Definitions

  • the invention relates to a method for manufacturing recording paper, particularly ink-jet recording paper.
  • Such recording papers generally comprise a substrate most commonly made of papermaking pulp, a so-called base paper, and thereon an absorption layer.
  • the purpose of the absorption layer is to receive the colour in the colour jet (ink jet) of the ink-jet printer and to absorb the liquid in the printing ink so that the colorants in the printing ink remain on the surface of the recording paper, forming a sharp image.
  • the development of recording papers has concentrated in particular on developing the materials and methods of spreading the absorption layer.
  • the layer on the substrate may be called an absorption layer, it may often comprise of two or more layers, which may differ with regard to composition and/or the spreading phase and which have different purposes in the recording paper.
  • the absorption layer is such that it rapidly absorbs the liquid in the printing ink in the vertical direction (z direction) but does not spread the liquid in the x/y direction, that is, in the direction of the recording paper's image plane.
  • a long known method of manufacturing recording paper is to spread, by some known method of coating, an aqueous solution or dispersion of the absorption material on the substrate, which, after drying, forms the absorption layer on the substrate.
  • a recording paper manufactured using this method is described in the publication EP-650850, among others. It has been attempted to avoid drying by selecting the material of the absorption layer so that it may be applied by the extrusion coating technique, whereby, instead of removing water, it is sufficient to allow the layer spread in a molten state to cool down.
  • the basic raw material of the absorption layer is a polymer spread in a molten state, which, on solidifying, forms the absorption layer.
  • the receiving layer It is required of the receiving layer that the colorants of the printing ink can be bonded to it permanently and that it does not change them to such an extent that their tones change, but, on the other hand, the receiving layer must have good permeability to the liquid medium of the printing ink.
  • the pigments of the surface layer improve the absorption capacity of the surface, compared to binders alone, which, on the other hand, enable better gloss.
  • a recording paper whose surface has a high water absorption capacity as well as high gloss and smoothness would be an optimal solution.
  • EP-826510 and US-6180219 have presented a method whereby particularly the gloss of the recording paper surface can be improved.
  • the methods are characterised by the use of a special film with a smooth surface, whereby the desired properties can be obtained on the surface of the absorption layer of the recording paper.
  • an ink- receiving layer is spread on the film that forms the surface layer in the final recording paper.
  • an absorption layer is spread as a mixture containing binder and pigment, and on top of this layer yet another adhesion layer can be spread.
  • the film is laminated onto the layers that have been spread on the surface with the help of moisture and roll nip pressure.
  • the surface layer originally on the film becomes attached permanently to the layer on top of the substrate, for instance the adhesion layer that is uppermost.
  • the film detaches along the interface of the surface layer and the film, and that surface of the surface layer that was against the surface of the film forms the smooth, glossy surface of the recording paper.
  • the surface layer is spread on top of the absorption layer spread on the substrate, and while the surface layer is still wet, a smooth film is placed uppermost in contact with the surface layer and, after drying, detached with the same results as above.
  • a method is also known from US patent 5958168 (example I-3), by which method the surface layer spread on a smooth-surfaced film and paper laminated with polyethylene are pressed together in a calender nip at a temperature of 80°C, whereby the surface layer adheres to the laminated paper, its polyethylene surface, and after the film is detached, a smooth, glossy surface is obtained.
  • particles of synthetic amorphous silica of less than 1 ⁇ m are used.
  • the manufacture of recording paper with a smooth and glossy surface requires several phases.
  • the smooth transfer film provided with a surface layer and the substrate provided with an absorption layer should be made separately in their own processes, after which the substrate and the surface layer are joined together in a different process, usually utilising pressure, moisture and heat together (in the publication US-5958168, only pressure and heat).
  • pigments may be included in order to accelerate the further penetration of the large amount of water in the ink jet.
  • the problem is that the water-soluble polymer applied in a molten state during extrusion forms a thin surface layer with no pigments. In this case, a water- absorbent, swelling polymer remains on the surface of the recording paper.
  • the purpose of the invention is to disclose a novel process of manufacturing recording paper with high gloss and smoothness by a simpler method.
  • a further purpose of the invention is to present a method that is suitable for the industrial manufacture of recording paper as a continuous process.
  • the method according to the invention is mainly characterised by what is presented in the characterising part of the attached patent claim 1.
  • the general principle is to intervene in the forming of the surface of the absorption layer when the outer surface of the absorption layer is, due to the extrusion process, still in a state where it has not solidified, and the organisation of the various components in relation to one another has not yet taken place.
  • the free forming process of the outer surface of the absorption layer is in a way "disturbed".
  • This invention uses the possibilities of shaping the outer surface of the absorption layer applied to the substrate during the extrusion process, by bringing it into contact with, for example, the surface of a smooth transfer film or with an extra layer spread on this surface. Due to the extrusion, the material of the absorption layer is still at such a temperature that its surface topography and structure, especially the organisation of the various components in relation to one another (inert pigment, hydrophilic polymer), can be influenced.
  • the surface of the transfer film can then function so as to form the surface layer of the absorption layer, which is mixed with pigment and spread on the substrate in a hot melt extrusion process, in such a manner that the binding polymer does not cover the pigment particles near the surface, but the surface in this area remains bare, thus improving the ink receiving capacity of the surface.
  • the transfer film prevents the situation where, due to the different surface forces, a coating is formed on the pigment particles by the as yet unsolidified polymer of the absorption layer.
  • the transfer film can also be used to add a separate extra layer, which is formed in a separate process by combining the smooth surface layer of the transfer film (the future surface layer of the recording paper) and the material in the absorption layer while it is still, due to the extrusion process, at a temperature that promotes the adhesion of the surface layer.
  • the smooth surface layer of the transfer film the future surface layer of the recording paper
  • the material in the absorption layer cools down from this temperature, the surface layer adheres permanently to the absorption layer, and compared to the transfer film, with stronger adhesion.
  • the last stage of the process is to detach the transfer film in order to uncover the smooth glossy surface layer of the recording paper.
  • the smooth outer surface of the recording paper is in this process formed by that layer of the surface layer that was, during the spreading, against the surface of the transfer film.
  • the material of the absorption layer is fed during the extrusion process to a point where the transfer film, possibly provided with a surface layer, and the continuous web formed by the substrate are joined together.
  • the molten material of the absorption layer coming out of the extrusion nozzle then remains between the transfer film and the substrate to form a composite web, and the resulting composite web is then passed through cooling, for example, by being in contact with a cooling surface for a certain distance.
  • Pigments can also be introduced from outside by other methods than by a separate transfer film. Pigments can be spread as evenly as possible on a member, which after extrusion, comes into contact with the outer layer of the absorption layer, an example being the surface of a cooling roller.
  • Figure 2 presents the combining of the transfer film, the material of the absorption layer and the substrate
  • Figure 3 presents the last stage of forming the web to manufacture finished recording paper
  • Figure 4 presents in schematic form the forming of the finished recording paper as shown in figures 1-3 and
  • Figure 5 presents in schematic form the forming of the finished recording paper according to another embodiment.
  • the proportion of pigment in the surface is increased by introducing pigment from outside onto the surface of the absorption layer.
  • One possibility for doing this is to use a continuous transfer film.
  • Figure 1 presents a coating station, where a layer 3 of suitable thickness, which in the finished recording paper forms the surface layer, is applied on a transfer film 4 that is preferably made of plastic and is smooth at least on the application side.
  • the thickness of the film is preferably 12-50 ⁇ m, and the surface roughness of the application side of the film, expressed as a normal smoothness value (PPS smoothness), is preferably less than 0.3 ⁇ m, optimally less than 0.04 ⁇ m.
  • PPS smoothness normal smoothness value
  • the transfer film 4 runs through the application roll A, which spreads the surface layer in the form of a dispersion or solution on the smooth surface of the film.
  • the film may be of polyethylene, polypropane, polyester or other plastic material or some other flexible material that can be run through the various stages of the process as a continuous web and, if necessary, wound into a roll.
  • the plastic film may be non-orientated or orientated in a monoaxial or biaxial manner.
  • the above-mentioned film, which is coated with a dispersion or a solution, is then taken to drying.
  • the figure shows the roll coating method, but also other application methods can be used.
  • the surface energy of the transfer film 4 is adjusted, if needed, in order to ensure that the aqueous solution or dispersion spreads evenly when applied, but that the film can be detached successfully from the surface film after drying.
  • the treatment for obtaining a suitable surface energy may be corona treatment.
  • the film may also be treated with primer to make the surface suitable, in which case no pre-treatment is necessary.
  • Figure 2 presents the stage in the extrusion process where the continuous transfer film 4, coated with a surface layer 3, is laminated to a continuous web formed by the substrate 1 by means of the material of the absorption layer, which is fed into the roll nip formed by the guide roll O and the cooling roll J, in such a manner that the surface layer 3 remains on the inner side of the film 4 in the composite web.
  • the transfer film 4 and the substrate 1 are fed continuously between the rolls O and J, where they are laminated together as a result of feeding from extruder E to the point where the transfer film 4 and the substrate 1 meet, a polymer in molten state in the form of a wide material web M, in other words, as a film whose dimensions are determined, among other things, by the nozzle of the extruder E.
  • the transfer film 4 has been wound on a roll after coating and cooling, the substrate 1 and the transfer film 4 are fed to the rolls O and J from separate rolls, but it is also possible that the transfer film 4 is fed continuously from the stage presented in figure 1 through drying to the extrusion stage shown in figure 2.
  • the polymer that is fed in is at a certain temperature, which after lamination promotes the adhesion of the surface layer 3 that is on top of the transfer film 4 to the absorption layer 2, which is formed from the polymer fed in a molten state into the roll nip between the rolls O and J.
  • the transfer film 4 and the web formed by the substrate 1 having between them the solidifying and cooling absorption layer 2 and the surface layer 3 adhering to it pass over the cooling outer surface of the cooling roll J, from which the composite web is guided to further processing with the help of another guide roll O, the transfer film remaining on top of the absorption layer after the cooling roll J.
  • the transfer film 4 is guided to the roll nip by the cooling roll J, and after the nip the cooling of the composite web takes place on the side of the transfer film 4, since this film is against the cooling roll. At this stage the surface of the absorption layer 2 on the transfer film side cools downs faster, and the surface layer 3 adheres to the absorption layer 2.
  • the substrate 1 guided into the roll nip via the guide roll O is left outermost on the cooling roll J, and the cooling on that side is mainly caused by the surrounding air. In this way the layer spread in the extrusion process cools and solidifies between the webs and forms a finished absorption layer 2 attached on top of the substrate 1 , the surface layer 3 being attached to the said absorption layer.
  • Figure 3 presents the formation of the web of finished recording paper.
  • the web coming from extrusion is guided between two rolls T, and around one of these is gathered the "peel-off' transfer film 4, which is detached from the composite web at the final stage.
  • the finished recording paper is obtained, comprising the substrate 1 and the absorption layer 2, and on top of it the surface layer 3 that has received a smooth and glossy surface having been against the smooth surface of the transfer film 4.
  • This detachment stage can be implemented with a rewinder or slitter-winder, or before any reel-up that forms a finished roll from the continuously fed web for winding the finished recording paper.
  • the detachment of the film 4 can also be done on a sheeting machine.
  • the transfer film 4 can be kept on the web as long as it is expedient to protect the sensitive surface of the recording paper from the mechanical stress caused by different stages of the process and thus ensure that the surface of the recording paper is finally formed.
  • the detached transfer film 4 can be reused for the application of the surface layer 3 at the stage shown in figure 1.
  • the detached transfer film can also be recycled as a continuous material from its detachment back into the surface layer application stage shown in figure 1 , and when necessary it is pre-treated at that stage to make the surface suitable for the spreading of the material that will form the surface layer 3. In this way the transfer film forms a continuous loop-like material web that passes through application, extrusion and detachment stages.
  • the film extruded between the webs is formed of two or more layers, the material for which can be chosen according, for example, to the kind of material the said layers will come into contact with. It is, for example, possible, in the so-called coextrusion process, to arrange on the side of the substrate 1 a layer that improves the absorption layer's adhesion to the substrate. Such a layer on the side of the substrate 1 may at the same time function as a barrier layer that prevents the water in the ink from being absorbed into the substrate 1. This is advantageous especially if the substrate used is a paper made of fibre raw material.
  • the surface layer 3 is normally thinner calculated in terms of g/m 2 than the absorption layer 2 spread in the extrusion process, which absorption layer may comprise more than one layer, as presented above. Also the surface layer 3 may comprise several layers, for example, due to the fact that the layers are applied successively at the stage shown in figure 1 on top of the transfer film. The composition of such layers may be different.
  • the thin surface layer 3 produced with the help of the transfer film 4 differs in its composition from the absorption layer and is designed so as to enable the properties of the outer surface of the recording paper to be made appropriate for ink-jet printing.
  • the surface layer 3 functions as the ink-receiving layer in the finished recording paper.
  • a layer of this kind when it has good smoothness and gloss, will reproduce with good resolution and high colour density, for example, the image formed by the ink remaining on it in the process of colour ink-jet printing.
