摘要:
A multi-active photoconductive insulating element having at least two layers comprising a charge-generation layer and an organic photoconductor-containing charge-transport layer is disclosed. The charge-generation layer contains a continuous polymeric phase having dispersed therein a co-crystalline complex composed of (i) at least one polymer having an alkylidene diarylene group in a recurring unit and (ii) at least one pyrylium-type dye salt.
摘要:
A method of forming a toner image on a receiving sheet includes a step of either transferring or fixing a toner image to the receiving sheet, in which the receiving sheet is heated to a temperature of at least 100.degree. C. To allow steam to escape from the receiving sheet, a gas impermeable layer on the side of the sheet opposite the toner image is made permeable by application of small, closely spaced holes in the layer. The method is particularly usable with a receiving sheet having a heat-softenable layer which is heated beyond its softening point to facilitate transfer of images made up of very small toner particles. The holes are preferably mechanically punched in a curl-preventing layer on the opposite side of the sheet.

Transparent image-recording elements that contain ink-receptive layers that can be imaged by the application of liquid ink dots. The ink-receptive layers contain a combination of:(i) a vinyl pyrrolidone;(ii) particles of a polyester, namely a poly(cyclohexylenedimethylene isophthalate-co-sodiosulfobenzenedicarboxylate);(iii) a homopolymer or a copolymer of an alkylene oxide containing from 2 to 6 carbon atoms;(iv) a polyvinyl alcohol;(v) nonylphenoxypolyglycidol; and(vi) inert particles.A printing method which employs the transparent image-recording elements also is described.
摘要:
Photoconductive and radioconductive insulating compositions of desirably low dark conductivity and improved resistance to fatigue include tetragonal lead oxide, a binder of polyvinylacetate, polyvinylformal and/or polyvinylbutyral and a small effective amount of an anhydride capable of inhibiting dark conductivity in the composition, particularly under repeated use. Preferred anhydrides are phthalic and maleic anhydrides in an amount of less than about 4 percent of the weight of lead oxide in the composition. Such compositions can be carried on an electrically conductive support to provide elements that are useful for electrophotographic and electroradiographic imaging.

摘要:
Transparent image-recording elements that contain ink-receptive layers that can be imaged by the application of liquid ink dots. The ink-receptive layers contain a combination of a vinyl pyrrolidone polymer with a polyester, a poly(cyclohexylenedimethylene-co-xylylene terephthalate-co-malonate-co-sodioiminobis(sulfonylbenzoate)) dispersed in the vinyl pyrrolidone to control ink dot size. A printing method which employs the transparent image-recording elements is described.

摘要:
A process is provided for providing a non-electrostatically transferred toned image. From the surface of an element, the image is thermally transferred by contact to the face of a thermoplastic film that is strippably laminated to a paper or like backing. The film is then positioned against a receiver with the toner image therebetween, and the resulting composite is subjected to two successive stages of compressive heating. The process is particularly well suited for producing high resolution images from very small particle size toner powder on rough paper.
