Definitions

  • the present invention relates to paper or cardboard based on cellulosic fibers. It relates more particularly to a new paper or cardboard comprising at least one layer allowing or facilitating gravure printing. It also relates to a process for manufacturing these papers or cartons.
  • Paper and cardboard are generally coated (or coated) in order to improve their mechanical properties in particular and / or allow printing.
  • Known coated paper or cardboard has at least one coating layer containing pigments and binders.
  • the most commonly used pigment is a clay, such as kaolin. Possibly other pigments are associated with it, such as calcium carbonate, titanium oxide, hydrargilite, talc, barium sulphate.
  • the pigments are fixed to the paper using binders, for example a styrene-butadiene copolymer, an acrylic polymer, a vinyl acetate polymer, natural binders, starch, proteins, caseins, polyvinyl alcohols, or a mixture of these bodies.
  • the coating layer of known coated paper or cardboard can also comprise dispersing agents which have been used for its manufacture from aqueous compositions.
  • dispersing agents are for example tetrasodium pyrophosphate, sodium hexametaphosphate, low molecular weight polyacrylates, at levels of between 0.2 and 0.5% by weight relative to the pigments.
  • the coating layer may also include agents capable of improving the water retention properties such as carboxymethylcellulose, alginates.
  • coated paper or cardboard must have different depending on the printing method for which they are intended: rotogravure, offset, letterpress printing, flexographic printing, screen printing, etc.
  • the ink In rotogravure, the ink is contained in small cells and its transfer by capillarity on the coated paper or cardboard can only be done if the periphery of each cell is in perfect contact with the latter. It was therefore important to use paper or cardboard coated with excellent smoothness. However, the smoothness obtained by calendering is higher the higher the pressure of the calender. It is however necessary to limit the calendering pressure in order to maintain a layer porosity sufficient for the printability of the coated paper or, in the case of cardboard, so as not to weaken certain physical characteristics or mechanical properties such as the thickness and / or stiffness. Or you have to use a paper or cardboard with a higher grammage of the order of 10 to 20%.
  • the invention proposes a new coated paper or cardboard having an excellent aptitude for gravure printing, at the same time as good mechanical properties, without however being of excessive grammage.
  • the paper or cardboard according to the invention comprises at least one coating layer containing hollow, expanded microspheres, filled with an inert gas that is to say which is not capable of reacting chemically with the walls of the microspheres .
  • Document US-A-3 816 169 discloses a substrate, for example paper made opaque with the aid of a coating layer comprising opacifying microspheres of small diameter, less than 2 ⁇ m, containing pigments such Ti0 2 .
  • the expanded microspheres according to the invention have a diameter of about 25 ⁇ m approximately. These hollow microspheres provide the coating layer with great flexibility or compressibility, much greater than that of conventional layers containing mineral pigments or that described in document US-A-3,816,169. This flexibility allows continuous contact between the coated paper or cardboard and the cells containing the ink during gravure printing, without the need for excellent smoothness.
  • the coating layer can be an outer layer.
  • the surface of the coated paper or cardboard has a high coefficient of friction which can be troublesome during the processing operations by preventing the sliding of the coated sheets.
  • the absorption of inks and varnishes is important, which can alter the freshness and gloss of the print.
  • the coating layer containing the microspheres is a sub-layer which is covered with an external film improving the surface properties of the paper or cardboard, for example sliding, gloss.
  • This outer film is a known layer, for example a conventional coating layer based exclusively on mineral pigments, a film of an organic polymer loaded with pigments or not, or a film of an extruded organic polymer.
  • this outer layer is very thin, so as not to alter the flexibility due to the coating layer containing the microspheres.
  • microspheres used in the composition of the compressible layer are for example hollow microcapsules, the flexible wall of which consists of a polymer capable of softening by heating, such as polyvinylidene chloride, polystyrene, a copolymer based on vinylidene chloride. and acrylonitrile, containing inside an inert gas, for example isobutane, chlorofluorinated hydrocarbons, chlorinated derivatives, carbon dioxide.
  • a polymer capable of softening by heating such as polyvinylidene chloride, polystyrene, a copolymer based on vinylidene chloride. and acrylonitrile, containing inside an inert gas, for example isobutane, chlorofluorinated hydrocarbons, chlorinated derivatives, carbon dioxide.
  • the compressible coating layer containing microspheres can have a calculated average thickness of the order of 2 to 50 ⁇ m and more.
  • the compressible coating layer comprises pigments of which 1 to 100% and preferably 25 to 100% by weight consist of hollow microspheres filled with an inert gas, the other conventional pigments being able to be mineral pigments such as clays such as kaolin, calcium carbonate, titanium oxide, hydrargilite, talc, barium sulphate.
  • the compressible coating layer also comprises at least one binder and possibly other ingredients such as dispersing agents, agents capable of improving the water retention properties, etc.
  • the compressible coating layer has a mass of 1 to 10 g and preferably 2 to 5 g per m 2 of surface.
  • the paper can be coated on one of its faces with two or more coating layers containing microspheres.
  • the paper or cardboard comprises a coating layer or sublayer containing microspheres on each of its faces.
  • the invention also relates to a process for the production of coated paper or cardboard.
  • the paper or cardboard is coated on one or both sides with an aqueous composition containing synthetic polymers in the form of hollow microspheres containing an inert gas, expandable with heat, at least one binder, if necessary other pigments and other conventional ingredients as mentioned above.
  • the coated paper or cardboard is then dried at the softening temperature of the hollow microspheres, generally between 80 ° C and 120 ° C approximately. This drying lasts a few seconds, or more if necessary, and has the effect of causing the microspheres to expand.
  • an aqueous composition is used containing microspheres already expanded beforehand after having undergone a heat treatment.
  • a perfectly uniform and homogeneous layer is obtained which has a much greater flexibility than that of conventional layers based on mineral pigments.
  • the coated paper or cardboard is advantageously covered with an external film and can also undergo a finishing operation such as calendering, brushing or superglazing.
  • the coating process it is possible to use, for example, the air knife, the size press, the Champion coater, the Massey coater, the trailing scraper.
  • Aqueous coating compositions are prepared with the components and in the proportions indicated in Table 1. The amounts are expressed per 100 parts by weight by weight of pigment (microspheres plus mineral pigments).
  • the microspheres consist of hollow capsules made of polyvinylidene chloride or a copolymer of vinylidene chloride and acrylonitrile containing isobutane.
  • the microspheres sold under the name SARAN by the company DOW CHEMICAL or the PVDC microspheres of the Swedish company KEMANORD are used.
  • the expandable microspheres have an average diameter of 5 wm.
  • compositions contain a binder which is a styrene-butadiene latex. They contain a thickener such as the carboxymethyl cellulose designated by the abbreviation CMC in the table. They also contain a lubricating agent such as a stearate. Finally, they contain a dispersant such as a polyacrylate.
  • a binder which is a styrene-butadiene latex. They contain a thickener such as the carboxymethyl cellulose designated by the abbreviation CMC in the table. They also contain a lubricating agent such as a stearate. Finally, they contain a dispersant such as a polyacrylate.
  • the dry extract of the aqueous compositions is generally between 10 and 30% by weight.
  • a 150 g / cm 2 paper consisting of two jets of pulp, namely 100 g of bleached pulp and 50 g of unbleached pulp, is coated on the side of the bleached pulp using the aqueous compositions according to Table 1, prepared beforehand.
  • the coated paper is then dried by a battery of driers at a temperature of 90 ° C for approximately 15 seconds, which has the effect of softening the microspheres and allowing their expansion to an average diameter of the order of 25 ⁇ m approximately then it undergoes a calendering by passage between two cylinders with a diameter of 25 cm exerting a force of 20 kg (196 N) per linear cm.
  • the layer containing microspheres is advantageously coated with an external film, it is possible to equip the radiator grille with a water doctor who regularly distributes, at the time of calendering, an aqueous polyethylene emulsion at a rate of 2 g / m 2 .
  • the paper is then conditioned at a temperature of 23 ° C in an atmosphere at 50% relative humidity.
  • coated papers according to Examples 1 to 14 are examined from the point of view of their aptitude for heliographic printing.
  • a suitable device is the IGT device of the “Voor Graphische Technick tno Amsterdam • institute. After having scraped the excess ink from a hollow engraved wheel, we print dynamically the coated paper to be tested under given pressure (300 N / 3 cm and 600 N / 3 cm) and speed (100 cm / s) conditions.
  • Printing in plain area allows only a qualitative judgment that is difficult to express.
  • the prints in dotted lines and in degraded range show the good printability of the papers according to the invention.
  • Printing in dot lines determines the printability by the number of missing dots; the lower the number of missing dots, the better the impression. On the papers according to Examples 1 to 11, zero missing points are observed. On papers 12, 13 and 14, there are respectively 6, 11 and 12 missing points.
  • Printing in degraded area determines the aptitude for printing by the distance between the start of printing, starting from the strong tone, and the first point of imitation unprinted; the greater the distance, the better the uniformity of the impressions.
