摘要： An inverse dual-layer organic photoconductor comprising a charge generation layer (CGL) formed on top of a charge transport layer (CTL), in turn formed on a substrate such as a web (drum) or subbing layer, is disclosed, in which the CGL includes a flexible polymer having a glass transition temperature (T.sub.g) of less than about 120.degree. C. as the binder for a charge generation species and in which the CTL includes a rigid polymer having a T.sub.g of greater than about 120.degree. C. as the binder for a charge transport species. The CTL is coated onto the substrate, using a non-chlorinated solvent. The CGL is coated onto the CTL, also using a non-chlorinated solvent, under conditions so as to form a diffused region at the boundary of the CGL and CTL. This type of photoconductor yields extremely low noise, exceptionally high-speed and excellent stable charging/discharging performance in the xerography process at room temperature and elevated temperature.

摘要： Composites comprising polymeric binders and phthalocyanine pigments to form a single layer positive organic photoconductor are provided for use in electrophotography. The polymeric binders comprise an aliphatic polymer or copolymer having a saturated ring for each repeat unit either included in the polymer chain or pendant therefrom and about 4 to 35% of functional groups such as --OH, --SH, --N NH, and --NH.sub.2 per repeat unit. The saturated ring portion, being essentially non-polar, or at least less polar than an unsaturated ring, maintains the specific morphology of the phthalo-cyanine pigments commonly employed in positive charge organic photoconductors (OPCs) and results in a stable dispersion required for the stable performance of the OPC. Keeping the functional groups listed above to less than about 35% ensures that the photoresponse is not reduced to an unacceptable level. Heating of the composite is used to control the concentration of the functional groups. One or more separate thermal carrier generation control agents comprising compounds containing the functional group(s) may be used to provide part or all of the functional groups in the composite. The resulting composite evidences thermal stability of electronic properties, such as dark decay, at elevated temperatures in the range of about 35.degree. to 75.degree. C.

摘要： Water-fastness in aqueous ink-jet inks containing water-soluble dyes is achieved by using a specific ionic species having a charge opposite to that on the dye molecule. Anionic dyes typically contain sulfonate (or carboxylate) anionic groups. Using at least one specific ionic species of opposite charge, specifically, phosphonium salts, causes the colorant components to “crash” or precipitate out of the water-based ink onto the print medium due to the formation of a suitable charge complex between the ionic parts of the dye and the opposite charge of the counter-ion species. Other positively charged salts, such as quaternary ammonium salts, carbonium salts, iodonium salts, sulfonium salts, and pyrillium salts may be used to improve aqueous dispersion stability and thus printability. Such additional cationic salt partially replaces the phosphonium salt(s). Alternatively, certain surfactants, such as aromatic ethoxylates, polyethylene oxide ethers, or polypropylene oxide ethers may be used to improve print quality.

摘要： Lightfast additives for inkjet inks are provided. These additives exhibit excellent lightfastness of many dyestuffs (both water-soluble and water-insoluble).

The lightfast additive comprises a molecule which is composed of three parts or moieties: A—X—B, where (a) moiety A is an aryl sulfonic acid or aryl carboxylic acid, either in acid form or salt form, with or without substituents (e.g., benzene sulfonic acid, naphthalene mono-sulfonic acid, naphthalene di-sulfonic acid, benzoic acid, benzene sulfonic acid sodium salt, and hydroxybenzenesulfonic acid sodium salt), that contributes to the water solubility and compatibility (molecular overlapping) with the dye molecule in the solid state; (b) moiety B is a triazine, benzotriazole, tetrazole, or benzimidazole, with or without substituents, that contributes to improvement of lightfastness of the dye; and (c) moiety X is a connector (—NR— or —O—) between A and B.
