ABSTRACT:
Simulated photographic-quality prints are created using non-photographic imaging such as xerography and ink jet. Reverse or wrong reading toner images are formed on a transparent substrate which is adhered to a coated backing substrate. The backing substrate is coated with a two layered adhesive composition where the first layer in contact with the substrate of the backing substrate is a polymeric material which serves as an adhesive and has a glass transition temperature of less than 55.degree. C. The second layer on the top of the adhesive layer is a blend of a hydrophilic polymer having a melting point greater than 50.degree. C. and a fluoro compound containing from 1 to about 25 fluorine atoms. The desired melting point of the fluoro compound is less than 100.degree. C. and preferably between about 50.degree. to about 100.degree. C. The fluoro compound in combination with the hydrophilic polymer serves as a toner wetting agent for providing an enhanced optical interface. It also protects the adhesive polymer which has a lower melting point than the hydrophilic polymer as well as the fluoro compound from premature activation.
