An image receptor medium is disclosed as having a base medium, a hot melt layer adjacent to the base medium, and a porous imaging layer. An image may be imparted to the imaging layer, and heat and pressure may then be applied to the image receptor medium. A substantial number of the pores in the porous imaging layer are filled by the material of the hot melt layer, thereby fixing the image. The image receptor medium can be backed with an adhesive/release liner combination or mechanical fasteners to provide securing means or can be left without such means for &ldquo;drop-in&rdquo; backlit or other nonadhesive uses.

Image receptor medium with hot melt layer, method of making and using same

An image receptor medium is disclosed as having a non-porous base medium and an imaging layer. The imaging layer includes a solvent-soluble multivalent cationic salt coated from an organic solvent. A water-insoluble binder holds the imaging layer together. The imaging layer also includes organic-solvent insoluble particulates. The image receptor medium can be backed with an adhesive/release liner combination or mechanical fasteners to provide securing means or can be left without such means for &ldquo;drop-in&rdquo; backlit uses.
