  • the present invention relates to a method for continuously producing a ultra-thin coating film on a base such as a plastic film.
  • a variety of functions may be given to a base by forming an ultra-thin coating film having the dry thickness of not more than 1 ⁇ m on the base. For example, by applying solid components to a base such as a plastic film to produce a film having the dry thickness of about 0.1 ⁇ m functioning as an anti-reflection film, the surface reflection of the base can be decreased.

  • the vacuum coating method, CVT, and plasma polymerization method include vaporization of the solid components for application to a base. Accordingly, the coating process should be performed in a closed system, and thus coating of a base having a large surface area is difficult and results in low productivity.
  • the dipping method, spin coating method, and Langmuir-Blodgett ' s technique enable the coating in an open system. However, it is difficult with these methods to coat a base having a large surface area. Further, the continuous production is impossible and the productivity is low.

  • the polymers mentioned above are not particularly limited, and may preferably be monopolymers or copolymers of the above-mentioned monofunctional polymerizable monomers.
  • monopolymers may include poly (methyl (meth) acrylate), poly(2-(perfluorooctyl) ethyl (meth) acrylate), poly (diisopropyl fumarate), polyvinyl acetate, polyvinyl propionate, polystyrene, poly( ⁇ -methylstyrene), polyaryl acetate, polydodecyl vinyl ether, polyvinyl methyl ketone, and polyvinyl ethyl ketone.

  • the mixing ratios of such additives may be adjusted for each additive.
  • the liquid components of the coating liquid are not particularly limited, and may be selected taking the solubility or dispersibility of the solid components, wettability in respect to the base, and evaporation during coating into account.
  • Specific examples of the liquid components may include hexane, toluene, xylene, benzotrifluoride, diisopropyl ether, dichloroethane, methyl ethyl ketone, butyl acetate, isopropyl alcohol, and butanol.
  • the base to which the coating liquid is applied is not particularly limited as long as the coating liquid can be applied by gravure coating method, and may be a plastic film or a paper coated with a resin.
  • the plastic film may include films of polyethylene, polypropylene, polymethylpentene, polyethylene terephthalate, polybutyleneterephthalate, polymethyl methacrylate, polystyrene, polycarbonate, triacetyl cellulose, polyurethane, polysulfone, polyether sulfone, polyether ether ketone, and polyvinyl acetate.
  • the method for continuously applying the coating liquid to the base is not particularly limited as long as it is a method employing a gravure roll.
  • a direct system wherein the coating liquid is directly applied to the base with a gravure roll, or an off-set system wherein an off-set roll is disposed between the gravure roll and the base, may be employed.
  • the gravure roll used for application is not particularly limited, but preferably has 10 to 300 mesh per centimeter, and the mesh depth of 5 to 500 ⁇ m.
  • the number of mesh is not more than 300 per centimeter and setting the mesh depth to not less than 5 ⁇ m, the wet thickness of the coating film is prevented from becoming too thin, thereby facilitating the formation of the coating film, and defects of the coating film due to the insufficiency of the coating liquid supply are prevented.
  • the configuration of the cells on the gravure roll surface is not particularly limited, and gravure rolls having cells in the form of pyramids, lattice or slanted lines may be used.
  • the direction of rotation of the gravure roll bay be forward or reverse direction with respect to the direction of application.
  • the ratio of the rotation speed of the gravure roll with respect to the speed of the application to the base is preferably 0.001 to 500. Setting the speed ratio to not less than 0.001 makes it possible to prevent the wet thickness of the coating film from becoming too thin, and to prevent defects of the coating film due to insufficient supply of the coating liquid. Setting the speed ratio to not more than 500 makes it possible to prevent excess supply of the coating liquid to thus prevent formation of a coating liquid pool between the base and the gravure roll or the off-set roll, thereby improving the uniformity of the coating surface and facilitating the evaporation of the liquid components. However, even if the speed ratio is outside the range defined above, acceptable effects of the present invention may be obtained.
  • the thickness of the coating film immediately after the application of the coating liquid to the base i.e. the wet film thickness
  • the thickness of the coating film immediately after the application of the coating liquid to the base is preferably 0.025 to 1000 ⁇ m.
  • the wet film thickness is preferably 0.025 to 1000 ⁇ m.
  • the dry thickness of the coating film to be obtained may be easily adjusted by selecting an appropriate gravure roll and suitably regulating the conditions for the application to thereby adjust the wet thickness of the coating film.
  • the wet film thickness may be calculated indirectly from the thickness of the dried coating film and the change in the volume of the coating liquid.
  • the change in the volume of the coating liquid may be determined by putting the coating liquid in a vessel such as a Schale, and measuring the volumes of the coating liquid before and after drying.
  • the wet film thickness may also be calculated from the amount of the coating liquid used for the application and the coated area.
  • the coating liquid is applied to the base to form a coating film having the dry thickness of 0.005 to 1 ⁇ m.
  • the dry film thickness is the film thickness after the evaporation of the liquid components, or, when a coating liquid containing the solid components including polymerizable monomers is used for the application, after the evaporation of the liquid components and the completion of the polymerization.
  • the dispersion of the dry film thickness is no limitation to the dispersion of the dry film thickness, but it is preferred for producing industrially superior products that the standard deviation of the dry film thickness is within 25 % of the average dry film thickness.
  • the coating film having the dry thickness of 0.005 to 1 ⁇ m may be formed by, for example, drying the wet coating film, i.e. the coating film immediately after the application of the coating liquid.
  • the method for drying the wet coating film is not particularly limited, and may be carried out by spraying a gas such as air or nitrogen to the wet coating film at the room temperature or a higher temperature in a drying furnace.
  • the liquid components may be dried before or simultaneously with the curing by polymerization, whereas when the polymerizable monomers are not contained in the solid components, the liquid components may be dried before the produced coating film is rolled up. Some types of the liquid components used will evaporate immediately after coating, so that the separate drying process may not be required in this case.
  • the method for polymerizing the polymerizable monomers in the applied coating liquid containing the solid component including the polymerizable monomers may suitably be selected from such methods as irradiation with active energy rays such as ultraviolet rays or electron beams or heating, depending on the kind of the polymerizable monomers.
  • the coating liquid of the particular concentration is continuously applied to the base with a gravure roll, a base having a large surface area can be coated, ultra-thin films having the dry thickness of not more than 1 ⁇ m can be produced continuously, and high productivity is achieved. Further, with the method of the present invention, industrially useful ultra-thin films having highly uniform thickness can be produced.
