Abstract
An organic electrophotographic photosensitive material highly resistant to stress cracks, solvent cracks and wear, and having markedly improved durability is obtained by incorporating in a binder resin of a charge transport layer of a laminate type photosensitive material a polycarbonate resin prepared using as a starting material a bisphenol compound consisting essentially of a bisphenol compound of the following structural formula (I).
Description
The present invention relates to electronic photographic photosensitive material, more particularly, relate to a kind of containing at the electrophotographic photosensitive material of electric charge migrating layer as the specific polycarbonate resin of adhesive resin.
Electronic Photographing Technology can instantaneous acquisition high-quality image, thereby in recent years not only in the duplicating machine field, and found purposes widely in various printer field.The core of Electronic Photographing Technology is as the electronic photographic photosensitive material that becomes image component.They comprise the conventional inorganic photochromics with photosensitive layer, and this photosensitive layer comprises inorganic photoconductive material, as selenium, selenium-arsenic alloy, cadmium sulfide and zinc paste.Developed the organic photosensitive material that has the photosensitive layer that comprises organic photoconductive material recently, and, because of its many advantages, as pollution-free, easily film forming, and high yield, and the easy acquisition of many materials etc., and development more and more widely.Well-known organic photosensitive material is the so-called single-layer type photochromics that has the dispersion of photosensitive layer, this photosensitive layer comprises the superfine broken organic photoconductive material that is dispersed in the adhesive resin, with the so-called laminated-type photochromics that has photosensitive layer, this photosensitive layer comprises charge generation layer and electric charge migrating layer laminated together.
Fig. 1 shows preceding a kind of single-layer type photochromics that has photoconductive base material 1 and photosensitive layer 20, and photosensitive layer 20 comprises the superfine broken organic photosensitive material that is dispersed in the adhesive resin 5.
The laminated-type photochromics of a kind of photosensitive layer 21 that comprises photoconductive base material 1 and provide in the above in back is provided Fig. 2, the lower floor of photosensitive layer is the charge generation layer 4 that contains as the charge generation material 3 of key component, and its upper strata is the electric charge migrating layer 6 that contains charge transporting material.
The back outstanding advantage of a kind of laminated-type photochromics shows: by on function their photosensitive layer being divided into a kind of charge generation layer and a kind of electric charge migrating layer that is used for moving the charge carrier that is produced that receives light and produce charge carrier, from be most appropriate to their (each layers) separately materials with function make these the layer, and their (each layers) are combined into laminated product, make them have hypersensitivity; They can allow extensively to select material and have high security; Can apply formation with their each layer, thereby output is high and with low cost.Therefore, they very likely become the main flow of photochromics, and their commercial application prospect is wide.
Electronic photographic photosensitive material requires to have electrical property, mechanical property and the optical property that is suitable for used electronic camera technology.Photochromics uses especially repeatedly, require to by corona discharge, toner development, transfer on the paper or the electronics or the mechanical force of cleaning the top layer that directly affacts them has permanance.That is to say, their require to the decline of characteristic such as susceptibility reduce, charge capacity reduces, and the rest potential that causes because of the ozone that produces in the corona discharge process raises all inhibited; And it is inhibited to the photochromics surface abrasion or the scar that cause by the friction in its development, transfer or the cleaning process.
The surface of organic photosensitive material is the layer of being made up of resin basically, thereby material very easily is subjected to the influence of resin properties.The resin that is used for satisfying the desired characteristic of superficial layer is the polycarbonate resin that contains as the bisphenol-A of skeletal substance.Hereinafter, polycarbonate resin is meant the bisphenol A polycarbonate resin.
Yet the bisphenol A polycarbonate resin can not satisfy desired all characteristics of resin of photochromics fully, problem below they exist:
(1) their dissolubility is too poor, only in some halogenated aliphatic hydrocarbon, as showing solubility property preferably in methylene chloride and 1, the 2-ethylene dichloride.These halogenated aliphatic hydro carbons have low boiling.When the coating solution that is made by these solvents was used for making photochromics, coating surface trended towards bleaching.The technology controlling and process of solids is also relatively required great effort in the coating solution.
(2) they are dissolved in some solvents except that halogenated aliphatic hydrocarbon, as tetrahydrofuran, dioxan and cyclohexane, or the potpourri of these solvents.As time goes on gained solution make bad stability, and this can be found out by their gelatification in several days, and be not suitable for producing in enormous quantities.
(3) only contain bisphenol-A or bisphenol-a derivative and be subject to solvolysis as the polycarbonate resin of main skeletal substance.
The cyclohexylidene that contains large volume by use has solved problem (1) and (2) about steady dissolution as the polycarbonate Z resin of the structural unit of polymkeric substance.Yet as pointed in problem (3), when the solution of polycarbonate Z resin and polycarbonate A resin formed film by casting, they significantly reduced on volume, and may stay stress in film.Therefore, there is the shortcoming that is subject to stress cracking in they.In order to solve this shortcoming, Japanese Patent Application Publication No.62040/1986 has disclosed a kind of method that reduces stress cracking by mixed polycarbonate A resin and polycarbonate Z resin.Equally, Japanese Patent Application Publication No.62039/1986 discloses a kind of by allowing bisphenol-A and bisphenol Z copolymerization reduce the method for stress cracking.But these methods do not have the counter stress cracking that enough permanance are provided.
In recent years, require in the organic photosensitive material, to improve susceptibility.For catering to this requirement, usually use low molecular weight compound relatively in large quantities, as charge transporting material.In the film forming process, or in the long term storage process, this type of lower-molecular-weight component precipitation causes to be separated.
In addition, the actual at present laminated-type organic photosensitive material that uses especially is inferior to inorganic photochromics aspect permanance.A factor of decision permanance is a physical property.Yet also there is following defective in laminated-type organic photosensitive material: because of the load in the reality use, as use toner development, rub their easy to wear or galled spotss with the paper friction with cleaning element.This drawbacks limit their printing tolerance.
The present invention finishes for overcoming above-mentioned shortcoming.The object of the present invention is to provide a kind of height stress crack resistant, solvent to disperse and wearing and tearing, and has the organic photosensitive material that improves permanance significantly, mode is to a kind of resin of electric charge migrating layer introducing as adhesive resin, this kind resin has the solvent soluble of height, with the charge transporting material highly compatible, easily form satisfied film, and have high-wearing feature.Can reach this purpose by the electronic photographic photosensitive material that on conductive substrates, has charge generation layer and electric charge migrating layer, these layers are made up of organic substance basically, and (polycarbonate resin refers to polycarbonate resin of the present invention hereinafter wherein to use the bisphenol compound of being made up of the bisphenol compound of following structural formula (I) basically as initiation material to make polycarbonate resin.), it is incorporated in the electric charge migrating layer as adhesive resin.
