Abstract: An organosol comprising a high molecular weight (co)polymeric steric stabilizer covalently bonded to an insoluble, high molecular weight thermoplastic (co)polymeric core is described which has the ability to form a three dimensional gel of controlled rigidity. The gel provides improved liquid ink or liquid electrophotographic/electrographic toner compositions by increasing sedimentation stability of the colorant, without compromising print quality or ink transfer performance. The gel is formed by manipulating the solubility parameter difference between the stabilizer and the solvent to achieve optimum performance of the dispersion.

Abstract: A liquid ink composition containing organosols having side-chain or main-chain crystallizable polymeric moieties is described. The incorporation of organosols having crystallizable polymeric moieties into the ink compositions provide improved blocking resistance and improved erasure resistance when used in ink transfer, ionographic, electrographic and electrophotographic color printing or proofing processes.

Abstract: A method of transferring a high resolution polarizing image from a mass transfer donor element to a receptor element. The transfer can be induced by thermal energy or electromagnetic (optical) energy. In either case, the transferred image will be a high resolution image that exhibits optically anisotropic properties. The polarizing mass transfer donor element comprises a substrate having a polarizing mass transfer layer coated thereon. Optionally, the polarizing mass transfer donor element further comprises a light absorbing material, preferably in the form of a light to heat conversion layer. The polarizing mass transfer donor element can further comprise an adhesive to facilitate transfer of the polarizing mass transfer layer.

Abstract: Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0.5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor.

Abstract: Retroreflective appliques comprising a monolayer of retroreflective elements partially embedded in and protruding from the front surface of a binder layer and an optional layer of adhesive on the rear surface of the binder layer, wherein the binder layer, the adhesive layer, or both contain a metal-azo dye to camouflage the color of any exposed portions of said binder layer. Appliques comprising micropheres with aluminum reflectors as retroreflective elements and a black metal-azo dye in the binder layer will exhibit a pleasing silver appearance even after portions of the binder layer have been visibly exposed due to degradation of the aluminum reflectors, typically as a result of subjecting the applique to harsh laundering conditions.

Abstract: An electrographic imaging process is described in which electrostatic images are toned in sequence to form a multicolor intermediate image on a temporary dielectric receptor. The intermediate image is then transferred to a permanent receptor. Certain relative properties of the toner and the intermediate image, such as surface energy, T.sub.g, work of adhesion, and complex dynamic viscosity, have been found to be important to the production of good final images.

Abstract: A novel donor construction is used for thermal mass transfer imaging applications. The donor constructions are coated from pigment dispersions which are flushed in solutions containing a chlorinated wax. Because of near refractive index matching to the coloring pigments and the low cohesive strength of the chlorinated wax, this novel thermal mass transfer system is characterized by low transfer energy requirements and high transparency in the transferred images.
