Abstract

An ink/media combination in which the ink comprises an aqueous medium, a colorant and an alginic acid salt selected from the group consisting of monovalent ion salts and organic amine salts and in which the media, preferably a textile, is treated with a specified water soluble salt of a metal having a valence of at least 2 produce printed chromatic image with improved bleed characteristics and sharper edges.

Description

Ink/media combination
The present invention relates to a kind of printing ink that in ink jet printing, uses and media combination, particularly produce the ink/media combination of colored and sharp-edged image.
The method that many production printed elements are arranged wherein imposes on printed liquid on the matrix to form image.Well known in the art, term " printed liquid " refers to be different from the tinting material in liquid medium of solid and dry colorant, comprises coating, toning agent, printing ink etc.Liquid medium can be organic solvent (" solvent base ") or water (" water base ").Tinting material can be dyestuff or pigment.General other component that exists in printed liquid depends on employed special printing technology.
Use the typical method of printed liquid to comprise photoengraving, the impression printing, the xeroprinting technology of use liquid toner, and ink jet printing, or the like.In these methods, can produce the polychrome printing product owing on matrix, once scan introducing three or four primaries printing ink, it is more and more universal that ink jet printing becomes, and uses especially for so-called " publication table (desk-stop publishing) ".Every kind of primary colors of printing process for other generally needs at least by printing press once.
Although be applicable to that the technical scope of producing printed element is wide, when wishing to obtain the polychrome element, produced a common problem, wherein a kind of printed liquid of color is placed on the printed liquid of other color of adjoining.Show at the interface of two kinds of printed liquid and mix or " bleeding " this problem, therefore the blur boundary between two kinds of printed liquid is unclear.Bleeding can form at the interface not to be wished the color that obtains and causes that in image resolving power, color separation, edge acuity and colour purity reduce simultaneously.The color of two kinds of liquid that adjoin (as black and yellow) contrast is big more, and the visible bleeding is serious more.(as when blueness and yellow are mixed the generation green) bleeding also is significant especially when two kinds of printing ink mix the generation secondary color.
Bleeding is the specific question in the ink jet printing, prints three or four primaries because employed low viscous relatively printing ink helps to spread with the ink jet printing function in (or near simultaneously) mode simultaneously.
People have recommended to prevent the several method of the printed liquid bleeding of adjoining.The most significant method is alternately to apply at interval two kinds of printed liquid, so that the mixing of two kinds of printed liquid does not take place and mixes up.But this method is not a method of dealing with problems, and the image resolution rate variance that produces.
The most normally used a kind of other method comprises up to first kind of printed liquid complete drying and just postpones to apply second kind of printed liquid.The shortcoming of this method is because not only its efficient is low but also do not have a special effect.For example, be that exsiccant also bleeding may take place even people observe first kind of printed liquid, it is believed that this is because the tinting material of first kind of printed liquid " dissolving again " is caused in the liquid medium of second kind of printed liquid.Therefore, even first kind of printed liquid is exsiccant, the component of first kind of printed liquid is easy more to be dissolved in the liquid medium, more bleeding may take place.This method significant disadvantage in ink jet printing is used is because it produces uncertain border at printed matter.
U.S. Pat 5091005 instructions add the generation that methane amide can reduce bleeding in some cases in printing ink.The method that also has another kind of control bleeding is to improve the seepage velocity that printed liquid enters matrix, but it has the shortcoming of himself.At first, it is confined in those printings of using special printed liquid/matrix binding substances application substantially.For example, need high absorption base control bleeding.The second, make it on the matrix not by the dissolving of the liquid medium of second printed liquid unless first printed liquid is attached to, otherwise bleeding still can occur.The 3rd, the known method that increases infiltration has the shortcoming that reduces the version quality.
U.S. Pat 5116409 discloses the combination of aforesaid method, discloses working concentration and has surpassed the zwitterionics or the non-ionic amphiphilic thing of corresponding micelle-forming concentration separately.It is generally acknowledged that the micellar that contains dye molecule forms can prevent in the various printing ink that dye molecule mixes.
The method of a kind of ink jet printing of U.S. Pat 5181045 instruction, wherein a kind of printing ink contain to become under certain PH condition and are difficult to dissolved dyestuff and another kind of printing ink and have and give the contained dyestuff of first printing ink insoluble pH value.But this method is subjected to limit as the intrinsic of the specific groups of the dyestuff of tinting material.In addition, this ink formulations is owing to need the PH buffer reagent also to be restricted, and for example, it has further limited the purposes of this method.
EP 0586079A1 discloses the method that is used to prevent the color bleeding between two kinds of different colours ink composites, and wherein first kind of printing ink is anionic and comprises a kind of tinting material that this tinting material contains one or more carboxyls and/or carboxylate groups; Contain precipitation agent with second kind of printing ink, this precipitation agent be used for first printing ink in tinting material carry out ionization and be cross-linked to form solid precipitation, to prevent bleeding between two kinds of ink composites.The polyvalent metal salt that uses as precipitation agent is also disclosed.Though this method provides effective bleeding control for two kinds of printing ink, when imposing on printed medium with two or more printing ink, this is a difficult problem in production polychrome printing product.In addition, this method do not allow in first printing ink and to select tinting material to be restricted flexibly owing to it, first kind of printing ink must have can with one or more carboxyls of precipitation agent ionization bonded and/or the carboxylate groups in second kind of printing ink.
Dyestuff is because the solubility of dyestuff in water as normally used tinting material in ink jet printing.In addition, dyestuff provides great-hearted colour on printing paper.But what lose sense is that many dyestuffs have bad photostabilization, water tolerance and anti-keeping property on paper.Therefore, the dye coloring agent is defective for the printing sample of filing preservation.
Usually have good photostabilization, water-proof pigment colorant and can be used as the alternative of dyestuff.But many pigment can not reach the tinctorial strength (i.e. " colourity ") same with dyestuff on printing paper.
A kind of method of improving face material colourity is to use a kind of vehicle (vehicle), this vehicle fixedly tinting material and do not allow pigment to diffuse into printed medium, for example fabric and paper on the paper surface.But this vehicle often can not penetrate medium and not be suitable for rapid drying or bleeding control.
Therefore, need a kind of improved method that is used to print the multicolor image that does not produce aforementioned bleeding problem.In addition, need such improving one's methods especially, this method goes up at medium (as fabric, common paper or the like) can obtain suitable color colourity with the dye coloring agent, provides simultaneously with pigment colorant to reach excellent water tolerance and photostabilization.Need especially a kind of like this ink/textile combination, it can reproduce and have sharp edge and a kind of color nonbleeding color picture information to another kind of color.

Tinting material can be dyestuff and pigment.Especially preferably use pigment.Dyestuff
The term of Shi Yonging " dyestuff " refers to certain the soluble tinting material that a bit becomes in printing process in the present invention.This term comprises two kinds of dyestuffs: be soluble in aqueous vehicle and the aqueous vehicle under the normal recipe condition in be insoluble.Dyestuff refers to known dispersed dye in nearest classification.
The dyestuff of Shi Yonging comprises anionic dyestuff in the present invention, zwitterionic dyestuff and non-ionic dye.These dyestuffs are known in the art.Anionic dyestuff produces painted negatively charged ion in aqueous solution.General anionic dyestuff contains as the carboxylic acid or the sulfonic acid group of ion part and comprises all matching stains.
The kind of the most frequently used anionic dyestuff is a matching stain among the present invention, substantive dyestuff, food dye, mordant dye, and reactive dyestuffs.Anionic dyestuff is a nitroso compound, nitro-compound, azo-compound, third constellations compound, triaryl methane compounds, xanthenes compound, quinoline compound, thiazolium compounds, bifurcation piperazine compound, oxazines compound, thiazine compounds, amino ketone compound, anthraquinone compounds, indigoid compound and phthalocyanine compound.
The color of employed dyestuff and amount mainly change with the function of selecting in ink composite, and these selections depend primarily on people and wish color with the printed matter of this printing ink acquisition, the purity of dyestuff and intensity.The concentration of dyestuff is low can not to reach enough bright-colored good.High density may cause printing head performance to reduce or not satisfied dead color.The amount of dyestuff accounts for the 0.01-20% weight of total weight, preferred 0.05-8% weight, more preferably 1-5% weight.Pigment
The term of Shi Yonging " pigment " refers to keep the tinting material of crystalline or graininess in printing process in the present invention.Can select organic or inorganic pigment separately or with combining form.The functional group that pigment dyestuff contains (for example, acid, alkali, epoxy group(ing) and carboxyl) can react with the medium composition of selecting the superior in special applications.
Enough little of to allow printing ink unrestricted flow by ink-jet printing apparatus of pigment particle particularly typically has a diameter from the nozzle of 10-50 micron.Particle size is also influential to dispersing of pigments stability, and dispersion stabilization is very crucial in whole printing ink lifetime.The pedesis meeting of micro particles helps prevent the particulate sedimentation.People also wish to use micro particles to connect maximum colour intensity.The scope of used particle size is about 0.005-15 micron.The pigment particle size is preferably the 0.005-5 micron, more preferably the 0.01-0.3 micron.
Can use selected pigment with dry or wet form.Generally pigment is made water-bearing media and obtained product pigment with the water wet cake.In cake form, pigment is assembled unlike dried forms.Therefore, depolymerization the pigment of water wet-cake form does not need in the method for preparing printing ink with dried pigment.The dried pigment of spendable typical commercialization and the advantage of filter cake pigment are disclosed in U.S. Pat 5085698.
The trickle particulate of metal or metal oxide also can be used to implement the present invention.For example, metal or metal oxide are suitable for the preparation of magnetic jetted ink.Also can select trickle particulate oxide thing, as silicon-dioxide, aluminum oxide, titanium dioxide or the like.In addition, can select the metal particle of fine powder such as copper, iron, steel, aluminium and alloy to be used for special purpose.
When selecting pigment dyestuff, printing ink can contain the pigment up to about 30% weight, but is used for the hottest ink jet printing purposes, and pigment generally is in the scope of 0.1-15% weight (preferred 0.1-8% weight).If the selection mineral dye is compared with the similar printing ink that uses pigment dyestuff, printing ink tends to contain the pigment of higher weight per-cent, under certain conditions can be up to about 75%, and this is because mineral dye is compared with pigment dyestuff and generally had higher proportion.
Generally the pigment (dispersed dye) that uses as tinting material needs dispersion agent and tensio-active agent to help to keep insoluble tinting material in the water ballast toner.Polymeric dispersant is the dispersion agent, particularly topology convergence dispersion agent of the most normal selection.Polymkeric substance
In preferred embodiments, printing ink contains polymkeric substance.Polymkeric substance can be used as the dispersion agent of insoluble tinting material (being pigment or dispersed dye) or as tackiness agent.Polymkeric substance is structural polymer such as AB or BAB segmented copolymer (for example referring to U.S. Pat 5085698) preferably, ABC triblock copolymer (for example referring to european patent application 0556649A1), or branched polymer or graftomer (for example referring to U.S. Pat 5231131).
Though random copolymers can be used as dispersion agent and uses, they are effective not as structure copolymer aspect the stable pigments dispersiveness, are not preferred therefore.The random copolymer that uses has narrow may command molecule weight range, and this scope preferably has 1.3 polymolecularity, and preferred 1.2.These polymkeric substance in fact are not have the higher molecular weight material of stopping up a nozzle easily.Number-average molecular weight must be less than 10000 dalton, and is preferably less than 6000 dalton, more preferably excellent in 3000 dalton.Random copolymers contains hydrophobic and hydrophilic monomeric units.The random dispersion multipolymer of commodity stops up a nozzle easily.But by use group transfer polymerization technology, or other provides low dispersed method can obtain the molecular weight that needs.The example that is used for the hydrophobic monomer of random copolymers is a methyl methacrylate, n-BMA, methacrylic acid (2-ethylhexyl) ester, benzyl methacrylate, methacrylic acid (2-styroyl) ester and corresponding acrylate.The example of hydrophilic monomer is a methacrylic acid, vinylformic acid, [methyl] vinylformic acid dimethylamino ethyl ester and its salt.
The polymeric bonding agent additive particularly has crosslinkable part, is also included within this ink formulations as the polymeric bonding agent additive of acid, hydroxyl, amine etc.They can be various types of, as the emulsion of linearity, comprise the core shell and by the stable emulsion of structural polymer, water-sol or the like.Alginate
These alginate are univalent ion salt or organic amine salt.Univalent ion salt is selected from sodium, potassium, lithium and ammonium.The trace calcium salt and the magnesium salts that can exist in the alginate do not have deleterious effect.The organic amine that uses comprises methylamine, dimethylamine, Trimethylamine 99, ethamine, diethylamine and triethylamine.
Alginate are made by the natural product ammonium alginate.Ammonium alginate is prepared by brown seaweed by the extracting method of complexity.Several brown algas are arranged.Macrocystis pyrifere is the primary commercial source of ammonium alginate.Other kind is Ascophyllum nodosum, and kelp belongs to digitata, and kelp belongs to hyperborea, and kelp belongs to cava, Eisenia bicyclis.The ammonium alginate polymkeric substance is made with 60: 40 ratio by D-mannuronic acid and L-Guluronic acid residue.It is believed that this polymkeric substance contains three kinds of segments: polymannuronic acid segment, poly-Guluronic acid segment and alternate cells segment.The ratio of these parts of the ammonium alginate that is obtained by Macrocystis pyrifere is 40: 20: 40.It is believed that poly-Guluronic acid segment links to each other with divalence that is connected polymer chain or trivalent ion.The alginate of preferably making mainly are sodium salts, but also can contain a spot of sylvite, calcium salt and magnesium salts.Other component
According to special purposes, can use various additives to improve the character of ink composite.In polymeric dispersant, can use anion surfactant, nonionogenic tenside, or amphoterics.Inventory as the non-polymeric tensio-active agent of some polymeric surfactants is listed in 1990 McCutcheon'sFunctional Materials, North American Edition, Manufacturing Confection Publishing Co., Glen Roek, the 110-129 page or leaf among the NJ.The selection of special tensio-active agent greatly depends on the kind of specialty inks composition and fabric to be printed.Those skilled in the art can select the suitable tensio-active agent that uses at the specialty inks composition that is used for special matrix.In aqueous ink, the amount of the tensio-active agent of existence is the 0.01-5% of total weight, is preferably 0.2-2%.
Can comprise the solubility promoter that penetrates and suppress to stop up character that improves ink composite, in fact preferably use solubility promoter.This solubility promoter is known in this area.The representative solubility promoter of preferential use has been described in U.S. Pat 5272201.Can use biocides to suppress microorganism growth.The example of this biocides is Dowicides (Dow Chemical, Midland, MI), Nuosept (Huls America, Inc., Piscataway, NJ), Omidines (Olin Corp., Cheshire, CT), Nopcocides (Henkel Corp., Ambler, PA), Troysans (Troy Chemical Corp., Newark, NJ) and Sodium Benzoate.Can comprise that also sequestrant such as EDTA eliminate the harmful effect of beavy metal impurity.Also can add other known additive such as wetting agent, viscosity modifier and other vinylformic acid or non-acrylate copolymer are to improve the various character of desirable ink composite.Ink property
The surface tension of printing ink and viscosity pole earth effect jet velocity, the gap length of ink droplet, the size of ink droplet and discharge stability.In the time of 20 ℃, be applicable to surface tension that the pigmented ink-jet printing ink of ink jet printing system has be about 20 dynes per centimeter-70 dynes per centimeter and, 30 dynes per centimeter-70 dynes per centimeter more preferably.In the time of 20 ℃, the viscosity of allowing is not more than 20cP and is preferably 1.0cP-10.0cP.The physical properties that printing ink has is suitable for injection conditions widely, be driving voltage and the pulse width that is used for hot ink-jet printing apparatus, be used for instant drippage (drop-on-demand) device or the driving frequency of continuous apparatus press member and the size and the shape of nozzle.Printing ink has fabulous long storage stability and does not stop up in ink-jet printing apparatus.Fixing printing ink rapidly and reliably on the medium of suitably handling.The printing ink image of printing has bright and bright-coloured tone.In addition, printing ink does not corrode the parts of the ink-jet printing apparatus that contacts with it, and essentially no smell and nontoxic.Purposes
