Embodiment 1

[0023] Weigh 0.81 g of PBK7, 2.07 g of PG7, 1.91 g of PB15:3, and 1000 g of CSC-A 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.

Embodiment 2

[0025] Weigh 0.71 g of PBK7, 1.87 g of PG7, 1.71 g of PB15:3, and 1000 g of CSC-A base material. Manufacturing process is with embodiment 1.

Abstract

The invention discloses a 5B 7 / 4 colorant combination and a method for making physical color blocks using the colorant combination. The combination comprises by weight the following: CSC-A substrate 995 swung dash 1005 portions, PBK7, colorant content 9%, 0.71 swung dash 0.91 portions; PG7, colorant content 20%, 1.87 swung dash 2.27 portions; PB15:3, colorant content 27%, 1.71 swung dash 2.11 portions. The main component of the CSC-A substrate is a copolymer of acrylic acid that accounts for 30-40%. TiO2 is selected as the main white colorant, and the content is 18-22%. The contrast of the substrate is 0.90 swung dash 0.96, and STM viscosity is 90-100 KU. When the incident angle is 85 degree, the glossiness is 5-10 degree. The combination from the invention is of high weatherability, steadiness, and good mixture repeatability. The raw material and the process comply with the requirement and standard for environmental protection of low VOC and null VOC. The color difference of the physical color block is very low from the theoretic model in the Color System of China, the accuracy in realizing color is very high, and the producing process is concise and of very high practicability.

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...
