Abstract
A process for producing a color filter which comprises arranging a light-transmitting colored part on a surface of a base plate by applying an ink onto the base plate by an ink-jet system. The ink comprises water, an aqueous organic solvent and a coloring material, and the coloring material contains a self-dispersing pigment having at least one species of hydrophilic group bonded directly or through a linker group to a surface thereof. The color filter obtained by the process may be used in a liquid crystal panel.
Claims22
A process for producing a color filter comprising a step of arranging a light-transmitting colored part on a surface of a base plate by applying an ink onto the base plate by an ink-jet system, wherein the ink comprises water, an aqueous organic solvent and a coloring material, and the coloring material contains a self-dispersing pigment having a —COOM group bonded directly or through a linker group to a surface thereof, wherein M represents hydrogen, alkali metal, ammonium or organic ammonium.
A color filter comprising a light-transmitting colored part, wherein the light-transmitting colored part contains a self-dispersing pigment having a —COOM group bonded directly or through a linker group onto a surface of the pigment, wherein M represents hydrogen, alkali metal, ammonium or organic ammonium.
