The main component of the CSC-A base material is acrylic copolymer, and the content ranges from 30% to 40%. TiO2 is used as the main white pigment, and the content ranges from 18% to 22%. The contrast ratio of the base material ranges from 0.90 to 0.96; the stormer viscosity ranges from 90 to 100KU; when the incident angle is 85 DEG, the glossiness ranges from 5 to 10. The invention has the advantages that, the composition has high weatherability and stability, and good ratio reproducibility; the adopted materials and technological process meet the environment-friendly requirements and standards of low VOC and zero VOC; compared with the standard value of the theoretical model in Chinese Color System, the real color block has very small color difference, and the accurate degree of the realization of color is high; meanwhile the manufacture technology is refined, and the practical value is extremely strong.

The invention discloses a composition of 7. 5Y 8. 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, PY153 with a dyestuff content of 40% 1. 33-1. 37 parts, P42 with a dyestuff content of 60% 1. 24-1. 28 parts, PBK7 with a dyestuff content of 9% 0.27-0.29 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.
