Example Embodiment

[0022] Example 1:

[0023] Weigh 14.68 grams of PY42, 3.88 grams of PR101, 1.07 grams of PBK7, and 1,000 grams of CSC-B 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

[0024] Example 2:

[0025] Weigh 13.68 grams of PY42, 3.78 grams of PR101, 1.05 grams of PBK7, and 1,000 grams of CSC-B base material by weight. The production process is the same as in Example 1.

Abstract

The invention discloses a composition of 10YR 6. 5/2 dyestuff and process for preparing physical color lump therefrom, wherein the composition comprises (by weight portions) CSC-B base-material 995-1005 parts, P42 with a dyestuff content of 60% 13. 68-15. 68 parts, PR101 with a dyestuff content of 65% 3. 78-3. 98 parts, PBK7 with a dyestuff content of 9% 1. 05-1. 09 part. The principal ingredients of the CSC-B base-material being acrylic acid copolymer with a content of 30-40%. ISO 591 R2 type is selected as the main white dyestuff with the content = 8-12%, the content of TiO2 >=95%, oil absorption <20g/100g, tinting power = 1800, the base-material has a contrast ratio of 0.78-0.82, a Stormer viscosity of 90-100KU, when the incident angle is 85 Deg, the lustrousness is 5-10 Deg. The composition of the invention has high weatherability and stability, and good proportioning repeatability. The raw material and technical process can meet low VOC and zero VOC environmental protection requirement and standard, the obtained physical color lump has very low color-difference compared with the normalized value in theoretical models of the Chinese color systems. The invention can achieve high accuracy of color realization, fine production process and high practical values.

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...
