Description
Technical field
The present invention relates to a kind of ink for inkjet recording group, said ink group comprises cyan compsn, yellow ink compsn, magenta ink composition, green ink compsn and orange composition for ink.
Background technology
Ink-vapor recording is wherein to make the drop flight of composition for ink and be deposited on the for example printing process to print on the paper of recording medium.This method is characterised in that, can use relatively cheap equipment high speed printing high resolving power and high-quality image.
The composition for ink that is used for ink-vapor recording comprises the water as main ingredient usually, and the wetting agent that adds the tinting material component in the entry and for example be used to prevent stop up purpose glycerine for example.Water-soluble dye is for example considered their high colourity level, and their abundant available types, and their solubleness in water are widely used as the tinting material that is used for ink composition for inkjet recording so far.
On the other hand, dyestuff is for example poor on photostabilization and the water tolerance in various performances sometimes.Therefore, use the print of dyestuff-base ink compositions printing to have poor photostabilization and water tolerance.Though water tolerance improves through the ink-jet specific record paper that use contains the ink absorption layer, the water tolerance of the print on common paper has the space of improvement.
Pigment is superior to dyestuff on photostabilization and water tolerance, and considers and improve photostabilization and water tolerance, pigment is studied as the utilization that is used for the tinting material of ink composition for inkjet recording recently.Pigment is insoluble in water usually.Therefore; When pigment being used for water-base ink compositions, before the preparation of composition for ink, the following step should be provided: pigment is mixed with resin that is called dispersion agent etc.; And this mixture is added to the water, with this stabilized with mixture be dispersed in the water.
In addition; Conduct is used for the use of the tinting material of ink for inkjet recording for pigment; Pigment is superior to dyestuff on photostabilization and water tolerance, but on the other hand, the quantity of the kind of available coloured material is less than the quantity of the kind of available coloured material in the dyestuff in the pigment.When pigment is actually used in ink for inkjet recording,, also should study form and aspect satisfactorily except that photostabilization with the water tolerance.For example, Japanese Patent discloses 345080/2000 and has proposed to have the yellow ink compsn of combination that excellent sunproof specific pigment and two kinds have the specific pigment of excellent color developing a kind of comprising.In addition; Japanese Patent disclose 120956/1998 a kind of combination of cyan, magenta and the yellow ink compsn that contains specific pigment proposed the ink group; Said ink group can be implemented on photostabilization and the water tolerance, and excellent good images on form and aspect particularly.
In addition; WO1999/005230 has proposed a kind of ink group; This ink group comprises cyan compsn, magenta ink composition, yellow ink compsn and black ink composition, and the combination of other orange composition for ink and green ink compsn.The ink advantage of being claimed is, can be implemented on photostabilization and the water tolerance, and excellent good images on form and aspect particularly.
Japanese Patent discloses 283017/2006; Color developing and color reproduction scope; The color reproduction of red area particularly; Can form image through the ink group that use contains first ink and second ink enlarges; Said first ink has and is being not less than 450nm and less than the maximum absorption wavelength in the scope of 500nm; Said second ink has and is being not less than 500nm and is being not more than the maximum absorption wavelength in the scope of 570nm, and said ink group satisfies by formula B/A=and is not less than 0.7 and be not more than the requirement of 1.0 expressions, and wherein A representes that first ink and second ink are being not less than 450nm and are being not more than the maximum absorbance of the total absorbance in the wavelength region of 570nm; And B representes that first ink and second ink are being not less than 450nm and are being not more than the minimum absorbancy of the total absorbance in the wavelength region of 570nm.Above publication has also been described can form the image with good gray scale (gradation).
Summary of the invention
The inventor finds now; Method for color ink-jetting record; The ink group of combination that contains yellow ink compsn, magenta ink composition, cyan compsn, green ink compsn and the orange composition for ink of specific pigment can be implemented on photostabilization and the water tolerance; And special good images excellent on form and aspect, and need not use multiple pigment as yellow ink pigment.The present invention is based on that such discovery carries out.
