Abstract
Disclosed is a carbonless paper set having at least two sheets, wherein a first sheet comprises paper coated on one surface with a color former and a second sheet comprises paper coated on one surface with a color developer, and wherein at least one of the sheets contains an oleophilic pigment filler material on the surface of the sheet opposite to that coated with the color former or color developer. Also disclosed is a process for generating images which comprises generating an electrostatic latent image on an imaging member in an imaging apparatus, developing the latent image with toner particles of one polarity, contacting the developed image on the imaging member with the first sheet of the carbonless paper set disclosed herein, applying an electric charge of a polarity opposite to that of the toner particles to the surface of the first sheet opposite the surface in contact with the imaging member, thereby transferring the developed image to the first sheet, generating an electrostatic latent image on the imaging member in the imaging apparatus, developing the latent image with toner particles of one polarity, contacting the developed image on the imaging member with the second sheet of the carbonless paper set disclosed herein, applying an electric charge of a polarity opposite to that of the toner particles to the surface of the second sheet opposite the surface in contact with the imaging member, thereby transferring the developed image to the second sheet, and optionally permanently affixing the transferred images to the first and second sheets.
