摘要
合成了铜酞菁磺酰胺类衍生物,并用它们对铜酞菁颜料进行表面处理,以改进铜酞菁颜料的分散、润湿性。添加铜酞菁磺酰胺衍生物,可以提高颜料在水中的分散性,其中以脂肪链C_2～C_3的磺酰胺衍生物为好,表面处理时用量以铜酞菁量的5％为佳。经处理的铜酞菁颜料,其临界表面张力较未处理的有所下降。
A copper phthalocyanine sulphonamide derivative has been prepared and used for surface treatment of copper phthalocyanine to improve the dispersity and wettability of copper phthalocyanine pigments. It was shown that addition of copper phthalocyanine sulphonamide derivative can improve the dispersity of these pigments in water, of which the sulphonamide derivative with aliphatic C_2～C_3 chain show the best results. The amount to be used is 5％ based on that of copper phthalocyanine. The treated copper phthaloeyanine pigment have lower critical surface tensions than the copper phthaloeyanine pigment untreated.
