    摘要: Disclosed is a liquid developer composition comprising a liquid vehicle, a charge control additive, and toner particles containing pigment particles and a resin selected from the group consisting of polyolefins, halogenated polyolefins, and mixtures thereof. Preferred resins include poly-.alpha.-olefins and chlorinated polypropylenes. The resin is soluble in the liquid vehicle at elevated temperatures and insoluble in the liquid vehicle at ambient temperatures. Also disclosed is a liquid developer composition comprising a liquid vehicle, pigment particles, a charge control additive, and a resin selected from the group consisting of polyolefins, halogenated polyolefins, and mixtures thereof, wherein the resin is soluble in the liquid vehicle at elevated temperatures and insoluble in the liquid vehicle at ambient temperatures, and wherein the liquid developer is prepared by dissolving the resin in the liquid vehicle at temperatures of from about 80.degree. C. to about 120.degree. C., subsequently adding the pigment particles to the resulting solution, attriting the resulting mixture for from about 20 minutes to about 75 minutes, cooling the mixture to ambient temperature over a period of from about 1 hour to about 3 hours with continuous mixing, and subsequently adding to the mixture the charge control additive.

    摘要: Disclosed is a process for forming secure images which comprises electrostatically charging an imaging member; imagewise exposing the charged member, thereby forming a latent image on the member; developing the latent image with a liquid developer comprising a liquid medium, a charge control additive, and toner particles comprising a colorant and a polymeric material; allowing the developed image to dry on the imaging member; contacting the portion of the imaging member with the dry developed image with a substantially transparent sheet having an adhesive material on the surface thereof in contact with the imaging member, thereby transferring the developed image from the imaging member to the substantially transparent sheet; contacting the adhesive surface of the substantially transparent sheet with the developed image with a paper sheet having a polymeric coating on the surface that is in contact with the substantially transparent sheet; and applying heat and pressure to the substantially transparent sheet and the paper sheet at a temperature and pressure sufficient to affix the image permanently to the paper. The resulting document is a paper sheet covered with the transparent sheet, with the developer material that forms the image being situated between the paper sheet and the transparent sheet. The disclosed process is generally useful for applications such as passport photographs, identification badges, banknote paper, and the like.
