A laminate comprises a core layer and a surface layer on at least one face of the core layer. An optical brightener has been incorporated in the surface layer to enhance the brightness of the surface of the decorative layer. An independent claim is also included for a method of preparing a printable laminated panel used as a display in the graphic arts industry, comprising preparing a resin formulation comprising a resin, an optical brightener, and optionally, a dye; impregnating at least one cellulosic sheet with the resin formulation; applying the cellulosic sheet to at least one face of a plastic core substrate; and forming a display panel having an enhanced surface brightness.
