Definitions

  • the present invention relates to an improved recording element for ink jet printing.
  • ink jet printing has become a technology of choice.
  • a recent survey on progress and trends in ink jet printing technology is given by Hue P. Le in Journal of Imaging Science and Technology Vol. 42 (1), Jan/Febr 1998.
  • tiny drops of ink fluid are projected directly onto an ink receptor surface without physical contact between the printing device and the receptor.
  • the printing device stores the printing data electronically and controls a mechanism for ejecting the drops image-wise. Printing is accomplished by moving the print head across the paper or vice versa.
  • Early patents on ink jet printers include US 3,739,393, US 3,805,273 and US 3,891,121.
  • the jetting of the ink droplets can be performed in several different ways.
  • a continuous droplet stream is created by applying a pressure wave pattern.
  • This process is known as continuous ink jet printing.
  • the droplet stream is divided into droplets that are electrostatically charged, deflected and recollected, and into droplets that remain uncharged, continue their way undeflected, and form the image.
  • the charged deflected stream forms the image and the uncharged undeflected jet is recollected.
  • several jets are deflected to a different degree and thus record the image (multideflection system).
  • the ink droplets can be created “on demand” (“DOD” or “drop on demand” method) whereby the printing device ejects the droplets only when they are used in imaging on a receiver thereby avoiding the complexity of drop charging, deflection hardware, and ink recollection.
  • DOD on demand
  • the ink droplet can be formed by means of a pressure wave created by a mechanical motion of a piezoelectric transducer (so-called “piezo method”), or by means of discrete thermal pushes (so-called “bubble jet” method, or “thermal jet” method).
  • Ink compositions for ink jet typically include following ingredients : dyes or pigments, water and/or organic solvents, humectants such as glycols, detergents, thickeners, polymeric binders, preservatives, etc.. It will be readily understood that the optimal composition of such an ink is dependent on the ink jetting method used and on the nature of the substrate to be printed.
  • the ink compositions can be roughly divided in :
  • binders of which the most common types are gelatin, polyvinyl alcohol, polyvinyl pyrrolidone, and various types of cellulose derivatives. These conventional binders are mentioned in numerous patent documents.
  • a two-layer ink jet printing medium comprising a liquid-absorbent base material, an ink receiving layer provided on the base material, which comprises a pigment, a binder, and a cationic substance, and a surface layer provided on the ink receiving layer comprising ultrafine cationic particles.
  • Embodiments according to this teaching show improved glossiness and high optical density after printing. However, they need still further improvement for water-fastness, bleeding and color gamut.
  • the present invention further extends the teachings on two-layer ink jet recording materials with improved properties.
  • the present invention discloses an ink jet recording element comprising, in order, a support, and, on at least one side of said support,
  • the main pigment is chosen from silica, aluminosilicate, alumina, calcium carbonate, alumina hydrate, and aluminum trihydroxide. Most preferred are aluminum containing pigments.
  • the cationic substance is preferably chosen from boehmite, cationized silica or mixtures thereof.
  • Both ink receiving layers can be coated on just one side of the support, or they can be present on both sides of the support, in which latter case the corresponding layers can show the same or a different composition.
  • the second side of the support may carry one or more backing layers, different in composition from the definition of the ink receiving layers.
  • the recording element may further comprise at least one adhesive undercoat layer. Actual embodiments of ink jet recording media according to the present invention show improved water-fastness, bleeding drying time, color gamut properties, and reduced coalescence.
  • the support for use in the present invention can be chosen from the paper type and polymeric type support well-known from photographic technology.
  • Paper types include plain paper, cast coated paper, a paper carrying a barrier layer preventing ink penetration, polyethylene coated paper and polypropylene coated paper.
  • Polymeric supports include cellulose acetate propionate or cellulose acetate butyrate, polyesters such as polyethylene terephthalate (PET) and polyethylene naphthalate, polyvinyl chloride, polyamides, polycarbonates, polyimides, polyolefins, poly(vinylacetals), polyethers and polysulfonamides.
  • PET polyethylene terephthalate
  • polyethylene naphthalate polyvinyl chloride
  • polyamides polycarbonates
  • polyimides polyolefins
  • poly(vinylacetals) polyethers and polysulfonamides.
  • polyethylene terephthalate examples include opaque white polyesters and extrusion blends of polyethylene terephthalate and polypropylene.
  • polyester film supports, and especially polyethylene terephthalate are preferred because of their excellent properties of dimensional stability.
  • a resin coated paper support is preferred.
  • the support is coated with at least two ink receiving layers, called first and second ink receiving layers, which will be now explained successively in more detail.
  • first and second ink receiving layers which will be now explained successively in more detail.
  • the first layer is a rather thick layer and can be regarded as the bulk ink receiving layer.
  • the first ink receiving layer contains, apart from a binder and a main absorptive pigment, pseudo-boehmite in an amount of 1 to 30 % by weight versus the main pigment.

  • a preferred binder for the practice of the present invention is a polyvinylalcohol (PVA), a vinylalcohol copolymer or modified polyvinyl alcohol.
  • PVA polyvinylalcohol
  • the polyvinyl alcohol is a cationic type polyvinyl alcohol, such as the cationic polyvinyl alcohol grades from Kuraray, such as POVAL C506, POVAL C118, and from Nippon Goshei.

  • the composition thereof is generally represented by Al 2 O 3 . 1.5-2 H 2 O and differs from that of crystalline boehmite.
  • the incorporation of pseudo-boehmite in the first ink receiving layer brings the following surprising advantages for the ink jet recording medium : improvements for water-fastness and bleeding, and reduced coalescence.

If the amount of the pigment exceeds the upper limit, the strength of the ink receiving layer itself is lowered, and the resulting image hence tends to deteriorate in rub-off resistance and the like. On the other hand, if the binder to pigment ratio is too great, the ink-absorbing capacity of the resulting ink-receiving layer is reduced, and so the image formed may possibly be deteriorated.

  • the dry thickness of the upper ink receiving layer is preferably comprised between 10 and 40 % vis-à-vis the dry thickness of the bulk layer.
  • the first and second ink receiving layers may be coated on just one side of the support, or they may be applied on both sides of the support.
