Embodiment 1

[0024] Weigh 6.92 grams of PG7, 0.07 grams of PBK7, 15.0 grams of PB15:3, 30.64 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 6.5 grams of PG7, 0.07 grams of PBK7, 15.5 grams of PB15:3, 29.64 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 7.5 grams of PG7, 0.07 grams of PBK7, 14.5 grams of PB15:3, 31.64 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 present invention discloses a kind of 10B 4 / 8 pigment composition and color block made of the composition. The pigment composition consists of: CSC-C base material in 995-1005 weight portions, PBK7 with pigment content 9 % in 12.0-13.5 weight portions, PB15:3 with pigment content 27 % in 4.0-4.6 weight portions, and PW6 with pigment content 65 % in 35.0-36.0 weight portions. The CSC-C base material contains acrylic copolymer with average molecular weight of 150-200 KD and in 35-45 % as main component; contrast ratio of 0.20-0.40, viscosity of 90-100 KU, and gloss index of 5-10 deg at incident angle of 85 deg. The composition of the present invention has high weather resistance, high stability, high compounding reproductivity and environment friendship. The color block is accurate and practical.

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] 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 three-dimensional, and given a certain label. The calibration method is to write the hue H first, then write the lightness V, and write the chroma C after the slash, which is represented by H V / C. Taking the color 10BG 5.5 / 6 as an example, 10BG represents the hue, 5.5 represents the lightness, and 6 represents the color. Spend. [0003] From the theoretical value in the theoretical model to the production process of the actual color block, many important l...
