Description
- The present invention relates to an ink jet recording element containing a stabilizer and a printing method using the element.
- In a typical ink jet recording or printing system, ink droplets are ejected from a nozzle at high speed towards a recording element or medium to produce an image on the medium. The ink droplets, or recording liquid, generally comprise a recording agent, such as a dye or pigment, and a large amount of solvent. The solvent, or carrier liquid, typically is made up of water and an organic material such as a monohydric alcohol, a polyhydric alcohol or mixtures thereof.
- An ink jet recording element typically comprises a support having on at least one surface thereof an ink-receiving or image-receiving layer, and includes those intended for reflection viewing, which have an opaque support, and those intended for viewing by transmitted light, which have a transparent support.
- An important characteristic of ink jet recording elements is their need to dry quickly after printing. To this end, porous recording elements have been developed which provide nearly instantaneous drying as long as they have sufficient thickness and pore volume to effectively contain the liquid ink. For example, a porous recording element can be manufactured by coating in which a particulate-containing coating is applied to a support and is dried.
- When a porous recording element is printed with dye-based inks, the dye molecules penetrate the coating layers. However, there is a problem with such porous recording elements in that the optical densities of images printed thereon are lower than one would like. The lower optical densities are believed to be due to optical scatter that occurs when the dye molecules penetrate too far into the porous layer. Another problem with a porous recording element is that atmospheric gases or other pollutant gases readily penetrate the element and lower the optical density of the printed image causing it to fade. Still another problem occurs from microcracking of the surface of the coated layer that leads to a nonhomogeneous coverage of ink in the ink receiving layer. It would be desirable that such coated elements have high gloss, waterfastness and high ink capacity.
- EP 1 016 543 relates to an ink jet recording element containing aluminum hydroxide in the form of boehmite. However, there is a problem with this element in that it is not stable to light and exposure to atmospheric gases.
- EP 0 965 460A2 relates to an ink jet recording element containing aluminum hydrate having a boehmite structure and a non-coupling zirconium compound. However, there is no specific teaching of a metal oxy(hydroxide) complex as described herein.
- U.S. Patent 5,372,884 relates to ink jet recording elements containing a hydrous zirconium oxide. However, there is a problem with such elements in that they tend to fade when subjected to atmospheric gases, as will be shown hereafter.
- JP 04 007189 A (Abstract) discloses an inkjet recording element comprising a support having thereon an image-receiving layer comprising a porous pigment and a metal(oxy)hydroxide complex, exemplified by zirconium salts. The salts are added to the porous pigment in the coating composition.
- JP 10 226153 A, EP-A-0 391 308 and EP-A-1 112 962 disclose inkjet recording elements comprising aluminum hydrates or basic aluminum salts such as boehmite.
- It is an object of this invention to provide an ink jet recording element that, when printed with dye-based inks, provides superior optical densities, good image quality and has an excellent dry time.
- Still another object of this invention is to provide a printing method using the above-described element.
- These and other objects are achieved in accordance with the invention which comprises an ink jet recording element comprising a support having thereon an image-receiving layer, said image-receiving layer containing finely divided particulate material and, in addition, a metal(oxy)hydroxide complex coated in particulate form,
Mn+(O)a(OH)b(Ap-)c•xH2O,
wherein - Mn+ is at least one metal ion wherein M is a Group IVA, IVB metal or lanthanide group metal of the periodic chart;
- n is 4;
- Ap- is an organic or inorganic ion;
- p is 1, 2 or 3; and
- x is equal to or greater than 0;
- 0<a<2;0<b<4; and 0 < pc ≤ 4, so that the charge of the M4+ metal ion is balanced.
- By use of the invention, an ink jet recording element is obtained that, when printed with dye-based inks, provides superior optical densities, good image quality and has an excellent dry time and image stability.
- Another embodiment of the invention relates to an ink jet printing method comprising the steps of:
- A) providing an ink jet printer that is responsive to digital data signals;
- B) loading the printer with the ink jet recording element described above;
- C) loading the printer with an ink jet ink composition; and
- D) printing on the ink jet recording element using the inkjet ink composition in response to the digital data signals.
- The stabilizer complex described above is located in the image-receiving layer. M in the above formula is a Group IVA, IVB metal or a lanthanide group metal of the periodic chart, such as, for example, titanium, zirconium, silica or lanthanum or mixtures thereof. The stabilizer described above is in a particulate form. In another preferred embodiment, n is 4; a, b and c each comprise a rational number as follows: 0 < a < 1; 1 < b < 4; and 1 < pc < 4, so that the charge of the M4+ metal ion is balanced.
- In yet still another preferred embodiment of the invention, Ap- is an organic anion such as R-COO-, R-O-, R-SO3 -, R-OSO3 - or R-O-PO3 - where R is an alkyl or aryl group. In another preferred embodiment, Ap- is an inorganic anionic such as I-, Cl-, Br-, F-, ClO4 -, NO3 -, CO3 2- or SO4 2-. The particle size of the complex described above is less than 1 µm, preferably less than.0.1 µm.
- Metal (oxy)hydroxide complexes employed herein may be prepared by dissolving a metal salt in water and adjusting the concentration, pH, time and temperature to induce the precipitation of metal (oxy)hydroxide tetramers, polymers or particulates. The conditions for precipitation vary depending upon the nature and concentrations of the counter ion(s) present and can be determined by one skilled in the art. For example, soluble complexes suitable for preparation of the zirconium (oxy)hydroxide particulates include, but are not limited to, ZrOCl2·8H2O, and the halide, nitrate, acetate, sulfate, carbonate, propionate, acetylacetonate, citrate and benzoate salts; and hydroxy salts with any of the above anions. It is also possible to prepare the complexes employed in the invention via the hydrolysis of organically soluble zirconium complexes such as zirconium alkoxides, e.g., zirconium propoxide, zirconium isopropoxide, zirconium ethoxide and related organometallic zirconium compounds.
- The hydrolyzed zirconium oxyhydroxides,
Zr(O)a(OH)b(AP-)c*xH2O
may exist as tetrameric zirconia units or as polymeric complexes of tetrameric zirconia, wherein zirconium cations are bridged by hydroxy and/or oxo groups. In general, hydrolyzed zirconia salts are amorphous and may exist predominantly in the α form. However, depending upon the experimental conditions (solvents, pH, additives, aging and heating conditions), the hydrolyzed product may contain significant number of "oxo" bridges. - It is often difficult to ascertain the precise composition of "oxo" and "hydroxy" groups in hydrolyzed metal salts. Therefore, the usage of definitive numbers for these functional groups in metal (oxy)hydroxide compositions was avoided. Any number of oligomeric or polymeric units of metal complexes may be condensed via hydrolysis reactions to form larger particulates ranging in size from 3 nm to 500 nm.
- It is further possible to age or heat treat suspensions of the complexes to obtain particulates ranging in size from 0.500 µm to 5.0 µm. Preferred particles sizes are in the range from 5 nm to 1000 nm. Calcination of amorphous metal (oxy)hydroxide leads to the formation of crystalline polymorphs of metal oxides.
- In a preferred embodiment of the invention, the finely divided particulate material is a water-insoluble inorganic solid or polymeric material, such as a metal oxide or an inorganic mineral. Examples of water-insoluble inorganic solids include any inorganic oxide, such as silica, colloidal silica, fumed silica, alumina, hydrous alumina, colloidal alumina, fumed alumina, calcium carbonate, kaolin, talc, calcium sulfate, natural or synthetic clay, barium sulfate, titanium dioxide, zinc oxide, or mixtures thereof.
- Examples of polymeric materials which can be used in the invention as particulate materials include latex particles and core-shell latex particles, such as polyolefins, polyethylene, polypropylene, polystyrene, poly(styrene-co-butadiene), polyurethane, polyester, poly(acrylate), poly(methacrylate), copolymers of n-butylacrylate and ethylacrylate, copolymers of vinylacetate and n-butylacrylate, copolymers of methyl methacrylate and sodium 2-sulfo-1,1-dimethylethyl acrylamide, and copolymers of ethyl acrylate, vinylidene chloride and sodium 2-sulfo-1,1-dimethylethyl acrylamide or mixtures thereof. These polymers can be internally crosslinked or uncrosslinked. It is preferable that uncrosslinked latex particles have a film formation temperature above 25 °C.
- The polymeric particles and inorganic particles useful in the invention can be of any size. In a preferred embodiment, the mean particle diameter is less than 1 µm. Mixtures of organic and inorganic particles may also be used.
- In a preferred embodiment of the invention, the image-receiving layer is porous and also contains a polymeric binder in an amount insufficient to alter the porosity of the porous receiving layer. In another preferred embodiment, the polymeric binder is a hydrophilic polymer such as poly(vinyl alcohol), poly(vinyl pyrrolidone), gelatin, cellulose ethers, poly(oxazolines), poly(vinylacetamides), partially hydrolyzed poly(vinyl acetate/vinyl alcohol), poly(acrylic acid), poly(acrylamide), poly(alkylene oxide), sulfonated or phosphated polyesters and polystyrenes, casein, zein, albumin, chitin, chitosan, dextran, pectin, collagen derivatives, collodian, agar-agar, arrowroot, guar, carrageenan, tragacanth, xanthan, rhamsan and the like. In still another preferred embodiment of the invention, the hydrophilic polymer is poly(vinyl alcohol), hydroxypropyl cellulose, hydroxypropyl methyl cellulose, or a poly(alkylene oxide). In yet still another preferred embodiment, the hydrophilic binder is poly(vinyl alcohol).
- In addition to the image-receiving layer, the recording element may also contain a base layer, next to the support, the function of which is to absorb the solvent from the ink. Materials useful for this layer include particles, polymeric binder and/or crosslinker.
- The support for the ink jet recording element used in the invention can be any of those usually used for ink jet receivers, such as resin-coated paper, paper, polyesters, or microporous materials such as polyethylene polymer-containing material sold by PPG Industries, Inc., Pittsburgh, Pennsylvania under the trade name of Teslin ®, Tyvek® synthetic paper (DuPont Corp.), and OPPalyte® films (Mobil Chemical Co.) and other composite films listed in U.S. Patent 5,244,861. Opaque supports include plain paper, coated paper, synthetic paper, photographic paper support, melt-extrusion-coated paper, and laminated paper, such as biaxially oriented support laminates. Biaxially oriented support laminates are described in U.S. Patents 5,853,965; 5,866,282; 5,874,205; 5,888,643; 5,888,681; 5,888,683; and 5,888,714. These biaxially oriented supports include a paper base and a biaxially oriented polyolefin sheet, typically polypropylene, laminated to one or both sides of the paper base. Transparent supports include glass, cellulose derivatives, e.g., a cellulose ester, cellulose triacetate, cellulose diacetate, cellulose acetate propionate, cellulose acetate butyrate; polyesters, such as poly(ethylene terephthalate), poly(ethylene naphthalate), poly(1,4-cyclohexanedimethylene terephthalate), poly(butylene terephthalate), and copolymers thereof; polyimides; polyamides; polycarbonates; polystyrene; polyolefins, such as polyethylene or polypropylene; polysulfones; polyacrylates; polyetherimides; and mixtures thereof. The papers listed above include a broad range of papers, from high end papers, such as photographic paper to low end papers, such as newsprint. In a preferred embodiment, polyethylene-coated paper is employed.
- The support used in the invention may have a thickness of from 50 to 500 µm, preferably from 75 to 300 µm. Antioxidants, antistatic agents, plasticizers and other known additives may be incorporated into the support, if desired.
- In order to improve the adhesion of the ink-receiving layer to the support, the surface of the support may be subjected to a corona-discharge treatment prior to applying the image-receiving layer.
- Coating compositions employed in the invention may be applied by any number of well known techniques, including dip-coating, wound-wire rod coating, doctor blade coating, gravure and reverse-roll coating, slide coating, bead coating, extrusion coating, curtain coating and the like. Known coating and drying methods are described in further detail in Research Disclosure no. 308119, published Dec. 1989, pages 1007 to 1008. Slide coating is preferred, in which the base layers and overcoat may be simultaneously applied. After coating, the layers are generally dried by simple evaporation, which may be accelerated by known techniques such as convection heating.
- In order to impart mechanical durability to an ink jet recording element, crosslinkers that act upon the binder discussed above may be added in small quantities. Such an additive improves the cohesive strength of the layer. Crosslinkers such as carbodiimides, polyfunctional aziridines, aldehydes, isocyanates, epoxides, polyvalent metal cations, and the like may all be used.
- To improve colorant fade, UV absorbers, radical quenchers or antioxidants may also be added to the image-receiving layer as is well known in the art. Other additives include inorganic or organic particles, pH modifiers, adhesion promoters, rheology modifiers, surfactants, biocides, lubricants, dyes, optical brighteners, matte agents, antistatic agents, etc. In order to obtain adequate coatability, additives known to those familiar with such art such as surfactants, defoamers, alcohol and the like may be used. A common level for coating aids is 0.01 to 0.30 % active coating aid based on the total solution weight. These coating aids can be nonionic, anionic, cationic or amphoteric. Specific elements are described in MCCUTCHEON's Volume 1: Emulsifiers and Detergents, 1995, North American Edition.
- The ink receiving layer employed in the invention can contain one or more mordanting species or polymers. The mordant polymer can be a soluble polymer, a charged molecule, or a crosslinked dispersed microparticle. The mordant can be non-ionic, cationic or anionic.
- The coating composition can be coated either from water or organic solvents, however water is preferred. The total solids content should be selected to yield a useful coating thickness in the most economical way, and for particulate coating formulations, solids contents from 10-40% are typical.
- Ink jet inks used to image the recording elements of the present invention are well-known in the art. The ink compositions used in ink jet printing typically are liquid compositions comprising a solvent or carrier liquid, dyes or pigments, humectants, organic solvents, detergents, thickeners, preservatives, and the like. The solvent or carrier liquid can be solely water or can be water mixed with other water-miscible solvents such as polyhydric alcohols. Inks in which organic materials such as polyhydric alcohols are the predominant carrier or solvent liquid may also be used. Particularly useful are mixed solvents of water and polyhydric alcohols. The dyes used in such compositions are typically watersoluble direct or acid type dyes. Such liquid compositions have been described extensively in the prior art including, for example, U.S. Patents 4,381,946; 4,239,543 and 4,781,758.
- The following examples are provided to illustrate the invention.
- The dye used for testing was a magenta colored ink jet dye having the structure shown below. To assess dye stability on a given substrate, a measured amount of the ink jet dye and solid particulates or aqueous colloidal dispersions of solid particulates (typically about 10%-20.0% by weight solids) were added to a known amount of water such that the concentration of the dye was about 10-5 M. The solid dispersions containing dyes were carefully stirred and then spin coated onto a glass substrate at a speed of 1000-2000 rev/min. The spin coatings obtained were left in ambient atmosphere with fluorescent room lighting (about 0.5 Klux) kept on at all times during the measurement. The fade time was estimated by noting the time required for complete disappearance of magenta color as observed by the naked eye or by noting the time required for the optical absorption to decay to less than 0.03 of the original value.
- Inorganic particles of Al2O3, SiO2, TiO2, ZnO, MgO, ZrO2, Y2O3, CeO2, CaCO3, BaSO4, Zn(OH)2, laponite and montmorillonite were purchased from commercial sources as fine particles or as colloidal particulate dispersions and were used to evaluate the stability of ink jet dyes in comparison with the materials employed in the present invention. The compositions and chemical identity of the samples was confirmed using powder X-ray diffraction techniques. The particulates were then coated and tested and the results are shown in Table 1.
