Inkjet recording ink and inkjet recording method

1. An inkjet recording method comprising:

preparing an image-receiving material which comprises a support and an image-receiving layer comprising white inorganic pigment particles; and

ejecting an ink droplet comprising an ink to the image-receiving material according to recording signals so as to record an image on the image-receiving material,

said ink comprising an aqueous medium and at least one dye represented by the following formula (II) which is dissolved in the aqueous medium, wherein the ink permeates into a recording medium having an image-receiving layer to a depth of 5 to 30 μm:

wherein X 11 , X 12 , X 13 , and X 14 each independently represents —SO-Z, —SO 2 -Z, —SO 2 NR 1 R 2 , or —CONR 1 R 2 , each Z independently represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group, R 1 and R 2 each independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group, Y 11 to Y 18 each independently represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cyano group, an alkoxy group, an amido group, a ureido group, a sulfonamido group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, a carboxyl group or a sulfo group, M represents a hydrogen atom, a metal atom or an oxide, hydroxide or halide thereof, and a 11 to a 14 each independently represents an integer of 1 or 2, provided that when at least one of a 11 to a 14 each represents a number of 2, corresponding plurality of substituents X 11 , X 12 , X 13 or X 14 may be the same or different, and

wherein an amount of the dye represented by the formula (II) is from 0.2 to 20% by weight.

2. The inkjet recording method according to claim 1 , wherein the amount of dye represented by formula (II) is from 0.5 to 15% by weight.

3. The inkjet recording method according to claim 1 , wherein the phthalocyanine dye represented by the formula (II) has at least two ionic hydrophilic groups within one molecule of the phthalocyanine dye.

4. The inkjet recording method according to claim 1 , wherein the ink contains 0.1 to 10% by weight of a surfactant.

5. The inkjet recording method according to claim 1 , wherein the ink contains 1 to 60% by weight of a water-miscible organic solvent.

6. The inkjet recording method according to claim 1 , wherein that the ink has surface tension of from 20 to 50 mN/m.

7. The inkjet recording method according to claim 1 , wherein that the ink has viscosity of 30 mPa·s or less.
