Definitions

  • the present invention relates to a process for producing a coated high-gloss paper having a superior printability.
  • a coated papers having a coated-layer composed of pigment and binder are used as a high grade printing paper, wherein the gloss of the surface of a coated layer is an important factor besides a printability including ink-absorbency, coated-layer strength, etc.
  • the smoothing by a press on the surface of a coated layer causes the destruction of voids in the coated-layer, thereby lowering the ink-absorbency.
  • the use of a large amount of water-soluble or -dispersible polymer, such as polymeric latex, which is used as the binder for pigment increases a coated-layer strength and gloss, but lowers an ink-absorbency owing to the decreased voids in a coated-layer. Accordingly, the gloss and the printability have adverse tendency in this case.
  • the kinds and amounts of pigment and binder, the amount of coating material, the degree of smoothing treatment and the like are determined under the consideration of an appropriate balance of gloss and printability. Therefore, other techniques are required for the production of a high gloss paper having a superior printability.
  • the gloss value of the coated printing paper is generally increased in the following order: slightly coated paper, coated paper, art paper, superart paper and cast-coated paper.
  • "High gloss” of the present invention means a higher gloss value than that of superart papers.
  • "a high gloss paper” means a coated printing paper having a high gloss value than that of superart paper.
  • a method using cast-coater is known as a method for the production of high gloss papers, wherein a wet coated-layer composed of pigment and binder is press-contacted with a cast-drum of mirror finishing and dried under heating. This method has a problem including a remarkably slower production speed compared with conventional art papers, coated papers or slightly coated papers.
  • Japanese Patent Laid-Open Application No.56-68188, Japanese Patent Publication Nos 64-10638 and 64-11758 disclose a method for coating a mixture of pigment and polymeric latex or water-soluble polymer, drying a resultant coated-layer and further treating the coated layer with a heated calender.
  • the polymeric latex having a glass transition temperature of at least 5°C or at least 38°C is selected as the used latex, and the temperature of a heated calender is set at a higher temperature than the glass transition temperature of the used latex.
  • this method selects a latex and calender treatment, it is simplified, superior in productivity, but it has as a defect an insufficient gloss, that is, this method does not provide a higher gloss than that of superart papers, and therefore it does not provide the same gloss as that of cast-coated papers.
  • Japanese Patent Laid-Open Application No.59-22683 comprises coating a combination of at least two polymeric latexes of various minimum film-forming temperatures on an uncoated sheet or on a casted sheet, drying the obtained sheet and optionally smoothing the sheet by a calender.
  • the drying of the combined lateces of various minimum film-forming temperatures causes fine crackings on the surface of the coated paper, thereby resulting in a superior ink-absorbency without impairing the gloss.
  • the important point of the above technique consists in causing fine cracks on the surface of the coated sheet, wherein the special care about the drying conditions must be exercised.
  • the drying conditions must be set so as to completely melt the latex of a lower minimum film-forming temperatuer and, partly melt the latex of a higher minimum film-forming temperature.
  • the drying conditions are easily varied by many factors. Considering industrial application of this technique, it is practically impossible to keep the drying conditions uniform and conatant over an entire production system. Therefore, it is very difficult to maintain the constant stable quality.
  • the primary purpose can be achieved by using a coated printing paper which comprises forming on a substrate a pigment-coated layer and then superposing thereon a surface-layer consisting of thermoplastic polymeric latex of a second-order transition temperature of at least 80°C, wherein the surface-layer is treated by a calender at a less temperature than the second-order transition temperature.
  • the secondary purpose can be achieved by using a process which comprises forming on a substrate a pigment-coated layer, coating thereon a thermoplastic polymeric latex of a second order transition temperture of at least 80°C to prepare a surface-layer, drying the and then treating the surface-layer by a calender at a less temperature than the second-order transition temperature.
  • FIG. 1 shows an electron-microphotograph of the surface of the coated printing paper in Example 1.
  • printing base-materials there are generally used papers, synthetic papers, plastic films, non-woven clothes and the like.
  • papers are employed in the wide range.
  • the paper are classified into pigment-coated papers, such as art paper, coated paper, slightly coated paper, coated white board, etc, and into non-coated papers, such as wood-free paper, wood-containing paper, newsprint paper, glazed paper, supergravure paper, etc.
  • the base-material of the present invention including a coated-layer should be selected from the above base-materials.
  • the substrate of the present invention includes all of the substrate forming thereon a pigment-coated layer, but wood-containing paper and wood-free paper, etc. are suitable for this substrate.
  • the process for forming a pigment-coated layer on an uncoated paper is sufficiently carried out by the conventional process for producing a pigment-coated paper, but the pigment in coating material, the kind of binder, the ratio of bindert to pigment are varied depending upon the desired quality.
  • Two- or one- side coated paper (having a coating weight of 2 - 40 g/m2.side) is used as the pigment coated-paper of the present invention.
  • a thermoplastic polymeric latex is coated on the pigment-coated layer to prepare a surface layer.
  • the pigment-coated layer can be optionally smoothed by means of a super calender, gloss calender and the like.
  • thermoplastic polymeric latex on an uncoated paper (as base-material) provide a good printability, but not high gloss.
  • thermoplastic polymeric latex on a synthetic paper or plastic film (as base-material) provide a worse printability (an insuitable effect) owing to the insufficient dryability.
  • thermoplastic polymeric latex used in the present invention is an emulsion of thermoplastic polymer or copolymer (hereinafter referred to as "polymeric latex") and has a second-order transition temperature of at least 80°C.
  • polymeric latex emulsion of thermoplastic polymer or copolymer
  • shell part should indicate a second-order transition temp-erature of at least 80°C.
  • the polymer-lateces having a second-order transition temperature of at least 80°C are used in the present invention regardless of the monomer species and the production process.
  • preferable monomers include, for example, styrene, derivatives thereof, vinilidene chloride, acrylate or methacrylate.
  • the upper limit of the second-order transition temperature is not otherwise limited, but is substantially determined depending upon the monomer species, and the additives such as plastisizer for producing the polymeric latex. In general, this upper limit is about 130°C.
  • the use of the polymeric latex having a second-order transition temperature below 80°C causes an adhesion to the calender roll in the calender treatment, and it provides a coated paper with insufficient gloss, low surface strength and worse printability.
  • the particle size of latex used for the paper-coating is smaller than that of the latex used for other field like paint. It is an average particle size of 100 - 500 nm. However, it seems that the polymeric latex having an average particle size of less than 100 nm is preferable in the present invention.
  • the polymeric latex of the present invention is coated alone on a pigment coating layer.
  • various additives are added thereto in the range free of harming the purpose of the present invention.
  • These additives are as follows: natural or synthetic coating-binders, fluidity-adjusting agents for the controll of coating suitability, antifoamers, lubricants for the adhesion to calender rolls, coloring agents for the coloration of a coating layer surface, a small amount of pigments, and the like.
  • the above additives may be mixed appropriately to prepare a coating material for a surface-layer.
  • the resultant coating material for the surface-layer is coated on a pigment-coated layer to produce a surface-layer.
  • the coating amount can be suitably adjusted to obtain a desired quality. With the large amount of the coating, the costs are increased, the ink absorbency is reduced, the ink set is insufficient, and the strength of the surface -layer is lowered. Accordingly, the large amount of the coating is disadvantageous. In ordinary cases, it is suitable to use a coating amount of at least 0.1 g/m2, preferably 0.3 - 3 g/m2 on one side of a coated paper.
  • the coating material for the surface-layer is applied by means of a conventional coater used in paper coating, for example, blade coater, roll coater, air-knife coater, bar coater, gravure coater, flexo coater and the like.
  • a conventional coater used in paper coating for example, blade coater, roll coater, air-knife coater, bar coater, gravure coater, flexo coater and the like.
  • the drying after the coating, if the polymeric latex of the present invention is used, requires no specific equipment, and it is carried out by the conventional drying systems used for the production of coating papers.
  • the obtained surface-layer is treated by a calender to prepare a high gloss-layer.
  • the kind of calenders is not otherwise limited, and super-calender and/or gloss-calender used for smoothing a coated paper are generally employed.
  • the calender-treatment, of which the conditions are important, must be made at below the second-order transition temperature of the polymeric latex used for a surface-layer. Any temperature below the second-order transition temperature can be used. However, its temperature is preferably the at least 5°C lower temperature, more preferably the 10°- 30°C lower temperature, than the second-order transition temperature.
  • coated printing paper of the present invention has both superior printability and high gloss.
  • Fig. 1 shows an electron-microscopic photograph of the surface-layer of the coated printing paper used in the present invention.
  • the surface-layer does not consist of an continuously uniform film formed by melting a polymeric latex, but constitutes a structure in which the polymeric latex particles of several ten nano meter are separated from each other.
  • the polymeric latex owing to its high second-order transition temperature of at least 80°C, is fixed under holding the form and size of latex-particles without melting and without forming a continuous film, under the conventional drying conditions and the subsequent calender treatment, which is made below a second-order transition temperature.
  • there are many voids between polymeric latex particles so that the printing inks are filled in the voids and pass through the capillary tubes among the particles. The passed ink reaches the pigment-coated layer, where it is absorbed.
  • the latex holding the form and size of latex-particles without melting as shown in Fig. 1 has no film strength.
  • the glazed surface-layer of the present invention has practically sufficient strength.
  • the reason for the sufficient strength is now unknown, but it is assumed that the polymeric latex having a second-order transition temperature of 80°C has a certain hardness in a calender treatment. Accordingly, the calender treatment after the coating of this latex on the pigment-coated layer causes complicated actions of the properties, such as packing, elasticity, etc.
  • a coating color of a 64 % solid content 70 parts of 1st class kaolin, 30 parts of fine ground calcium carbonate, 13 parts (solid content) of styrene-butadiene copolymeric latex and 5 parts (solid content) of a 35 % aqueous starch solution were mixed to produce a coating color of a 64 % solid content.
  • the coating color was coated on a wood-free base paper of a basis weight of 127 g/m2 in a coating amount of 14 g/m2 side (dry basis) by means of a blade coater with a coating speed of 500 m/min. After drying, a base material of a 5.5 % moisture content for upper-coating (a pigment-coated paper) having a pigment-coated layer was obtained.
  • the resultant coated paper was treated under a nip pressure of 180 kg/cm through two nip of a supercalender consisting of chilled rolls and cotton rolls so as to contact the upper-coated surface with the metal roll.
  • a coated paper having a high gloss was obtained.
  • Examples 1 and 2 were made at chilled roll temperatures of 65°C and 82°C, respectively.
  • an upper-coated paper was treated under a nip pressre of 1000 kg/cm through two nip of a gloss calender consisting of chilled rolls and heat-resistant rolls so as to contact the upper-coated surface with the metal roll.

  • Comparative Example 1 was made at a chilled roll temperature of 120°C, i.e. a higher temperature than a second-order transition temperature of copolymeric latex.
  • Example 2 An upper-coated solution and base paper in Example 2 were used, and supercalendering conditions, including a roll temperature of 82°C, were made in the same manner as in Example 2, wherein one to several time coatings were made by means of a blade coater (manufactured by Kumagaya Riki Co,) to produce a paper having a high gloss.
  • Examples 4, 5 and 6 had upper-coated weights of 0.7 g/m2, 2,8 g/m2 and 5.5 g/m2,respectivity.
  • Examples 7 and 8, and Comparative Example 2 were carried out in the same manner as in Examples 1 - 3, and Comparative Example 1, except for using a 20 % coating solution which contents 80 parts (solid content) of the copolymeric latex (B) having a second-order transition temperature of 85°C, 10 parts (solid content) of polyethylene wax-type lubricant and 10 parts (solid content) of calcium stearate-type lubricant and except for using a coating amount of 1.2 g/m2 side (dry basis). In this manner, upper-coating papers of high gloss were obtained.
  • Examples 7 and 8 were carried out at chilled roll temperatures of 65°C and 82°C, respectively, (lower temperature than a second-order transition temperature of copolymeric latex), and Comparative Example 2 was carried out at a chilled roll temperature of 120°C, a higher temperature than the second-order transition temperature of the copolymeric latex.
  • Comperative Examples 3 and 4 were carried out in the same manner as in Examples 1 and 3, except for using the copolymeric latex having a second-order transition temperature of 72°C and a coating amount of 1.4 g/m2 side (dry basis), wherein high gloss papers were obtained. Comparative Example 3 was made at a chilled roll temperature of 65°C, lower a temperature than the second-order transition temperature. Comparative Example 4 was made at a chilled roll temperature of 95°C, a higher temperature than the second-order transition temperature.
