摘要:
An object of the present invention is to provide an ink composition which, when used with an ink jet recording apparatus, can realize excellent ink ejection stability while maintaining safety and satisfactory penetration of ink. The ink composition according to the present invention comprises at least a pigment, a dispersant for dispersing the pigment, a 1,2-alkanediol, and water as a main solvent, the content of the 1,2-alkanediol being 0.5 to 10% by weight based on the total amount of the ink composition.
摘要:
An ink set comprising water-based pigment inks of at least six different colors, namely of black, cyan, magenta, yellow, light cyan, and light magenta, characterized in that:
each of said water-based pigment inks of said six different colors contains a pigment as a colorant and a solvent; at least said water-based inks of light cyan color and light magenta color each contains an emulsion having fine polymer particles as dispersoid; and said emulsions exhibit minimum film producing temperatures of 25°C or lower.
摘要:
An aqueous ink composition comprising at least water, a pigment dispersed by polymer, a sulfonyl group-containing (co)polymer, and an ultra-penetrating agent. Also disclosed are a recording process using the ink composition, an ink cartridge containing the ink composition, and a recorded article having an image recorded by the recorded method.
