Definitions

  • the invention broadly relates to image receiving elements. More specifically, the invention relates to ink jet receptors, particularly porous ink jet receptors.
  • Inkjet printing is a printing technique in which images (e.g., graphs, pictures, symbols, text, etc.) are produced by the ejection of uniformly shaped droplets of ink onto the receptor surface of a recording sheet.
  • images e.g., graphs, pictures, symbols, text, etc.
  • This printing technique is widely used in the personal and small office markets. Other applications include low end proofing, and medical referral markets.
  • the maximum image resolution and throughput of an ink jet printer are primarily determined by the size of the jetted drop and the rate of drop ejection. Several factors limit ink jet printers from attaining the maximum image resolution capable of being achieved by the printer. One of these limiting factors is the nature of the recording sheet receiving the jetted drops.
  • Ink receptor surfaces can be divided into two basic types: continuous phase systems and discontinuous phase systems.
  • Continuous phase systems generally function by swelling to absorb water or ink deposited onto the receptor surface, with the rate of absorption determined by the chemical nature of the polymer used in the system.
  • Typical polymers used in continuous phase systems include gelatins, polyvinyl alcohol, and cellulose. Exemplary continuous phase systems are discussed in United States Patents Nos. 3,889,270, 4,503,111, and 5,141,599.
  • Discontinuous phase systems function by providing pores within the receptor surface capable of absorbing ink by capillary forces. Discontinuous phase systems are generally preferred over continuous phase systems as they absorb ink considerably faster than continuous phase systems.
  • a first type of a discontinuous phase system utilizes micron sized porous pigment particles in the recording layer for purposes of absorbing ink jetted onto the recording layer into the particles through a multitude of tiny interconnected pores in each particle.
  • Ink recording sheets having a porous, discontinuous phase system recording layer are disclosed in United States Patent Nos. 5,165,973; 5,270,103; 5,397,619; 5,478,631; International Published Application WO 97/01448.
  • a second alternative type of discontinuous phase system known as a nonporous discontinuous phase system" utilizes nonporous pigment particles held together by a polymeric binder in such a manner that interstitial voids are created between the pigment particles capable of absorbing ink jetted onto the receptor surface.
  • Inkjet recording sheets with a recording layer of the porous discontinuous phase system type generally provide good ink absorptivity and superior ink capacity, in exchange for some loss in the glossy appearance of the recording sheet.
  • ink jet recording sheets with a recording layer of the nonporous discontinuous phase system type provide superior ink absorptivity and a glossy appearance in exchange for a limited ink capacity due to practical limitations upon the thickness of the coating.
  • An ink jet recording sheet wherein the recording layer on the substrate has a thickness of at least 30 ⁇ m and includes a latex binder and a nonporous pigment having an average particle size of less than 500 nm.
  • the concentration of pigment in the recording layer exceeds the latex critical pigment volume concentration so as to provide pores within the recording layer.
  • Figure 1 is an enlarged side view of an end of one embodiment of the invention.
  • Figure 2 is a graph demonstrating the time required to absorb a drop of ink into a discontinuous nonporous recording layer relative to the diameter of the particles contained within the recording layer based upon equations [2] - [6] set forth herein.
  • absorptivity refers to the rate at which a drop of ink can be absorbed into the ink jet recording sheet (volume/time).
  • the term “capacity” refers to the amount of ink that can be absorbed into the ink jet recording sheet (volume).
  • the term "diameter”, when used in connection with a particle, means the longest measurement across the particle.
  • the phrase "essentially neutral charge", when used in connection with the recording layer, means that the recording layer does not include more than a trace amount of an intentionally added ionically charged constituent.
  • latex binder means an aqueous dispersion of water-insoluble polymeric particles.
  • the phrase “latex critical pigment volume concentration” refers to the highest pigment concentration in a polymer film before the onset of voids or pores in the film, (i.e., that point at which the concentration of latex binder is no longer sufficient to completely occupy the interstitial sites between pigment particles and a void volume is created within the layer).
  • nonporous pigment refers to a pigment particle which is essentially impermeable to ink (i.e., ink is not appreciably absorbed into the pigment particle).
  • the term "thickness”, when used in connection with the recording layer, means the thickness of the recording layer on a dry basis.
  • wt% is based upon the solids content of the composition (i.e., calculated on a dry basis).
  • Performance of the inkjet recording sheet 10 is dependent upon a number of variables, but is predominantly controlled by particle size and particle size distribution within the inkjet recording layer 40.
  • particle size and particle size distribution within the inkjet recording layer 40 As capillary theory dictates, the larger the size of the pores within the inkjet recording layer 40 the higher the absorption rate. Hence, absorption rate can be easily manipulated by altering particle size.
  • N 0 is the volume of the drop
  • x& is the diameter of the drop-receptor contact area
  • p p is the pore area density and R, ⁇ , ⁇ v , and ⁇ are as previously defined.
  • R the radius of the pores (R) influences the rate of absorption to the greatest extent (t ' .e., as the pore radius is increased the time to absorb a droplet decreases by the fifth power). Accordingly, the rate of absorption can be dramatically increased by a modest increase in the radius of the pores.
  • the contact angle the liquid makes with the porous material is also important (i.e., as the contact angle is increased the rate of absorption is decreased). Hence, it is desirable for the droplet to completely wet the porous surface of the inkjet recording sheet.
  • the recording layer 40 should have a high density of large diameter pores and provide good wetting of the ink on the surface of the recording layer 40.
  • the inkjet recording layer 40 is a porous film essentially formed by packing together many similarly size spherical particles into a packed bed (i.e., pigment particles and latex binder particles). For simplicity, the balance of this analysis will assume that the particles are spherical and of equal size (i.e., monodisperse).
  • a monodisperse bed of spheres when packed as tightly as possible will yield a void fraction of 26%.
  • 26% of the receptor volume is available for ink absorption.
  • the pore area density (p p ) at the surface of such a packed bed is represented by the formula:
  • Pores within a packed bed of spheres are unlike the capillary tubes modeled above. Rather, pores formed by a bed of spheres can be approximated by a capillary tube of the same radius as a sphere that just passes through the opening formed by three neighboring spheres. This radius, known as the Haines in-sphere radius (H r ), is calculated as: where r is as previously defined.
  • the discontinuous inkjet recording sheet 10 includes a thick coating of a discontinuous recording layer 40 on a suitable substrate 20, wherein the recording layer 40 provides excellent ink absorptivity and capacity with good integrity.
  • the substrate 20 may be any of the typical materials used in the construction of ink jet recording sheets capable of providing the necessary visual appearance and structural support for the recording layer(s) 40.
  • suitable substrates include paper, cloth, polymers, metals, and glass.
  • Thin flexible sheets are generally preferred, with paper the substrate of choice when an opaque support is desired, and polymeric films used when a translucent or transparent appearance is desired.
  • the thickness of the substrate 20 is preferably in the range of about 0.05 to 1.0 mm.
  • the major surface of the substrate 20 to be coated with the recording layer 40 may optionally be treated with a subbing layer 30, such as a primer or an antistatic layer, before the recording layer 40 is coated onto the substrate 20.
  • a subbing layer 30, such as a primer or an antistatic layer such as a primer or an antistatic layer
  • the recording layer 40 is comprised of a nonporous pigment held together by a latex binder.
  • the recording layer 40 should be at least about 30 ⁇ m thick in order to provide sufficient capacity. Recording layers 40 possessing acceptable appearance can be formed up to a thickness of about 100 ⁇ m, with a thickness of between about 35 to 85 ⁇ m preferred.
  • Pigments suitable for use include any of the conventional nonporous pigments used in the production of coated paper, including specifically, but not exclusively, nonporous types of (i) inorganic pigments such as alumina, aluminum hydroxide, aluminum oxide, aluminum silicate, barium sulfate, calcium carbonate, calcium silicate, calcium sulfate, kaolin, magnesium silicate, silica, silicic acid, sodium silicate, talc, titania, titanium dioxide zinc carbonate, zinc oxide, and mixtures thereof, (ii) organic pigments such as plastic pigments, urea resin pigments, and mixtures thereof, and (iii) mixtures of inorganic and organic pigments.
  • inorganic pigments such as alumina, aluminum hydroxide, aluminum oxide, aluminum silicate, barium sulfate, calcium carbonate, calcium silicate, calcium sulfate, kaolin, magnesium silicate, silica, silicic acid, sodium silicate, talc, titania, titanium dioxide zinc carbonate,
  • Pigments having an average particle size of less than 500 nm are capable of producing a recording layer 40 having the desired appearance and performance. Pigment particles having an average particle size of between about 10 - 500 nm are generally preferred, with pigment particles having an average particle size of between about 50 -300 nm desired and pigment particles having an average particle size of between about 50 -100 nm favored.
  • the pigment particles can be of substantially any desired shape, with symmetrical particles, particularly spherical particles, generally preferred as they enhance the performance characteristics of the recording layer 40.
  • the nonporous pigment particles are held together by a latex binder.
  • the latex binder is provided in an amount sufficient to hold the pigment particles together and provide an acceptable appearance, while producing a pigment volume concentration above the latex critical pigment volume concentration so as to leave pores (i.e., interconnected interstitial voids) within the recording layer 40 and thereby enhance performance.
  • Ink jetted onto a recording layer 40 having a pigment concentration above the latex critical pigment volume concentration will be channeled into and stored within the pores in the layer 40 through capillary action.

  • discontinuous films will have a A > 1, while continuous films will have a A ⁇ 1.
  • LCPNC pigment latex film
  • Equation [8] can be rearranged to relate the volume of pigment needed to reach the LCPNC:
  • Equation [9] describes the effect of particle geometry on LCPNC or the minimum pigment concentration required to form a porous film. It is noted that as pigment particles become larger more pigment is required to form a porous film. Conversely, as latex particles become larger, less pigment is needed to produce a porous film. It is generally preferred that the latex particles used in the recording layer 40 have a diameter at least as large as the diameter of the pigment particles, with latex particles having a diameter at least V ⁇ times greater than the diameter of the pigment particles most preferred. This geometrical dependency can be used to manipulate the porosity of a pigment latex film. By choosing a pigment particle size, latex particle size and latex volume, the absorption requirements can be met.
  • T g Other properties of the latex can effect LCPNC, such as T g .
  • T g A latex with a high T g is not very soft and tends to coalesce slowly, retarding movement of the latex into the pores and yielding a lower LCPNC.
  • a latex that does not wet the pigment well will not move readily into the pores and will yield a lower LCPVC.
  • latex binder increases a number of desired properties and characteristics of the recording layer 40, such as increasing integrity and wear resistance, reducing cracking, improving adhesion to the substrate 20.
  • binder causes A to move towards 1, signaling a decrease in porosity and a decrease in performance.
  • a careful consideration of binder concentration is necessary to create a suitable inkjet recording layer 40 having a proper balance of performance characteristics.
  • a weight ratio of pigment to latex of about 5: 1 to 10: 1, preferably about 6:1 to 8:1, provides acceptable balancing of the competing performance characteristics.

  • An anti-curl layer 50 may optionally be coated on the back side of the substrate 20.
  • any convenient method may be employed to blend the constituents together to form the recording layer composition.
  • Exemplary procedures include, (i) dispersing the pigment in water and then adding the aqueous latex binder into the aqueous dispersion of pigment, (ii) dispersing the pigment in water and then adding the aqueous dispersion of pigment into the aqueous latex binder, (iii) simultaneously charging the pigment and the latex binder into a suitable mixer such as an agitator.
