Example Embodiment

[0021] Example 1:

[0022] Weigh 0.48 grams of PY153, 0.99 grams of PG7, and 1000 grams of CSC-A base material by weight. Mix and mix the above-mentioned raw materials uniformly, and then apply the mixed composition to the coated paper evenly and smoothly under the environmental conditions of 50%±5% relative humidity and 23±2°C at room temperature. On the top, the wet film thickness of the coating is 250μm, and then placed in a precision oven at 50±2℃ to dry for 3~4h to constant weight, take it out, and cool to room temperature to obtain the actual color block.

Example Embodiment

[0023] Example 2: Weigh 0.47 g of PY153, 0.96 g of PG7, and 1000 g of CSC-A base material by weight. The production process is the same as in Example 1.

Example Embodiment

[0024] Example 3: Weigh 0.49 g of PY153, 1.02 g of PG7, and 1005 g of CSC-A base material by weight. The production process is the same as in Example 1.

Abstract

The present invention discloses a kind of 2.5BG 9/2 pigment composition and color block made of the composition. The pigment composition consists of: CSC-A base material in 995-1005 weight portions, PY153 with pigment content 40 % in 0.47-0.49 weight portions, and PG7 with pigment content 20 % in 0.96-1.02 weight portions. The CSC-A base material contains acrylic copolymer in 30-40 % as main component; ISO 591 R2 type pigment with TiO2 content not less than 95 %, oil absorption less than 20g/100g and reducing power of 1800 as main white pigment in the content of 18-22 %; contrast ratio of 0.90-0.96, 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...
