Abstract: A method for producing a light-transmissive printed substrate is provided. The substrate is printed with a predetermined pattern of a light-transmissive phase change ink which initially transmits light in a non-rectilinear path. When the pattern of solidified phase change ink is subsequently reoriented to form an ink layer of substantially uniform thickness, a printed image layer is formed which will transmit light in a substantially rectilinear path and is suitable for overhead projection.In some instances the adhesion between the ink image layer and the substrate is not as high as is desired. This problem can result in delamination of the ink from the film under certain conditions. In order to overcome this problem, an intermediate optically clear adhesion promoting layer is introduced between the light-transmissive phase change ink and the base substrate.
