Definitions

  • This invention relates to a glossy ink jet receiving paper that can be used for high resolution color ink jet printing applications.
  • ink jet printing technology has been used for presentation, graphic art, engineering drawing and home office applications.
  • the performance requirements for ink jet media that are used for these applications are quite stringent. These include fast ink drying, low ink migration, large color gamut, good color fidelity, minimal ink offset, high image resolution and good performance under varied environmental conditions.
  • Another important requirement for ink jet media in commercial applications is high surface gloss. This is particularly important for graphic art applications.
  • Current commercial ink jet media cannot meet these performance requirements. For example, plastic substrate based ink jet media cannot offer high image resolution and fast drying, and most commercial ink jet papers cannot overcome low gloss and poor color fidelity.
  • U.S. Patent 5,141,599 discloses a glossy ink jet receiving material based on a polyolefin coated paper, but the coated paper performs more like a plastic film than a paper.
  • U.S. Patent 4,092,457 disclosed an ink receiving material based on synthetic fibers that do not offer desired paper properties. Further, U.S.
  • Patents 5,141,797, 5,279,885, 5,213,873, 5,207,824, 5,180,624, 4,542,059, 5,281,467, 5,302,437, 5,126,010, 5,013,603, 4,952,943, 4,900,620 all discuss ink jet receiving papers, but all of these designs ignored two important performance parameters, namely, gloss and ink migration. The provision of an ink jet receiving paper which can satisfy both of these performance requirements would be an important achievement in the art.
  • An objective of the present invention is to provide an ink jet receiving sheet which overcomes the above-mentioned drawbacks and problems which previously existed in the art.
  • the present invention provides an ink jet receiving paper for use in applications wherein high gloss, good image resolution and color fidelity are required. More specifically, the present invention provides an ink jet receiving paper with improved gloss, image resolution, color fidelity, ink migration, dry time and environmental tolerance. The present invention offers an ink jet receiving paper giving optimal performance in this respect, through the provision of unique combinations of ink receptive coatings and paper substrates having specified properties, wherein the resulting ink jet receiving paper fully meets the physical and performance requirements of commercial ink jet recording media.
  • a glossy ink jet receiving paper which comprises:
  • the surface of the prepared glossy ink jet receiving paper media encompassed by the present invention should possess the following characteristics:
  • the ink receptive coating provides an image forming layer
  • the paper substrate provides a base for handling as well as a reservoir for an ink vehicle.
  • any kind of paper can be used as the paper substrate, so long as it meets the above described parameters for gloss, Sheffield smoothness, opacity and brightness.
  • a clay-coated paper meeting such parameters is thought to be preferred.
  • Exemplary of suitable paper substrates which may be used in the present invention are clay-coated papers, such as Reflections II grade paper (Consolidated Paper Inc.), MultiArt Gloss grade paper (Stora Papyrus Newton Falls, Inc.), Tahoe Gloss grade paper (Simpson Paper Company), Evergreen Gloss paper (Simpson Paper Company) and the like.
  • the base weight of the paper is not particularly restricted, but should generally be in the range of about 30 g/m 2 to about 250 g/m 2 , preferably about 50 g/m 2 to about 150 g/m 2 .
  • the paper substrate may be pretreated to enhance adhesion of the ink receptive coating thereto or increase the gloss level of the finished glossy ink jet receiving paper product.
  • the paper substrate used in the present invention preferably also contains at least one element selected from the group consisting of silicon, aluminum, titanium, potassium, iron, magnesium, sodium and calcium. These elements are important to paper appearance and physical properties. They also sometimes reduce ink migration and dye fading.
  • the gloss of the paper used in the present invention is important. This is because high gloss is required in many ink jet imaging applications, particularly in the areas of graphic art, pre-press proof reading, display and presentation. Further, gloss is also a key factor that affects color gamut.
  • the gloss is the characteristic of the paper surface that causes it to reflect light at a given angle of reflection in excess of the diffuse reflection at that angle.
  • the paper substrate used in the present invention should have gloss greater than about 20, and preferably greater than about 30 as measured at a 60 degree angle.
  • the gloss values are obtained from a Micro Tri-Gloss Meter (BYK-Gardner), according to the procedure described in the product manual.
  • the test procedure for determining gloss more specifically entails the following steps: cut paper sample into a 21,59 cm by 27,94 cm (8.5 inch by 11 inch) size sheet; calibrate the Micro Tri-Gloss meter at 60 degrees using the standard supplied with the unit; place sample on a flat surface and measure the gloss at 60 degrees; repeat the measurement on five samples; and report the average value.
  • the ink receptive coatings utilized to prepare the glossy ink jet receiving papers should not reduce the gloss of the paper substrates utilized.
  • the ink receptive coating utilized should be capable of increasing the gloss of the paper substrate at least 10%.
  • the opacity of the paper substrate used in the invention should be greater than about 70%, and preferably greater than about 80%.
  • the opacity is measured on a BNL-3 Opacimeter (Technidyne Corp.), according to the procedure described in the product manual.
  • the test procedure for determining opacity more specifically entails the following steps: cut paper sample into a 10 cm by 10 cm square; calibrate the opacimeter according to the standard procedure; and measure 5 samples and report the average value.
  • the smoothness of the paper substrate is a property that affects the paper's appearance and surface property.
  • the smoothness is also associated with gloss.
  • the Sheffield smoothness of the paper should be below about 80 Sheffield Units and preferably below about 60 Sheffield Units.
  • the Sheffield smoothness is measured on a Hagerty Smoothness Tester (Model 538, Hagerty Technologies, Inc.), according to the procedure described in the product manual.
  • the test procedure for determining smoothness more specifically entails the following steps: cut sample into a 21,59 cm by 27,94 cm (8.5 inch by 11 inch) size sheet and select Sheffield Units (SU) from the Hagerty Smoothness Tester console; set test zones at 3 centimeters apart; start measurements and report average smoothness values in SU units.
  • the brightness refers to the lightness or overall spectral reflectance of the paper substrate.
  • the brightness of the paper used in this invention should be greater than about 70% and preferably greater than about 80%.
  • the brightness is measured on a Photovolt Model 575 Reflection and Gloss Meter (Seragen Inc.), according to the procedure described in the product manual.
  • the test procedure for determining brightness more specifically entails the following steps: cut paper sample into a 10 cm by 10 cm square; calibrate the meter by placing a standard white enamel plaque over the search unit and adjust the sensitivity knobs to set the meter to standard value; place the sample to be measured over the search unit and back it with the white standard enamel plaque; read the brightness values; and repeat with five samples and report average value.
  • the ink receptive coating layers present in the glossy ink jet receiving paper of the present invention are coated on a surface of the paper substrate and can exist as either a single layer, or alternatively they may be a multi-layer coating structure. However, it is required that at least one ink receptive coating containing one or more water-soluble components in a total amount of about 4 to about 100 weight %, based on the total weight of solids in the coating, must be present in the provided ink jet recording receiving papers encompassed hereby.
  • the water soluble components are preferably present in the ink-receptive coating in a total amount of about 20 to about 100 weight %, and most preferably in a total amount of about 30 to about 100 weight %, based on the total weight of solids in the coating.
  • the ink receptive coatings used in the glossy ink jet receiving papers of the present invention contain at least one water-soluble component and may contain more than one if so desired.
  • the chosen water-soluble components are preferably soluble in an amount of about at least 1 wt%, and more preferably about at least 3 wt%, in water at a temperature in the range of about 5°C to about 100°C.
  • the coating materials used to prepare the ink receptive coatings have to be carefully selected so that the resulting ink jet receiving sheet has a gloss of about 50 or above as measured at a 60 degree angle, a Sheffield smoothness of less than about 300 Sheffield units as measured on the surface carrying the ink receptive coating, an opacity of greater than about 70% as measured on a surface of the paper coated with the ink receptive coating, and a brightness of greater than about 70% as measured on a surface of the paper coated with the ink receptive coating.
  • water-soluble components which may be used in such coatings are poly(vinyl alcohol), poly(vinyl pyrrolidone), poly(2-ethyl-2-oxazoline), polyacrylamide, gelatins, poly(vinyl acetate), poly(ethylene glycol), poly(ethylene oxide), cellulose esters, proteins, alginates, poly(acrylic acid), water-soluble gums, and mixtures thereof.
  • the water-soluble component may be a component of a homopolymer, a copolymer or a polymer blend.
  • the ink receptive coating should be soluble or swellable in the ink to be used for the intended application.
  • soluble when used in this context means that the coating is soluble in the ink in an amount of about at least 1% on a wt/wt basis.
  • swellable when used in this context means the coating increases in volume in the ink as a function of time before reaching a saturated state.
  • inorganic and/or organic particulates may be incorporated in the coating layer to provide proper handling properties, increase brightness, provide high surface gloss to the ink receiving paper, as well as mixtures of these properties.
  • Another function of the particulates is to prevent sheet to sheet ink transfer when imaged sheets are stacked for long term storage and in such instances the particulates can be incorporated in either the ink receiving side or backing side of the prepared glossy ink jet receiving media.
  • inorganic particulates which may be used in the glossy ink jet receiving media are silica, titanium oxide, alumina, glass beads, barium sulfate, diatomaceous earth and zinc oxide.
  • organic particulates which may be used include poly(methyl methacrylate), polyethylene, polypropylene, starch, polytetrafluoroethylene and polystyrene.
  • the coat weight of the coating should be well controlled.
  • the coat weight of the ink receiving coating should be within the range of about 1g/m 2 to about 30 g/m 2 , and preferably from about 2 g/m 2 to about 20 g/m 2 .
  • the side of the substrate which does not bear the ink receptive coating may need a backing material in order to reduce electrostatic charge and to reduce sheet-to-sheet friction and sticking.
  • the backing may either be a polymeric coating or polymeric film.
  • any of a number of coating methods may be employed to coat the coating composition onto the paper base, such as roller coating, wire-bar coating, dip coating, extrusion coating, air knife coating, curtain coating, slide coating, blade coating, doctor coating, or gravure coating. Such techniques are well know in the art.
  • additives may be employed in the coatings of both sides of the paper.
  • These additives include surface active agents which control wetting or spreading action of the coatings, antistatic agents, suspending agents, and compounds with acidic groups to control the pH, among other properties, of the coated paper.
