 deg. The pigment composition has high weather resistance, high stability, good compounding reproductivity and environment friendship. The color block of the composition has high accuracy and high use value.

Description

【Technical field】 [0001] The present invention relates to compositions, in particular to compositions of pigments, and physical color blocks prepared with the compositions. 【Background technique】 [0002] Colors are composed of achromatic and chromatic systems, and achromatic systems are composed of absolute white, absolute black, and gray mixed in different proportions of white and black, collectively referred to as neutral colors. The Chinese color system GB / T 15608-1995 stipulates that the symbol of neutral color is represented by N. The calibration method is to write N first, and then write the lightness grading, which is represented by N x, taking the neutral color N 5 as an example, N means that the color is a neutral color, and 5 means that the lightness of the color is 5. [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, formula and proces...
