摘要:
Disclosed is a magenta ink composition suitable for an inkjet recording method, that has excellent print quality, has excellent fastness of the colorant on printed matter, enables inkjet recorded matter with excellent resistance to moisture, ozone, and light to be obtained, and has stable ejection reliability wherein foaming is suppressed. The magenta ink composition contains, as a colorant, at least one type of compound represented by Formula (I) below and at least one type of compound represented by Formula (II) below: [C 1]
(wherein R 1 -R 5 independently represent a hydrogen atom, an alkyl group, a sulfo group or a salt thereof; and X, Y, and Z independently represent an aromatic group or a heterocyclic group); [C 2]
(wherein M represents a hydrogen atom, ammonium group, or alkali metal atom; X represents a diaminoalkylene group; and n represents either 1 or 2).

Disclosed is a yellow ink composition suitable for inkjet recording, which has good printing quality and good colorant fixability to a recorded matter. The hue and ozone resistance of the yellow ink composition can be adjusted, while maintaining high light resistance. Also disclosed are an ink set and an ink cartridge each using the yellow ink composition, an inkjet recording method using them, and a recorded matter. Specifically disclosed is a yellow ink composition containing a compound represented by the formula (I) below and a compound represented by the formula (II) below as a colorant. [chemical formula 1] (I) (In the formula, X1, X2, Y1 and Y2 independently represent a hydrogen atom or a cyano group; Z1 and Z2 independently represent a substituent having an aromatic ring; R1 and R2 independently represent an alkyl group; and M represents a metal atom.) [chemical formula 2] (II) (In the formula, R represents a methoxy group or a methyl group; and A represents 1,5-disulfonaphtho-3-yl or 1,5,7-trisulfonaphtho-2-yl.)

Disclosed is a yellow ink composition that allows hue adjustment and ozonefastness adjustment while maintaining high lightfastness, and that has stable discharge reliability, as well as an ink set and an ink cartridge in which this composition is used, and an inkjet recording method and recorded matter in which these are used. The yellow ink composition, containing as a colorant at least one type of compound expressed by the following Formula I, and at least one type of compound expressed by the following Formula II:
(where X 1 , X 2 , Y 1 , and Y 2 are each a hydrogen atom or a cyano group, Z 1 and Z 2 are each a substituent having an aromatic ring, R 1 and R 2 are each an alkyl group, and M is a metal atom)
(where R is a methoxy group or methyl group, and A is 1,5-disulfonaphtho-3-yl or 1,5,7-trisulfonaphtho-2-yl).
摘要:
An ink composition is held in an ink container that is provided with an ink inlet through which the ink container can be refilled with the ink composition, and is used in a state in which the ink container is fitted into an inkjet recording device that includes a recording head having a nozzle hole that ejects the ink composition, the ink composition including a disperse dye, and at least one of a silicon-based surfactant and a fluorine-based surfactant, the ink composition having a surface tension of 22 to 30 mN/m.
