Embodiment 1

[0019] Weigh 0.19 grams of PY42, 2.08 grams of PG7, 0.37 grams of PBK7, and 1000 grams 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

[0020] Example 2: Weigh 0.20 grams of PY42, 2.11 grams of PG7, 0.37 grams of PBK7, and 1000 grams of CSC-A base material. Manufacturing process is with embodiment 1.

Abstract

This invention discloses a kind of 7.5BG 8 / 2 pigmentary combination and its method for preparation of color blocks. The compositions of the said combination are as follows by weight: CSC-A, the base in 995-1005 portions; PG7 with 20% color content, in 2.05-2.11 portions; PY42 with 60% color content, in 0.18-0.20 portions; PBK7 with 9% color content, in 0.36-0.38 portions. The main constituent of the said CSC-A base is acrylic acid copolymer, whose content is 30-40%. The ISO 591 R2, whose content is 18-22%, is the main used white pigment with the content of titanium dioxide greater than or equal 95%, the oil absorption less than or equal 20g / 100g and the Reynolds coefficient of the reducing power equal to 1800. The contrast ratio of the main material to the base is 0.90-0.96, the Stomer viscosity is 90-100 KU and the gloss is 5-10 degree at an incidence angle of 85 degree. The said combination in this invention has characteristics of high weather resisting property and stability, good repeatability of the mixture ratio. All of the used crude materials and technical processes meet the requirements and standards of low voice and zero voice. The chromatic aberration of the said color blocks is small compared to the standard values of the theoretic models in the book 'Chinese Color System'. With the high accuracy of the implemented color, the good proficiency of the making technique, the said product has strong use value.

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...
