- an organic solvent e.g. benzene, acetone, methylene-chloride, ethyleneglycol monomethylether
- the amino-phenyl substituted oxazole compounds utilized according to the present invention may be used in admixture with at least one other organic photoconductive substance.
- the photoconductive insulating layers may include at least one water-insoluble organic resin in association with the oxazole compound.
- Natural and synthetic resins e.g. balsam resins, phenol resins modified with colophony, and other resins of which colophony constitutes the major part, coumarone resins and indene resins, and the substances covered by the collective term synthetic lacquer resins, which according to the Kunststofftaschenbuch (Plastics Pocket Book) published by Saechtling-Zebrowski (11th edition, Kunststoff, 1955, page 212 forward) include:
- polymers such as the polyvinyl chlorides, polyvinyl acetates, polyvinyl acetals, polyvinyl ethers, polyacrylic and polyrnethacrylic esters, as also polystyrene and isobutylene;
- polycondensates e.g. polyesters, such as phthalate resins, alkyd resins, maleinate resins, maleic acidcolophony-mixed esters of higher alcohols, pheno1- formaldehyde resins, particularly colophony-modified phenol-formaldehyde condensates, urea-formaldehyde resins, melamine-formaldehyde condensates, aldehyde resins, ketone resins of which particular mention is to be made of AW 2 resins of the firm 12 Badische Anilinund Soda-Fabrik, xylene formaldehyde resins and polyamides; and
- polyadducts such as polyurethanes.
- the proportion of resin to photo-conductivesubstance may vary very greatly.
- the use of mixtures of approximately equal parts of resin and oxazole compounds has been found to be advantageous. If the mixtures used consist of about equal parts of resin and oxazole compound, the solutions after coating and drying in most cases form clear layers which can be regarded as solid solutions.
- the base materials used as supports for the photoconductive layer may be any that satisfy the requirements of xerography, e.g., metal or glass plates, paper or plates or foils made of electrically conductive resins, or plastic resin films.
- the electroconductivity of the base material must be higher than the electroconductivity of the photo-conductive insulating layer, preferably higher than 10 ohrn/cm. If paper is to be used as a support for the photo-conductive layer, pretreatment of the paper against penetration of the coating solution is advisable, e.g.
- Aqueous dispersions of said substances suitable for the pretreatment of the paper surface may also be used.
- solutions of the compounds of the diphenyland triphenyl-oxazole series to be used as provided by the invention, with or without the resins, are applied to the supports in the usual manner, for example by spraying, by brushing, by direct application by means of rollers, etc., and then dried so as to produce a thin coherent homogeneous photo-conductive layer adhering on the electro-conductive support.
- the photo-conductive layers are generally charged positively or negatively by means of a corona discharge.
- the thus obtained charged photo-conductive layers have a light-sensitivity generally lying within the range of the long-wave 'U.V. light of about 3600 to 4200 A.U. Even very short exposure under a master to a high pressure mercury lamp will give good images.
- the layers corresponding to the invention have, even when charged, very little sensitivity to the visible range of the spectrum.
- the further discovery has been made that the spectral sensitivity of the photoconductive layer can be extended by means of sensitizers into Triarylmethane dyestuffs, such as Brilliant green (No. 7
- Xanthene dyestuffs namely rhodamines, such as Rhodamine B (No. 864, page 365), Rhodamine 6 G (No. 866, page 366), Rhodamine G ex-tra (No. 865, page 366), Sulfo-rhodamine B (No. 863, page 364), and True acid eosin G (No. 870, page 368),also phthaleins, such as Eosin S (No. 883, page 375), Eosin A (No. 881, page 374), Erythrosin (No. 886, page 376), Phloxin (No. 890, page 378), Rose Bengal (No. 889, page 378), and Fluorescein (No. 880, page 373);

- Thiazine dyestuffs such as Methylene blue (No. 1038, p
- Acridine dyestuffs such as Acridine yellow (No. 901, page 383), Acridine orange (No. 908, page 387), and Trypaflavine (No. 906, page 386);
- the photoconductive layer has been provided with an electrostatic charge by means of, for example, a corona discharge with a charging apparatus maintained at 6000-7000 volts
- the support e.g. paper or aluminum foil or plastic film
- the sensitized layer is exposed to light through amasteror by episcopic or diascopic projection to form an electrostatic pattern corresponding to the master applied by causing to leak away the electrostatic charge on the areas of the photoconductive layer struck by light and then developing the electrostatic pattern by dusting over in known manner with a resin powder colored with carbon black.
- the image that now becomes visible by the adherent particles of the resin powder can easily be wiped off. It therefore has to be fixed; it can, for example, be heated briefly, by means of an infra-red 'radiator, to about 120 C., or to whatever the baking temperature of the developer powder used may be.
- the temperature required is less if the heat treatment is carried out in the presence of vapors of solvents such as trichloroethylene, carbon tetra-chloride or ethyl alcohol.
- the electrostatic pattern may also be developed by means i of a liquid developer consisting of a solvent of low electroconductivity and a suspended dyestuff or pigment and/ or resin. From positive masters, positive images characterized by good contrast are produced.
- the fixed images may be transformed in printing plates: the support, e.g. the paper or plastic film, is wiped over with a solvent' for the photoconductive layer, e.g. alcohol or acetic acid. By this treatment, the non-image areas of the layer are removed, so that the support may now be rinsed with water. Subsequently, the support is inked in known manner with greasy ink which sticks to the imaged areas. In this way positive printing plates are obtained which can be set up in long runs.
- a solvent' for the photoconductive layer e.g. alcohol or acetic acid
- the electrophotographic images can also be used as masters for the production of further copies of any sort of light sensitive sheets.
- the photoconductive compounds to be used as provided by the invention are superior to the substances used hitherto, such as selenium or zinc oxide, inasmuch as the latter give cloudy layers which are not easy to be copied because solid solutions cannot be produced with such materials and only suspensions are possible.
- the paper After drying the coated layer, the paper is given a positive electric charge by means of a corona discharge. Thereafter a latent electrostatic image of a printed book page is produced on the paper by means of an episcopic process.
- the coated side of the paper is then treated with a developer consisting of very small glass balls melt-coated with a resin and of a very finely divided resin-carbon black mixture electrostatically adhering thereto.
- the black resin sticks to those areas of the layer which had not been exposed to light during exposure and a positive reproduction of the book page used as an original becomes visible.
- the copy is warmed gently and thus fixed. The image thus obtained shows good contrast.
- the coating is applied by means of an apparatus and has a thickness of about 6 microns.
- a corona discharge the paper thus coated is given a negative electrical charge and then placed with its coated side onto a book page printed on both sides and backed with black paper. Through the coated paper placed thereon, the book page is exposed for one second to the light of a watt incandescent lamp.
- the electrostatic reflex image thus produced on the paper is dusted with a developer powder consisting of 100 grams of glass balls (grain size 350 to 400 microns) and 2.5 grams of a toner powder (grain size 20 to 50 microns).
- the toner is prepared by melting together 30 grams of, polystyrol, 30 grams of a resin-modified maleic resin having a melting point at 95-105 C., a saponification number 20-25 (Beckacite K and 3 grams of a carbon 'black produced from natural gas by impingement process (Peerless Black Russ 552), whereupon the melt is ball-milled 'and sifted.
- a positive reverse image of the book page is obtained.
- By firmly pressing paper or a plastic film or a fabric onto the powder image obtained the image is transferred and anon-reversed image of the original becomes visible on the paper or the film or the fabric, respectively. As is.
- the transfer of the reverse powder-image can be favorably influenced by applying an electric field to the transfer paper or the film to carry the non-reversed image. If a transparent paper or film is used, intermediate originals are obtained from which further copies can be made, e.g. by means of a diazotype process.
- the carbon-black resin powder image is transferred from the electrophotographic layer onto the paper to form a reverse image on said paper. If the carbon-black-resin-image is thus transferred onto transparent paper or plastic film, the image obtained can be used for making further copies, e.g. on diazo printing paper.
- benzene The solution is coated onto an aluminum foil the surface of which has been made grease-free, and is then dried.
- an image of an original is produced on the coated foil and the image is developed by a powder-treatment and fixed by heating. Subsequently, it is transformed into a printing plate by wiping over the image side of the aluminum foil with 96% alcohol, rinsing With water and inking with greasy ink in the presence of 1% phosphoric acid.
- a positive printing plate is obtained which may be used for printing after clamping it into an offset printing machine.
