    摘要: A method is disclosed for the manufacture of a ceramic material for fillings or dental prostheses, which includes the steps of forming a precipitation product having at least one slightly soluble calcium phosphate compound, which has at least two phases of crystals; the slightly soluble calcium phosphate compound being a replacement for dental tissue. The precipitation product further includes a freely soluble compound dissolvable in the saliva of a patient's mouth and which creates a porous structure within the slightly soluble phase. The pores of this structure are filled by precipitating ions from the patient's saliva. The precipitation product is then sintered and dried, before being explosively compressed to form the ceramic dental filing material.

    摘要: An electrophotographic recording material is described that comprises an electrically conducting base layer and a photoconductive system deposited thereon, which system comprises an optional insulating intermediate layer, a layer containing a charge-generating compound, and a layer containing a charge-transporting compound mixed with binders, along with any sensitizers, acceptors and usual additives. The photoconductive system contains, as acceptor additive, one or more monomeric or polymeric compounds that have electron-attracting substitutents (halogen, cyano, nitro groups) and that are selected from the group consisting of anthracene, acridine, the anhydrides of phthalic acid, maleic acid, pyromellitic acid, benzophenonetetracarboxylic acid, and the polymers of vinyl chloride, vinylidine chloride and nitrocellulose, in a quantity of 0.2 to 10% by weight based on total coating weight. After erasure of the latent electrostatic image, the recording material has a low residual charge, even when operated cyclically. Background imaging is thereby avoided.

    摘要: An electrophotographic recording material comprising an electrically conductive base material, an option insulating intermediate layer, and a photoconductive double layer comprised of a charge-generating and a charge-transporting layer employs a pyrimido[5' ,4':5,6]-pyrido-[1,2-a]-benzimidazole transport compound, along with a binder and a dye or pigment, in the charge transporting layer, which compound is represented by the formula I ##STR1## wherein R.sub.1 and R.sub.2 are identical or different and denote hydrogen or an R.sub.3 R.sub.4 N group; R.sub.3 and R.sub.4 are identical or different and denote (C.sub.1 to C.sub.4)-alkyl, hydroxy-(C.sub.1 to C.sub.4)-alkyl, optionally (C.sub.1 to C.sub.4)-alkyl-substituted phenyl or benzyl, or, together with the nitrogen atoms to which they are bonded, an imidazolyl or a triazolyl group; and R.sub.5 denotes a benzothiazole, a benzoxazole, a benzimidazole or a cyano group. Use of the transport compound makes it possible to adjust the photosensitivity of the recording material to different spectral regions when the material is subjected to electrostatic charging of different polarities.
