What are yellow pigments for color pastes and red pigments for color pastes?

Color paste is made by mixing and grinding pigments and other solvents in a proportion. It is a semi-finished product of paint or coating. Compared with toner, it is easier to use, less expensive, and has no dust pollution. characteristics, so it has a great dyeing position in the market. Since toner can be used in both coatings and inks, color pastes are also divided into color pastes for coatings and paints and color pastes for inks. According to different System, color paste is divided into oily color paste and water-based color paste, so the pigments used in color paste are also different.

First of all, pigments for color pastes are divided into inorganic pigments and organic pigments. The difference between inorganic pigments and organic pigments will not be repeated here. The color paste uses yellow pigment, and the basic colors are divided into three types: medium yellow, golden yellow and lemon yellow. Medium yellow can be divided into inorganic pigment iron oxide yellow and organic pigment 3140 permanent yellow 2GS and 3550 permanent yellow 2RN, one green phase and one yellow phase. Most golden colors on the market use permanent yellow HR, that is, 83# yellow Commonly used tartrazine pigments on the market include 3030 lightfast yellow and 3810 benzidine yellow 10G. Among them, benzidine yellow 10G is widely used in the market due to its lightfastness and migration resistance.

The color paste uses red pigment, which has a relatively large and complete chromatogram and many application areas. The basic colors are divided into six categories: bright red, purple red, bright red, magenta, deep purple red, peach, and pink. In the inorganic pigment system, iron oxide red is also a type of red pigment used in color pastes. Among paint pastes, due to the non-migrating characteristics of most paints, the bright red pigment is generally Pigment Red BBS or Permanent Red F3RK, the purple color is Lightfast Red BBC, the bright red color is Permanent Red F5RK, and the magenta color is Pigment red 57:1, peach pink pigment is 122# red, and deep purple color is lightfast purple red 2R. The above colors are commonly used pigments in general color pastes. For coatings or inks with very specific requirements, the color pastes are High-performance pigments should be used as red pigments.

Other color pastes use blue pigments and green pigments, most of which are commonly used phthalocyanine blue pigments and phthalocyanine green G. Huake Brothers made a simple arrangement of color paste pigments, as shown in the picture:
