Varieties characteristics Pigment Yellow 147 is excellent in thermal resistance,sublimation resistance, and light fastness. It is good compatibility with polyester, particularly suitable for the pre-coloring of spinning of polyester and polyether sulfone fibers, and can be used in automotive decorations fibers, clothes, interior textiles.

Preparation of C.I. Pigment Yellow 147 11.25 parts of 2-phenyl-4, 6-diamino-1,3, 5-triazine, 30.6 parts of 1-chloroanthraquinone and 15.9 parts of sodium carbonate were added to 200 parts of nitrobenzene, and 1.65 parts of ketone iodide was added to 9 parts of pyridine. The solution was stirred at 150-155℃ for 12h.The filtrate was filtered at 100℃ and washed with nitrobenzene at 100℃ until the filtrate showed only slight color, then washed with ethanol, and finally washed with hot water to remove free alkali. After drying, 34.7 parts of the product were obtained with a yield of 96.7%.
