  • Patent number: 5795695
    Abstract: Disclosed is a method of creating simulated, photographic-quality prints using transparent polyester substrates such as Mylar.RTM.; polypropylene, and the like. Reverse or wrong reading images are formed on the substrate using a linear or crosslinked low melt polyester toner and mixtures thereof. The reverse or wrong reading images are permanently adhered to the polyester substrate followed by the application of a backing member to the imaged transparent substrate. The backing member is characterized by being opaque and being coated with linear or crosslinked low melt polyester resin system to generate high fidelity, grain free photographic-quality images with reduced curl and improved adhesion due to similar rheological responses of the compatible materials in the toner, imaging substrate and the backing substrate.
