Abstract
A master adapted to be imaged in the manner of an electronic stencil for use in producing multiple copies containing latent images in which the master comprises a base sheet having multiple coatings including a first coating containing an alcohol and/or water soluble colorless colorforming component and a highly electrically conductive coating overlying the first coat and which, in addition, contains a less highly electrically conductive coating overlying the highly electrically conductive coating and a masking coat as the top coat.
Claims12
A master for producing multiple latent imaged copies comprising a base sheet and multiple coatings on the surface of the base sheet including a base coat containing a water and/or alcohol soluble colorless color-forming component and at least two electrically conductive coatings overlying the base coat containing electrically conductive particles arranged to provide an electrical gradient of increasing conductivity in the direction towards the base coat.
