Abstract
Images are recorded by using a magenta ink and a cyan ink including a cyan dye containing 50% by mass or more of a phthalocyanine dye represented by the following Formula (C-1) on an inkjet recording medium having at least two ink receiving layers provided on or above a substrate, wherein at least one layer of the at least two ink receiving layers comprises a basic compound, an uppermost layer that is farthest from the substrate among the at least the two ink receiving layers comprises pseudo boehmite alumina, a binder, and a water-soluble high-boiling solvent, and a lower layer provided between the uppermost layer and the substrate comprises inorganic fine particles, a binder, and at least one of a cationic polyurethane or a zirconium salt.
Claims12
An inkjet recording method, comprising:
- recording an image by an inkjet system using an ink set having a magenta ink and a cyan ink comprising a cyan dye containing 50 mass % or more of a compound represented by the following Formula (C-1) on an inkjet recording medium having at least two ink receiving layers provided on or above a substrate, wherein
- at least one layer of the at least two ink receiving layers comprises a basic compound,
- an uppermost layer that is farthest from the substrate among the at least the two ink receiving layers comprises pseudo boehmite alumina, a binder, and a water-soluble high-boiling solvent, and
- a lower layer provided between the uppermost layer and the substrate comprises inorganic fine particles, a binder, and at least one of a cationic polyurethane or a zirconium salt
- wherein, in Formula (C-1), X1, X2, X3, and X4 each independently represent —SO—Z, —SO2—Z, —SO2NV1V2, —CONV1V2, —CO2Z, —CO—Z, or a sulfo group;
- Z′s each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
- V1 and V2 may be the same or different and each represent 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 alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
- Y1, Y2, Y3, and Y4 each independently represent a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxyl group, a nitro group, an amino group, an alkylamino group, an alkoxy group, an aryloxy group, an amide group, an arylamino group, a ureido group, a sulfamoylamino group, an alkylthio group, an arylthio group, an alkoxycarbonylamino group, a sulfonamide group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, a heterocyclic oxy group, an azo group, an acyloxy group, a carbamoyloxy group, a silyloxy group, an aryloxycarbonyl group, an aryloxycarbonylamino group, an imido group, a heterocyclic thio group, a phosphoryl group, an acyl group, or an ionic hydrophilic group;
- a1 to a4 and b1 to b4 each represent the number of substituents of X1 to X4 and Y1 to Y4, respectively, provided that a1 to a4 each independently represent an integer of from 0 to 4 and are not all 0 at the same time and b1 to b4 each independently represent an integer of from 0 to 4;
- M represents a hydrogen atom, a metal atom, oxides thereof, hydroxides thereof, or halides thereof, provided that at least one of X1, X2, X3, X4, Y1, Y2, Y3, or Y4 is an ionic hydrophilic group or a group having an ionic hydrophilic group as a substituent.
