    • Electrically biasable transfer members for use in electrostatographic transfer processes for transferring toner images from one support surface to another and to methods for their preparation are described. The electrically conductive biasable transfer members comprise a conductive substrate capable of supporting a uniform bias potential thereon and at least one coating comprising a resilient crosslinked elastomeric polyurethane formed by reacting (a) a polyisocyanate prepolymer comprising the reaction product of an aliphatic polyisocyanate and a polyether polyol selected from the group consisting of a polyalkylene glycol having 2 to 3 carbon atoms in the alkylene group, and (b) a hardening mixture comprising a polyether polyol of (a) and, as a conductivity control agent, from .01 to 3.0 weight percent based on the total weight of (b) of a complex of an oligoethylene glycol selected from the group consisting of di-, tri- and tetraethylene glycol with an ionizable alkali metal salt selected from the group consisting of sodium iodide, lithium iodide and sodium thiocyanate.
      The resistivity of the elastomeric resilient polyurethane coating on the biasable member is controlled or adjusted to within a desired level of resistivity due to the inclusion of the conductivity control agent in the crosslinked polyurethane elastomer. Additionally, the inclusion of the conductivity control agent in the crosslinked polyurethane elastomer reduces the sensitivity of the resistivity of the polyurethane coating on the biasable member to changes in relative humidity. Further, since the conductivity control agent is copolymerized with the polyisocyanate prepolymers and polyols used to make the elastomeric polyurethane coatings of the biasable members of the invention, the conductivity control agent is bonded covalently to the backbone and/or the crosslinking portion of the polyurethane elastomer where it forms a permanently fixed part of the crosslinked polymer and will not migrate therefrom resulting in a continuous change in the resistivity of the polyurethane coating over time and possible adverse affects on materials that may come into contact with the migrating agent. The utility of such biasable members is in the transfer of toner images from a photoconductor to a final support sheet where the member, for example, a bias transfer roll, electrically cooperates with a photoconductor to establish a directional force field therebetween.

    • PURPOSE:To dispense with devices for coating, drying, exposing, developing, etc., by laminating a scribable layer low in resistivity and a dielectric scribable layer on a transparent film support. CONSTITUTION:The low resistivity scribable layer is formed on the transparent film support by using a coating fluid prepared by mixing an electrically conductive resin, a dye, a pigment, a filler, etc., with an alkyd resin or the like, and dissolving or dispersing them in an org. solvent. Then, the dielectric scribable layer is formed on this layer by using a coating fluid prepared by dissolving or dispersing a mixture of a styrene-modified alkyd resin, an alkyd resin, a filler, a pigment, etc., in an org. solvent. Since this scribable electrostatic recording film uses no photosensitive material, a coating device, a drying device, an exposing device, a developing device, etc., are not necessary.
