Abstract
Simulated photographic-quality prints are created using nonphotographic imaging such as xerography and ink jet. Reverse or wrong reading toner images are formed on a transparent subs,trate which is adhered to a coated backing sheet. The backing sheet is coated with a polymer material which serves as an adhesive and has a glass transition temperature less than 55.degree. C. A hydrophilic polymer coating having a melting point greater than 50.degree. C and a toner plasticizer having a melting point less than 75.degree. C contacting the adhesive polymer serves as a wetting agent for providing an enhanced optical interface as well as protection for the adhesive polymer which has a lower melting point than the adhesive polymer.
Claims20
A method of creating simulated photographic-quality prints, including the steps of:
- providing a coated transparent substrate having a toner image formed thereon by a xerographic or ink jet process;
- providing one surface of a backing member with a first coating comprising a polymeric adhesive binder having a glass transition temperature of less than 55.degree. C.;
- providing said one surface of said backing sheet with a second coating in contact with said first coating wherein said second coating comprises a hydrophilic polymer having a melting point of greater than 50.degree. C.;
- and a plasticizer having a melting point less than 75.degree. C.;
- and
- adhering said substrate to said one surface of said backing sheet at a temperature of about 100.degree. C. to about 150.degree. C. and a pressure of about 75 psi to about 125 psi.
