Embodiment 1

[0019] Weigh 78.85 grams of PY74, 10.10 grams of PY42, 21.75 grams of PO73, 25.66 grams of PW6, and 1000 grams of CSC-C base material. Mix the above raw materials, and then apply the mixed composition evenly and evenly on the coated paper 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, and then placed in a precision oven at 50±2°C for 3 to 4 hours to constant weight, taken out, cooled to room temperature, and obtained a physical color block.

Abstract

The present invention discloses a kind of 5YR 6.5/12 pigment composition and color block made of the composition. The pigment composition consists of: CSC-C base material in 995-1005 weight portions, P073 with pigment content 30 % in 21.0-22.2 weight portions, PY74 with pigment content 40 % in 77.5-80.0 weight portions, PY42 with pigment content 60 % in 10.0-10.2 weight portions, and PW6 with pigment content 65 % in 25.0-26.0 weight portions. The CSC-C base material contains acrylic copolymer in 35-45 % as main component; and has 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 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...
