The present invention relates to a kind of toner compatibility continuous paper, it is applicable to the printer of electrofax mode, can write down and print the image that is equal to mutually, especially, the present invention relates to a kind of system that is adapted at a high speed and supplies with paper continuously, and have the toner compatibility continuous paper of high picture element, high-speed record, runnability excellence and use the image of this continuous paper to form thing.
Prior art
In recent years, the ITization of entire society is development constantly, requires the instantaneous reception and registration of a large amount of digital information, output, and is that the basis makes the part of information variable etc. with the database.On the other hand, its high picture elementization of the printer of electrofax mode, high speed constantly develop, and have carried out the various combinations of choosing in order to tackle the above-mentioned condition people.With these is background, and the printing on demand field is established, and is the printer of the electrofax mode of title with the digital printer, and particularly the output machine of high speed, high picture element constantly goes on the market.
The duplicator of electrofax mode in the past or printer are object with the office, use the good paper of surface treatment in advance page by page.Relative therewith, become possibility in order to make the high speed lettering, developed under wrapped configuration mode to the continuous lettering of paper.A purpose of this system is to use its means of in the past printing as an alternative.Therefore, except vellum, coated paper for printing or coated paper become the use object, but well-knownly are, produce the foaming of expansion shape during with the hot photographic fixing of toner, so the remarkable deterioration of outward appearance.As countermeasure, if reduce fixing temperature, then the fusion of toner becomes insufficient, produces the gloss deficiency, or problem such as fixing strength deficiency.
The reason that produces of bubbling is thought in the hot photographic fixing of toner by supposition, owing at high temperature shine paper sharp, due to the interior moisture of paper expands.The moisture that expands relies on the interior direction of surface or face and spreads and relaxed by the fine pore in the paper, if but form the toner compatibility layer on the surface, then reduce in the place of water loss, easily foaming.As its countermeasure, the spy opens in the flat 5-241366 communique and has proposed on the paper base material of the air permeability with particular range 3～7g/m to be set
2The coating layer recording layer, the inside that this coating layer contains specified quantitative has the organic pigment in space, and air permeability was reached below 4000 seconds.But, if coating weight is 3～7g/m
2, then can not satisfy feel as coated paper, if many organic pigments of use in coating layer in addition, except existence was easy to generate the shortcoming of static etc., only depending on air permeability was below 4000 seconds, can't suppress foaming fully.In addition, the spy opens and has proposed in the flat 11-160906 communique coated paper is flooded the back salvaging in water, and thickness thereafter increases to below the 30 μ m, and internal bond strength is 0.27kJ/m
2More than, and air permeability is below 6000 seconds.Be to avoid the generation of bubbling in the middle low speed copier at center or the printer with cutting paper, but when using at a high speed as continuous papers such as rolling, though can suppress to bubble, image color and glossiness with homogeneous, but, be difficult to satisfy fully the fixing strength and the superfluous internal bond strength of image because folding breaking property reduces.
Summary of the invention
The present invention a little is a purpose to address the above problem, particularly be adapted to use the electronics photographic means, at a high speed and supply with the system of paper continuously, providing a kind of does not produce owing to the hot photographic fixing in high picture element, high-speed record is bubbled, image color and glossiness with homogeneous, the toner compatibility continuous paper (being designated hereinafter simply as paper) of the fixing strength of image and folding breaking property excellence and use its image to form thing.

Preferably, above-mentioned toner compatibility continuous paper is used to toner image and forms system, promptly after forming the toner picture on the toner compatibility continuous paper, forms image with hot photographic fixing mode.In addition, preferably, above-mentioned toner compatibility continuous paper is used to toner image and forms system, from the blanket roller of heating toner is formed image as the mode of transfer printing.
Image of the present invention forms thing, it is characterized in that: use above-mentioned toner compatibility continuous paper, form image by above-mentioned toner image formation system.
The specific embodiment
Inventors of the present invention are in order to address the above problem, to continuous paper under fast state, write down, when particularly writing down video high density, the generation of bubbling during hot photographic fixing has been carried out research with keen determination to the influence of paper rerum natura.In order to carry out the toner photographic fixing at high speed, fixing temperature must sharply be heated to 150～200 ℃, with the toner fusion, makes its close attachment on paper.It is generally acknowledged and carry out so rapid heating, the moisture that is present in paper inside can expand, and produces foaming owing to having destroyed paper layer configuration.Particularly in the many heavy look portions of tone dosage, heating makes toner become membranization, so the minimizing of the minute aperture of moisture diffusion, more is easy to generate foaming.In addition, because the air that is present in the preceding toner particle layer of photographic fixing expands, there is trickle foaming to produce in image portion sometimes.Therefore,,, then produce the undercapacity of toner compatibility layer if fixing temperature is reduced in order to prevent to bubble, with the cohesiveness reduction of paper, or owing to problems such as image color homogeneity after the different fusions of toner kind and the reductions of glossiness homogeneity.
As the reason of bubbling, if the water vapor diffusion in the ply of paper is easy, or have the interlaminar strength that the opposing water vapour causes the ply of paper of expansion at least, then can not produce foaming.The interlaminar strength of this ply of paper is determined by the bond strength between the paper pulp fiber that constitutes it, must wait by kind, conditions of beating, the interpolation medicine that changes paper pulp intensity is improved.The dispersal direction of water vapour is direction and a thickness direction in the face in the ply of paper in the ply of paper, and especially, in the mode with the hot-rolling heating, because thickness direction is by roll nip (roll nip) clamping or by linings such as toners etc., steam is difficult to diffusion.Therefore, the direction diffusion of vapor is easy to situation in the face in ply of paper by causing, be adapted at a high speed and supply with the system of paper continuously with the electronics photographic means, can obtain not producing foaming, the toner compatibility continuous paper of the fixing strength of toner and glossiness excellence in the hot photographic fixing portion of high picture element, high-speed record.
Because the photographic fixing of toner is to make the dissolving of toner resinous principle with hot-rolling or infrared ray heating, and it is adhered on the paper, therefore when special high speed print, the thermal efficiency becomes problem.Therefore, the density of paper is preferably low, is preferably 0.85～1.10g/cm
3If paper density is lower than 0.85g/cm
3, its rigidity of particularly high quantitative paper improves, and when becoming volume state to use, is accompanied by from the volume core closely more, and it is just serious more to curl, and can produce when having printed the sheet spread behind the image curlingly, is disadvantageous sometimes.In addition, if low-densityization in this wise then is necessary to make the press polish treatment conditions to relax significantly, in this case, not only superficiality reduces sometimes, and the heterogeneity that becomes of the image color after the photographic fixing.In addition, if density surpasses 1.10g/cm
3, particularly wait in the winter time when using under the low temperature environment, produce problems such as toner fixing strength deficiency sometimes, be not good therefore.In addition, the deviation of the variations in density of paper on width by fixing strength, the difference of toner fixing conditions make the deviation of image color and glossiness become big, thus preferred density be limited in the change of width ± 10% in.Paper density ash amount, coating layer density, the coating weight, also is subjected to the influence of Papermaking Conditions, coating, post-treatment condition in depending on body paper, therefore will carry out optimization according to application target.
The interpolation, Papermaking Conditions, sizing agent, surface sizing condition, coating layer that the interlaminar strength of paper is subjected to kind, conditions of beating, ash amount, the paper power reinforcing agent of body paper paper pulp with material, coating condition, contain influences such as moisture, rolling condition.Because these conditions exert an influence to the rigidity of paper rerum natura, whiteness, opacity, DIMENSIONAL STABILITY etc., therefore must suitably select above-mentioned condition according to the difference of purpose.In order to suppress to bubble by the above-mentioned condition of selection, preferred interlaminar strength is 600～1000gcm/in
2If interlaminar strength is lower than 600gcm/in
2, then produce foaming during the toner photographic fixing sometimes.In addition, if be higher than 1000gcm/in
2, when then the warpage imperial decree uses, being easy to generate problems such as back side fracture, the crimping of roller volume core becomes seriously, and runnability is exerted an influence, and produces the problem of curling when carrying out post processing on page, is worthless therefore.As preferred paper rerum natura, rigidity is according to quantitative difference, and its scope is also different, is 10～25cm at paper making course (below be also referred to as the MD direction), and whiteness is more than 75%, and opacity is more than 80%.
The air permeability of preferred paper was processed into below 5000 seconds.As previously mentioned, the reason that bubble to produce is relevant with the moisture in the heated paper with situation, and along with the paper gas permeability increases, the vapour pressure reduction alleviates the load of paper interlaminar strength.The control of air permeability is the hydrophily by kind, beating degree, Papermaking Conditions or the paper pulp that uses the control paper pulp fiber in the preparation of body paper, adding the methods such as medicine that suppress excessive aggegation improves gas permeability, but under the coated paper situation, the formation ability of filming of the pigment type of coating layer, particle diameter, shape or the latex that uses as adhesive exerts an influence to it.And then, after forming coating layer, smoothing is carried out on the surface and handled, wish the coating layer that forms to be carried out high smoothing with low-density as far as possible state.Therefore, preferably, by using and, giving papery and gas permeability that conduct is expected with the method for heating and pressure or in order to prolong the time of continuous heating, pressurization etc., choose the calender that is used for pressue device with the method for roll material etc.
Below the present invention is described in more detail.Be used for paper pulp of the present invention and be not particularly limited, can use for example LBKP (wide leaf tree is shone kraft pulp), NBKP (coniferous tree is shone kraft pulp), LBSP (wide leaf tree is shone sulfite cellulose), NBSP chemical pulps such as (coniferous tree are shone sulfite cellulose).The preferred not chloride paper pulp such as ECF paper pulp or TCF paper pulp that use.In addition, the quality deterioration degree of non-wood pulps such as consideration cotton pulp, old paper stock, GP (ground wood pulp), TMP high yield paper pulp such as (hot method mechanical pulps), and the whiteness reduction of coating back is too much, and the consideration color reproduction can separately or mix more than 2 kinds and use.In order to improve the whiteness after the coating, choose above-mentioned paper pulp and be used for paper base material, or use the paper pulp that the blanching step of paper pulp is strengthened, also can in pulp, add fluorescent dye.
In order to improve density, the control surface flatness is improved the coating adaptability, for the opacity after the coating, whiteness etc. being adjusted etc., is used for paper base material of the present invention and can contains filler in addition.As the filler that can here use, the example comprises calcium carbonate classes such as powdered whiting, precipitated calcium carbonate; Silicic acid classes such as kaolin, sintered clay, pyrophyllite, sericite, talcum; Inorganic pigments such as titanium dioxide; Reach compact-types such as Lauxite, styrene, hollow type or connect the pass organic pigment, but be not limited to these materials.
The use level of filler also is not particularly limited, the scope of preferred 3～15 quality %.If the use level of filler is lower than 3 quality %, the refraction of the light that filler produces reduces, so opacity reduces.In addition, if the use level of filler surpasses 15 quality %, then the rigidity of paper reduces, owing to hindered fiber combining in the paper base material ply of paper, interlaminar strength is reduced, and can't obtain the interlaminar strength as the object of the invention, is worthless therefore.
The various medicines such as sizing agent that are used for paper base material of the present invention can interiorly add or outer the interpolation used.The kind of sizing agent comprises that rosin series sizing agent, synthetic sizing agent, Petropols are sizing agents such as sizing agent, neutral sizing agent, and then can be used in combination suitable adhesive such as aluminum sulfate, cationic starch.From printing the conservatory viewpoint of back paper, preferred alkyl ketenes, olefin butyric anhydride are neutral sizing agents such as sizing agent.
In addition, in order to adjust sheet resistance value, can be used alone or as a mixture organic system materials such as inorganic matters such as sodium chloride, potassium chloride, calcium chloride, sodium sulphate, zinc oxide, titanium dioxide, tin oxide, aluminium oxide, magnesia or alkylphosphonic, alkyl sulfate, sulfonate sodium, quaternary ammonium salt.In addition, can also add paper power reinforcing agent, dyestuff, pH adjustment agent etc.Preferred sheet resistance value is to be 1 * 10 under 23 ℃ of Ω, 50%RH environment
9～1 * 10
13In the scope of Ω, make it be in this scope, can be suppressed in the roller paper feeding and produce static by adjustment, this external electricity consumption gas mode with toner when photoreceptor or intermediate transfer body are transferred on the paper, the transfer printing quality improving.
Toner compatibility continuous paper of the present invention can be the pigment application liquid of principal component with pigment and aqueous adhesive by coating on the one side at least of its paper base material, forms the toner compatibility layer.As the coating layer pigment that can here use, can use separately or a plurality of for example compact-types such as mineral pigment such as powdered whiting, precipitated calcium carbonate, titanium dioxide, aluminium hydroxide, satin white, talcum, calcium sulfate, barium sulfate, zinc oxide, magnesia, magnesium carbonate, amorphous silica, cataloid, white carbon, kaolin, sintering kaolin, delaminated kaolins, alumina silicate, sericite, bentonite, montmorillonite, polystyrene resin particulate, Lauxite particulate, hollow type or perforation pass organic system pigment etc. of being used in combination.
The adhesive that is used for coating layer of the present invention can use separately or to mix additive bonding forces such as use and paper base material, pigment more than 2 kinds strong, the water-soluble binder that caking capacity is few, emulsion, latex etc.For example can use polyvinyl alcohol, modified polyvinylalcohol, starch based, gelatin, casein, methylcellulose, hydroxyethylcellulose, the acrylamide and acrylic acid ester copolymer, acrylamide and acrylic acid-metering system acid ter-polymer, the styrene-propene acid resin, isobutene-maleic anhydride resin, water-soluble resins such as carboxymethyl cellulose, acrylic emulsion, vinylacetate class emulsion, the vinylidene chloride emulsion, polyester emulsion, styrene-butadiene latex, acrylonitrile-butadiene latex etc. can be chosen a kind or multiple use according to required quality from these materials.
For the pigment in the 100 parts by mass coating layers usefulness coating, the cooperation ratio of adhesive is preferably the scope of 5～30 parts by mass.If the cooperation ratio of adhesive is lower than 5 parts by mass, owing to a little less than the coating strength, be not good therefore.In addition, if surpass 30 parts by mass, then the space of coating layer is by the adhesive landfill, and gas permeability descends, and the generation increase frequency of foaming also is not good.
In addition, visual whiteness is improved, therefore also can add fluorescent dye owing in coating, add dyestuff or the organic pigment be used to adjust tone.In addition, as the adjustment agent of sheet resistance value, can use be used for base material known those.And then, for the preparation that makes coating becomes easily, also can add various auxiliary agents such as dispersant, defoamer, plasticizer, pH adjustment agent, flow ability modifying agent, curing accelerator, anti-hydrated agent, releasing agent, ultra-violet absorber, fluorescent whitening agent.
The coating weight of toner compatibility layer is counted with 5～20g/m with the solid constituent of single face among the present invention
2Quality be coated with.If coating weight is lower than 5g/m
2, all fibers in paper base material surface can't be applied because coating weight is very few, at the remained on surface of toner compatibility continuous paper concavo-convex between the fiber arranged, distinct image can not be formed, and, enough opacities can't be obtained because pigment is few.In addition, if surpass 20g/m
2, except that the effect of the improvement of photographs was saturated, gas permeability reduced, bubble easily, and be worthless therefore.Low when quantitative, the variable density and the coating weight of paper are closely related especially, for the variable density that makes width in the scope of central value ± 10%, be necessary the change of coating weight is suppressed in the mobility scale of central value ± 10%.The variations in density of this paper is by taking a sample with 10cm * 10cm square on the width that batches, measure weight, the thickness of each square, calculating density.The quantitatively not special regulation of toner compatibility layer continuous paper of the present invention is usually at 50～250g/m
2About scope in.
Coating process as the coating fluid that utilizes in order to form toner compatibility layer of the present invention, for example can use door print roll coating, size press coating etc. to be provided with coating machine in the machine of apparatus for coating, off-machine coaters such as scraper coating, airblade coating, print roll coating, scraper coating, reverse roll coating, gravure roll coating, the coating of curtain formula, mould coating any.
Smoothing after the coating is handled and can be used smoothing treating apparatus such as common supercalender, gloss calender, soft press-polishing machine to carry out.In addition, when in the use machine or machine external apparatus when carrying out suitable treatment, this smoothing handle can be according to the difference of purpose suitable form, pressurization nip number, the pressed temperature of selecting to use pressue device.
The air permeability of the toner compatibility continuous paper of handling through smoothing is preferred below 5000 seconds, more preferably below 3000 seconds.Subsidiary mentioning, if surpass 5000 seconds, the occurrence frequency that bubbles during hot photographic fixing increases, and is not good therefore.In addition, when low-density,, because the deviation of coating weight, can produce density variation above ± 10% situation even the press polish treatment conditions after the toner compatibility layer formed are chosen as at a high speed and zero load condition such as handle down.In this case, the homogeneity of image color and glossiness reduces, and is not good therefore.
