Definitions

  • the present invention relates to an ink jet recording element containing a stabilizer and a printing method using the element.
  • 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.
  • 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.
  • a porous recording element can be manufactured by coating in which a particulate-containing coating is applied to a support and is dried.
  • EPA 1174279A teaches the use of zinc oxide in ink jet recording elements to improve light stability. However, there is problem with such elements in that they do not provide protection against environmental gasses such as ozone.
  • EPA 988993A and EPA 893270A disclose the use of aluminum hydrate and aluminum hydroxides in ink jet recording elements. However, there is a problem with these elements in that they do not provide good image stability.
  • Still another object of the invention is to provide a printing method using the above-described element.
  • 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.
  • the metal hydroxide salt described above is located in the image-receiving layer.
  • M can be two different metal ions such as zinc and tin.
  • the metal hydroxide salt described above is in a particulate form.
  • a is greater than 0.5 and b is less than 1.5.
  • a p- is an organic anion such as R-COO - , R-O - , R-SO 3 - , R-OSO 3 - or R-O-PO 3 - where R is an alkyl or aryl group.
  • a p- is an inorganic anionic such as I - , Cl - , Br - , F - , ClO 4 - , NO 3 - , CO 3 2- or SO 4 2- .
  • the particle size of the salt described above is less than aout 5 ⁇ m, preferably less than 1 ⁇ m.
  • M 2+ hydroxide salts can be synthesized from a variety of synthetic routes, such as addition of base to metal salts, reacting a metal salt with a metal oxide or through ion exchange. Some of the M 2+ hydroxide salts form layered structures and are commonly referred to as hydroxy double salts. However, M 2+ hydroxides can also exist as polycationic nanoparticles. It is possible to control particle size, shape and structure of M 2+ hydroxide salts using appropriate anions or metal ions or synthetic routes.
  • M 2+ useful in the invention include zinc, magnesium, barium, calcium, tin, nickel, cobalt and copper.
  • M 2+ hydroxide salts include zinc hydroxy double salts such as Zn 5 (OH) 8 (A p- ), wherein A p- is Cl, Br, nitrate, acetate or propionate.
  • 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.
  • 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.
  • the hydrophilic polymer is poly(vinyl alcohol), hydroxypropyl cellulose, hydroxypropyl methyl cellulose, or a poly(alkylene oxide).
  • the hydrophilic binder is poly(vinyl alcohol).
  • 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.
  • 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 ⁇ m, preferably from 75 to 300 ⁇ m.
  • Antioxidants, antistatic agents, plasticizers and other known additives may be incorporated into the support, if desired.
  • 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.
  • crosslinkers which 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.
  • UV absorbers 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.
  • 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.
  • the 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 dye used for testing was a magenta colored ink jet dye having the structure shown below.
  • a measured amount of the ink jet dye and solid particulates or aqueous colloidal dispersions of solid particulates were added to a known amount of water such that the concentration of the dye was 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 (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.
  • the results are shown in Table 1.
  • Inorganic particles of Al 2 O 3 , SiO 2 , ZnO, 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 particulates were then coated and tested as described above.
