The present invention provides a pigment ink having carbon black having a dispersant and an ink which can provide high-grade images having a superior rub resistance without the loss of the inherent advantages of the pigment ink and can keep bleeding from occurring when color images are formed.
The ink is an ink comprising at least one salt selected from (M1)2SO4, CH3COO(M1), Ph-COO(M1), (M1)NO3, (M1)Cl, (M1)Br, (M1)I, (M1)2SO3 and (M1)2CO3 wherein M1 represents an alkali metal, ammonium or an organic ammonium, and Ph represents a phenyl group, and a carbon black having a dispersant.
本发明提供了一种具有分散剂的炭黑的颜料墨水,该墨水可以提供具有优异耐摩擦性的高级图像,而不会丧失颜料墨水的固有优点,并且可以在形成彩色图像时防止渗色。
