Product introduction:
Ranbar Red SR1220-2 is a bright blue light red (rose red) water-soluble acid dye based on the structure of Xanthene, also known as anionic dye, C.I. Acid Red 52, the appearance of a red-brown powder, very high concentration, bright and shiny color, good dyeing performance, but poor sun fastness.

Ranbar Red SR1220-2 anionic dyestuff dissolved in water and ethanol solution is blue-red, and with fluorescent effect, in concentrated sulfuric acid is orange, red after dilution, aqueous solution with sodium hydroxide for blue light red.

Product Applications:
Ranbar Red SR1220-2 water-soluble dyestuff has bright color, strong dyeing power, and good leveling, but the light fastness is only 2-3 grade, and it is sensitive to water stains, so it is only suitable for the dyeing of textiles with bright color but not high requirements for color fastness, mainly used for the dyeing of wool and woolen fabrics, also used for the dyeing of silk, nylon or silk and nylon blended textiles and the dyeing of leather, paper, wood, water-based pens, etc., and also used for the dyeing of silk, nylon or silk and nylon blended textiles, It is also used for dyeing leather, paper, wood, water-based pens, etc. It can also be used for color mixing of daily chemical products and cosmetic coloring.
