Description

Ink-jet and electrophotographic recording paper
Technical field
The present invention relates to can be used for the ink-jet and the electro-recording paper of ink-vapor recording and two kinds of methods of electrophotographic recording.More specifically, it relates to ink-jet and electrophotographic recording paper, this paper is the recording chart that does not have the so-called common paper type of additional coatings at recording surface, more specifically, on it, has good water tolerance by the image that ink jet recording method writes down with water-soluble ink, and it has good toner transferability and maneuverability aspect the color record that is undertaken by the electrophotographic recording method.
Background technology
According to ink jet recording method, ink is directly injected on the recording chart, because the cost of the method running is low, noise is little, write down color easily, so noticeable.In this recording method, consider from security and printability aspect, use water-soluble ink, and employed recording chart need have following performance in this recording method, be that ink is absorbed on recording chart fast, the inks different when color overlap each other on recording chart, and ink can not flow together, the ink dot that is mapped on the recording chart suitably spreads, the shape approximation of point is just round, and the edge of point is obvious, the density height of point, recording chart has sufficiently high whiteness, to improve the contrast of point.
As the recording chart that is used for ink jet recording method, Jap.P. JP-A-59-35977 and JP-A-1-135682 propose to be exclusively used in the method to satisfy the coated paper of above-mentioned requirements.On the other hand, in monochrome record and commercial color record field, needs cheaply with general purpose recording chart, promptly be generally used for the common paper of electrophotographic recording method.
So far, when the recording chart that is used for the electrophotographic recording instrument is used for ink jet recording method, there is such problem: because they are poor to the absorbability of ink, if use a large amount of inks, ink can flow on paper, even the absorbability to ink is abundant, ink is absorbed along the direction of paper fiber, also can cause ink dot shape thicken (featheriness).
Recently, ink-vapor recording and useful ink-jet and the electrophotographic recording paper of electrophotographic recording are put on market, but the water tolerance problem of the image of unresolved formation still, it is a problem the most serious in the ink jet recording method.
In order to obtain the water tolerance of image in the ink-vapor recording, containing resin cation in the recording chart can make dyestuff water-fast effectively, and this is because due to the anionic site and the reaction between the resin of ink dye.Yet owing to be the existence of electrolytical resin cation, the surface resistivity of recording chart can descend, and causes the transferable performance of the toner in the electrophotographic recording method to descend.For the runnability of recording chart, the decline of surface resistivity is preferable, but this can greatly influence the transferability of toner, especially in the electrophotographic recording method of panchromatic type.
As mentioned above, for the ink-jet of common paper type and the last black paper of electrophotographic recording, do not obtain the water tolerance of ink as yet.The ink-jet and the electrophotographic recording paper that the purpose of this invention is to provide the common paper type, on it, have good water tolerance, and the color record that it is undertaken by the electrophotographic recording method have good toner transferability and runnability by the image that ink jet recording method write down.
The explanation of invention
The inventor is through deep research, ink-jet and electrophotographic recording paper have been made, have excellent water resistance by the image that ink jet recording method write down on this paper, the color record that is undertaken by the electrophotographic recording method has good toner transferability and runnability.
That is, the present invention relates to can be used for the ink-jet and the electrophotographic recording paper of ink-jet and two kinds of methods of electrophotographic recording, it comprises carrier, and the surface resistivity of this recording chart is 1.0 * 10 9-9.9 * 10 13Ω, carrier contain the gram/rice with 0.5-2.0 2The bonding resin cation on it of dried adhesive capacity.
The cation equivalent number of the resin cation of being measured by the colloidal titration method is preferably 3-8 milliequivalent/gram.
Carrier preferably contains neutral rosin sizing agent or as the alkenyl succinic anhydride of internal sizing agent.
In addition, carrier can contain secondary stock.
The preferred forms of invention
Describe ink jet recording paper of the present invention below in detail.
In order to improve water tolerance by the formed image of aqueous ink that contains the direct dyes that is useful on ink jet recording method or acid dyes, obviously, be effective by reacting the fixing of dye and the water-fast processing that are produced between the anionic site of dyestuff and the cationic materials.
Therefore, in ink-jet and electrophotographic recording paper, also attempt water tolerance by the image that adds resin cation acquisition ink-vapor recording.Yet, when a large amount of resin cations is contained in the recording chart, under situation, can cause that toner descends to the transferable performance of recording chart, causes such problem: for example form blank spot and density of image decline in the image by electrophotographic recording method record color.
Cause to above-mentioned phenomenon is studied, and found that: owing to comprise the electrolytical resin cation of a large amount of conducts, the surface resistivity of recording chart reduces, and causes toner to descend to the transferability on recording chart surface.This phenomenon is especially remarkable in the electrophotographic recording of panchromatic type, and it is very little that this effect shifts color toner to first, but second and the transferability of follow-up toner descend greatly.Someone thinks that a reason of this phenomenon is: if the surface resistivity of recording chart is too small, the first transfer toner just discharges electric charge on recording chart so, the grievous injury chargeability, and follow-up toner just descends to the transferability of recording chart.
The inventor has carried out deep research to the problems referred to above, found that: when the dried adhesive capacity of resin cation is a 0.5-2.0 gram/rice 2, can obtain the gratifying water tolerance of ink-vapor recording ink inside, when surface resistivity is 1.0 * 10 9-9.9 * 10 13During Ω, can obtain toner transferability and the good recording chart of runnability in electrophotographic recording.
If the dried adhesive capacity of resin cation is lower than 0.5 gram/rice 2, can not obtain enough water tolerance of ink, and if it be higher than 2.0 gram/rice 2, the water tolerance of ink is enough, but surface resistivity is lower than 1.0 * 10 9Ω causes that the transferability of toner descends.
Surface resistivity among the present invention (unit: Ω) calculate according to the calculating formula of JIS K6911, particularly, can be by adopting 4329A type high resistance instrument and 16008A type resistivity element, obtaining according to (making) measurements and calculations under the electrification time condition of instrument instructions in the environment of 20 ℃ and 65%RH, by Yokogawa Hewlett-Packard Co. at 30 seconds.
Be used for resin cation of the present invention and be with direct dyes that is contained in aqueous ink or acid dyes in reactions such as sulfonic acid group, carboxyl, amino generate the primary-tertiary amine of insoluble salt or monomer, oligomer or the polymkeric substance of quaternary amine; Wherein preferred oligomer and polymkeric substance.Its concrete example dimethyl amine chloropropylene oxide condensed polymer, acrylamide diallylamine multipolymer, polyvinylamine multipolymer, dicyandiamide, chlorination dimethyldiallylammonium etc.Resin cation is not limited to these examples.
In addition, in the present invention, according to colloidal titration method (adopting the polyvinyl glazier's salt, toluidine blue), the cation equivalent of resin cation is preferably 3-8 milliequivalent/gram.When cation equivalent is in this scope, can obtain the gratifying result that dry adhesive capacity is positioned at above-mentioned scope.When measuring cation equivalent by the colloidal titration method, resin cation is 0.1% with distilled water diluting to solids content, does not regulate the pH value.
The surface resistivity of recording chart is 1.0 * 10 among the present invention 9-9.9 * 10 13Ω, preferred 1.0 * 10 10-9.9 * 10 13Ω.If surface resistivity is lower than 1.0 * 10 9, chargeability increases, and the transferability of toner descends thus; If it is higher than 9.9 * 10 13, chargeability increases, and cause the dispersion of toner, or the runnability of recording chart is undesirable.

By The above results as seen, by with cation equivalent being the 0.5-2.0 gram/rice of 3-8 milliequivalent/gram (measuring) by the colloidal titration method 2(dried adhesive capacity) resin cation is adhered on the carrier, can obtain the recording chart that the visual water tolerance in the ink-vapor recording increases, by giving recording chart 1.0 * 10 9-9.9 * 10 13Ω, preferred 1.0 * 10 10-9.9 * 10 13The surface resistivity of Ω, but the recording chart that the toner transferability of full-colour image is good and runnability is satisfied in the electron gain film recording.
When AKD sizing agent during as the internal sizing agent in the carrier, to compare with using neutral rosin sizing agent or ASA sizing agent, runnability descends a little.Someone thinks that this is because the skin-friction coefficient of recording chart descends, due to recording chart is easy to slide.In addition, when secondary stock is used as carrier, can recognize it to not influence of performance, and all performances are all good.
If the dried adhesive capacity of resin cation is lower than 0.5 gram/rice 2, the water tolerance of image is not enough in the ink-vapor recording, if it is higher than 2.0 gram/rice 2, the water tolerance of image is enough in the ink-vapor recording, but is lower than 1.0 * 10 owing to surface resistivity becomes 9, the toner transferability of full-colour image descends in the electrophotographic recording so.In addition, can find out, if surface resistivity is higher than 9.9 * 10 13, runnability descends.
Ink-vapor recording of the present invention and electrophotographic recording common paper, visual having excellent water-resistance in ink-vapor recording, and also because the dried adhesive capacity of resin cation is a 0.5-2.0 gram/rice 2, surface resistivity is 1.0 * 10 9-9.9 * 10 13Ω is so have good toner transferability and good runnability in electrophotographic recording.
