Abstract
A composite panel material for the back-lit display of graphic and alphanumeric designs and color fields as disclosed which includes regions that appear metallic and highly reflective when front-lit but which when back-lit transmit a portion of the back-lighting to give a "see-through metal" effect. Panelling material according to the design comprises a transparent base medium, daytime design images which are visible when the panel material is front- but not back-lit, and a partially reflective metallized element which appears opaque and shiny when front- but not when back-lit, of a pre-selected degree of transparency to permit the viewing of one set of images and colors in front-lighting and a different set under back-lighting of the panel material.
