Abstract
The present invention discloses a nautic blue combined colorant for ink jet printing. Said nautic blue dyes composition mainly contains acid blue dyes 90 and matches it with copper phthalocyanine blue dyes mutually. Said invented neutic blue combined colorant has good water-proofing property, can obtain excellent printing quality.
Description
Invention field
The invention relates to a kind of foreign blue combination colorant that ink-jet is printd that is applied to, and relevant for a kind of foreign blueness and color jet-ink composition for ink that contains the combination of this kind colorant.
Background of invention
For the color jet-ink printing machine, generally included magenta ink (magenta ink), foreign blue ink (cyan ink), yellow ink (yellow ink) and black ink (black ink), totally four chromatic inks.But the ink that then occurs light color series in recent years again, shallow fuchsin (light magenta), shallow ocean blue (lightcyan), light yellow (light yellow) arrange in pairs or groups in the field that ink-jet is printd, this invention also make print in ink-jet technical, horn of plenty more in the performance of color.And the most water miscible dyestuff of use of the composition of these inks (water-base dye) is main, so-called water miscible dyestuff is because of having preferable and intermiscibility water, to such an extent as to the fastness for water has just reduced greatly, and all very poor in the performance of the feasible back image water-repellancy of prining; Dyestuff is also performed poor on light resistance matter in addition, and image is faded easily, loses the keeping quality of image.Therefore, the goal of the invention of this case is to lack at this to do improvement, strengthens the water-repellancy and the light resistance of aqueous solution colorant.Case of the present invention proposes this blue colorant in ocean of associativity with preferable water-repellancy then based on the blue colorant in ocean, improves the problem of present water-soluble dye water-repellancy difference that suffers from behind the image of prining.
Whether the method for expressing of color is divided into two big colour systems according to the collection of actual look object, one is Color Appearance System (color appearance system): mainly be that collection according to actual look object gives the system that systematic arrangement and description get, Ostwald colour system for example, the Munsell colour system, German DIN colour system etc.Another is additive colo(u)r system (color mixing system): be not based on the system that actual look object is concluded, can blend the system that many colors are concluded and be based on primaries, up to the present most important additive colo(u)r system is the CIE system with the apparatus measures color.For instance, the Munsell colour system is formulated by U.S. artist Munsell, is to utilize three attributes-form and aspect (hue), lightness (value), colourity (chroma)-the describe the most famous system of color.The color stimulus of CIE system (being X, Y, Z tristimulus matter) feels it is by light source with color, object, and the merging of observer's three elements is caused, and its colour gamut is to utilize L
*, a
*, b
*This three value defines L
*The brightness (lightness of a color) of expression color, a

*Scope then from represent blueness-b to the expression xanchromatic+b.CIE system and in recommendation in 1976, added the form and aspect angle and colourity (hue angle, h °; Chroma, C
*) (equation 1 and 2).In the colour gamut of CIELAB, aberration (Δ E) is meant the color distinction degree (equation 3) between two tinctorial patterns.Δ E difference is many more, represents that the color distortion degree is big more between two tinctorial patterns.And OD (Optical density) represents optical density(OD), also can be described as absorbancy (absorbancy) its to be defined as an intensity be that the intensity that penetrates behind the rayed something of Io is I, then the value of log (Io/I) is called optical density(OD) (equation 4).

Summary of the invention
One of purpose of the present invention just provides a kind of print foreign blue dyes combination of system of ink-jet that is applicable to.
Two of purpose of the present invention just provides a kind of foreign blue ink jet ink composition with superior water-repellancy.
Three of purpose of the present invention just provides a kind of color jet-ink composition for ink that contains above-mentioned foreign blue ink.
For reaching above-mentioned purpose, foreign blue dyes combination of the present invention comprises acid blue dyes 90 (acidblue 90), and arrange in pairs or groups mutually with the blue dyes of phthalocyanine copper (copper phthalocyanine) type, this dye combinations is used in the ink for ink-jet print, because of having preferable water-resisting property (water-fastness), be applied to have when ink-jet is printd the more superior quality of prining.
The blue ink jet ink composition in ocean of the present invention is except comprising above-mentioned dye combinations colorant and an aqueous solution vehicle, still can comprise the associated additives that other is commonly used, for example organic solvent, tensio-active agent, acid-base buffer, sequestrant, sterilant, wetting Agent for Printing Inks, sanitas, uvioresistant reagent etc.
