Description
Technical field
The invention relates to a kind of polygenetic dye combination of tool high chroma, and the ink jet ink composition that contains this kind dye combinations.
Background technology
Generally speaking, for the requirement that color jet-ink is printd, must have broad Color Range and ideal and mix color matching, as blue or red.Ocean blue ink (cyan ink), magenta ink (magentaink), yellow ink (yellow ink) and black ink (black ink), such combination is called first step dye combinations colorant (primary dye-set).Second stage dye combinations (secondary dye-set) is meant and do not comprise first step dye combinations colorant, but other colors that form via the mixing color matching of first step dye combinations colorant.
In fact, for color jet-ink is printd, one preferable combination of inks, its ink characteristics and press quality must meet these points and require: wear-resisting (good crusting resistance), stable (goodstability), unique viscosity (proper viscosity), unique surface tension (proper surfacetension), high color saturation (high color saturation), the low dizzy property opened (little color-to-colorbleed), time of drying short (rapid dry time) etc.And when using, can on nozzle, not cause cohesion (kogation) the influence quality of prining at the ink-jet printing machine, or ink-jet is on general paper (plain paper) time, and can be as ink-jet in special quality with paper.
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
*And b
*Then represent the form and aspect (hue) and the colourity (chroma) of color.a
*Scope from represent green-a to expression red+a, b
*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 (hueangle, 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 color distortion is big more between two tinctorial patterns.
H °=tan
-1(b
*/ a
*) equation 1
So, when an ideal combination of inks is carried out ink-jet and printd image, must be able to provide best color character, for example suitable form and aspect and high chroma.
For ink-jet is printd, general known to, if only use single colorant in the ink, Chang Yi causes the obstruction (plugging) of inkjet mouth, so can add multiple wetting Agent for Printing Inks usually, but cause rate of drying slow easily, and water resisting property is poor.For example 1986, U.S.Pat.No.4,631,085,1987, U.S.Pat.No.4,731,113,1988, U.S.Pat.No.4,737,190, its ink all is that single colorant must add wetting Agent for Printing Inks to prevent aggegation.1999, U.S.Pat.No.5, in 925,177, a kind of special composition for ink comprises acid yellow dyes 23 (acidic yellow 23), urea (urea), water.The problem of adding urea can prevent yellow dyes generation crystallization and blocking ink gun.
For the color jet-ink printing machine, generally included magenta ink (magenta ink), ocean blue ink (cyan ink), yellow ink (yellow ink) and black ink (black ink), totally four chromatic inks, it is main wherein using water miscible colorant (water-base dye) mostly.Magenta ink (magenta ink) is then arranged recent years, ocean blue ink (cyan ink), yellow ink (yellow ink), black ink (blackink), shallow magenta ink (light magenta ink) and shallow foreign blue ink (light cyan ink), totally six chromatic inks, or add light yellow ink (light yellow ink), form totally seven chromatic inks.These inks, its composition comprise more than one water miscible dyestuff, water, organic solvent, and other additives.Yet, this type of water miscible dye ink, very poor on the water-repellancy of image and the light resistance after prining.
So, beginning to develop in a large number water-repellancy and the good paint ink of light resistance in recent years, it has comprised more than one pigment, water, organic solvent, and other additives.Utilize the ink for ink-jet print of pigment, on the water-repellancy and light resistance of image, than water miscible dye ink excellence for colorant.Though pigment has preferable water-repellancy and light resistance, but must cooperate suitable dispersion agent (dispersant) and adhesive agent, add pigment and have bigger particle size (particle size), so easier generation precipitation and aggegation, and the obstruction ink gun reduces the quality of prining.
