Structural formula:

Application performance of Reactive yellow 3RS:

1) Reactive yellow 3RS has very good light fastness, which can reach 6~7 grades under the condition of 1/1 depth. Under normal circumstances, it can meet the requirements of light fastness.

2) Reactive yellow 3RS has photochromic phenomenon:

In the application process of Reactive yellow 3RS, pay attention to the influence of external light source on the color when adjusting the color. The color becomes darker under light conditions. Therefore, in the actual production of samples, make sure that the customer's standard sample and the production sample are the same Make the judgment after balancing for a period of time under the light source. Photochromism is a reversible process, and the color light of Reactive yellow 3RS changes with the light source.

3) Reactive yellow 3RS has good solubility and levelness

The solubility at room temperature is 80g/L, so Reactive yellow 3RS dye has good level dyeing properties, and there are few color spots and spots during the production process.

The dye products produced by Milestone Industrial Co. Ltd. mainly include vat dyes, reactive dyes, sulfur dyes, acid dyes, and direct dyes; it is a dye chemical enterprise integrating industry and trade. Its products are not only sold in various regions in China, but also exported to International markets dominated by Asian and African markets.
