Abstract | A water-based magenta ink composition which has satisfactory storage stability, has a hue and brightness suitable for ink-jet recording, and gives prints having high fastness to light and water; and a magenta dye suitable therefor. The water-based magenta ink composition is characterized by containing as a colorant a disulfonic acid of the compound represented by formula (2) or a salt of the acid. A method of ink-jet recording with the composition is provided. The magenta dye is reduced in the contents of monosulfonic acids and inorganic metal salts, and is suitable for use in the ink composition.
L'invention concerne une composition d'encre magenta à base aqueuse présentant une stabilité au stockage satisfaisante, une teinte et une clarté appropriées pour l'impression par jet d'encre et permettant d'obtenir des impressions possédant une solidité à la lumière et à l'eau plus élevée. L'invention concerne également un colorant magenta approprié. La composition magenta à base aqueuse se caractérise par le fait qu'elle contient comme colorant un acide bisulfonique de la composition représentée par la formule (2) ou un sel de cet acide. L'invention concerne en outre un procédé d'impression par jet d'encre avec la composition. La teneur en acides monosulfoniques et en sels métalliques inorganiques est réduit dans le colorant magenta, ce qui rend son utilisation appropriée dans la composition d'encre. |
