2-Hydroxy-1,4-dimethyl-6-oxo-5-{[3-(phenylsulfonyl)phenyl]diazeny l}-1,6-dihydro-3-pyridinecarbonitrile - Reference Information
| application | disperse brilliant yellow 6GSL is suitable for dyeing polyester by high temperature and high pressure method and hot melt method, and is not suitable for dyeing by carrier method. It can be printed directly on polyester fabric, but it cannot be used as the background color for anti-pull printing. It is also used for hot melt dyeing of polyester-cotton blended fabrics. This product has good compatibility with other disperse dyes, and the color is bright yellow. It can be used as the main color or color matching in light colors. It has good dyeing performance on diacetate fiber and triacetate fiber, and it is not suitable for dyeing nylon fiber. |
| Production method | Using m-benzenesulfonate aniline and 1, 4-dimethyl-3-cyano-6-hydroxy-2-pyridine as raw materials, the former is first diazotized, and then coupled with the latter to obtain the product. The finished product is filtered, ground and dried.. |
