Definitions
- the present invention relates to an electrophotographic recording material.
- Electrophotographic recording is applied to various fields such as copying machines, terminal printouts, facsimiles, and small number of copies.
- the progress of the output device is also remarkable, the printing speed is improved, not to mention full color, it achieves high definition by improving the toner, the color reproducibility is greatly improved, and it is used for various applications from document output to photo output It has come to be.
- the dry electrophotographic system is a system represented by a copying machine or the like, and a solid powder toner made of a pigment and a synthetic resin is used as a toner for forming an image.
- toner is adsorbed to an electrostatic image on a photoreceptor roll generated by corona charging, the toner is transferred to a recording material, and the transferred recording material is heated by a fixing roll to fix the toner.
- This is a method for forming an image.
- there is a limit to the miniaturization of the toner and it is difficult to obtain high resolution.
- the toner since the toner is dispersed in the liquid, the scattering of the powder is not a problem, and the toner can be reduced to 1/10 or less compared to the dry electrophotographic method.
- This method is suitable for photographic output because the dots forming the portion can be made fine, and since a pigment can be used as a coloring material, there is no problem of weather resistance, and further, no difference in gloss of the image is caused.
- the wet electrophotographic image forming method proceeds by the toner adsorbing to the electrostatic image on the photoreceptor roll and transferring the toner to the blanket roll using potential repulsion in the same manner as the dry electrophotographic method.
- the surface of the blanket roll is made of a material with low interface free energy such as silicon rubber.
- the toner is transferred from the blanket roll to the recording material, and the blanket roll is heated, so that the toner becomes molten and becomes the recording material.
- This is a method for fixing and forming an image.
- the blanket roll, the recording material, or the wet toner is required to have an ability of transferring the wet toner from the blanket roll to the recording material, and so-called toner transferability is important.
- the toner particles are not transferred sufficiently to the recording material, resulting in insufficient image reproduction, or the toner fixing strength transferred from the blanket roll to the recording material is weak, and the toner is detached from the recording surface. Problems may occur. Therefore, as a means for sufficiently transferring the toner to the recording material and obtaining a high toner fixing strength, there is a generally known method called “sapphire treatment”. Such a method has a drawback that a yellow substance is generated in a relatively short time, and a phenomenon of yellowing of a white background, called yellowing of a white paper, occurs and the color development of the image fluctuates.
- the recording material is a thermoplastic resin-coated paper or polymer film in which a paper base material mainly composed of natural pulp is coated with a resin capable of forming a film.
- a thermoplastic resin-coated paper or a polymer film cannot provide sufficient toner fixing, and a configuration in which a toner receiving layer is provided has been proposed.
- an electrophotographic recording material has been proposed in which a specific polypropylene resin layer is provided on both sides of a paper substrate and a toner receiving layer is provided thereon (see, for example, Patent Document 1).
- an electrophotographic recording material having a toner receiving layer containing a resin having a glass transition point defined on a polymer film, a low-resistance treatment agent, and organic polymer fine particles has been proposed (for example, see Patent Document 2).
- An electrophotographic recording material has been proposed in which an antistatic agent is added to the toner receiving layer in order to prevent double feeding of the recording material due to static electricity charged on the recording material (see, for example, Patent Document 3).
- thermoplastic resin-coated paper used as a support An electrophotographic recording material in which an antistatic agent is added to a thermoplastic resin-coated paper used as a support has been proposed in order to prevent double feeding of the recording material due to static electricity charged on the recording material (see, for example, Patent Document 4).
- the toner receiving layer as described in Patent Document 1 or Patent Document 2 is still insufficient in terms of toner fixing in the wet electrophotographic system. Further, these electrophotographic recording materials cannot prevent double feeding of the recording material due to static electricity charged on the recording material.
- the electrophotographic recording material disclosed in Patent Document 3 can prevent double feeding of the recording material due to static electricity charged on the recording material, but the antistatic agent wets the surface of the toner receiving layer, and so-called stickiness occurs. As a result, problems such as easy fingerprint attachment or scratches occur.
- the electrophotographic recording material disclosed in Patent Document 4 can prevent double feeding of the recording material due to static electricity charged to the recording material, but the antistatic agent and the thermoplastic resin of the thermoplastic resin-coated paper are uniformly formed. They are not mixed, and the mixing unevenness affects the toner recording surface and has the disadvantage that image unevenness occurs.
- An object of the present invention is to provide an electrophotographic recording material that has resistance to yellowing of blank paper, has excellent toner fixing strength after printing, and can prevent double feeding of the recording material due to static electricity charged on the recording material. That is.

- an electrophotographic recording material of the present invention yellowing of the recording material is suppressed, and the recording material is excellent in toner fixing strength after printing in the electrophotographic system, and further in the wet electrophotographic system, and the recording material is charged by static electricity. It becomes possible to prevent double feeding of materials.
- the addition ratio of the surfactant having an alkyl betaine structure or a fatty acid amidopropyl betaine structure in the toner receiving layer is 0.3% by mass relative to the content of the ionomer resin. ⁇ 8% by mass.
- the addition ratio of the surfactant is within the above range, the electrophotographic recording material can more stably prevent double feeding and is further excellent in toner fixing strength.
- a toner dispersion in which toner particles are dispersed in a liquid is used as a wet toner.
- the sapphire treatment that has been used as a conventional technique for recording materials for wet electrophotography is to apply an organic component such as cationic ethyleneimine to the surface of the recording material in order to increase the toner fixing strength, and anionic
- the processing method is based on the principle of fixing the toner dispersion.
- the sapphire treatment the reactivity of the cationic organic component used is high, so that it reacts with a coexisting substance, causing a problem that yellowing of a blank paper and discoloration of a printed portion occur after recording an image.
- the toner receiving layer contains at least an ionomer resin.
- the toner receiving layer contains at least a surfactant having an alkylbetaine structure or a fatty acid amidopropylbetaine structure in addition to the ionomer resin.

Abstract
Description
特許文献3に開示されている電子写真記録材料では、記録材料に帯電した静電気による記録材料の重送を防ぐことはできるものの、帯電防止剤がトナー受理層の表面を湿潤し、所謂ベタつきが発生して指紋が付着し易くなる、または傷が付き易くなるなどの不具合が生じる。
特許文献4に開示されている電子写真記録材料では、記録材料に帯電した静電気による記録材料の重送を防ぐことはできるものの、帯電防止剤と熱可塑性樹脂被覆紙の熱可塑性樹脂とは均一に混合されることはなく、混合ムラがトナー記録面に影響を及ぼし、画像ムラが発生する欠点を有する。
