PROBLEM TO BE SOLVED: To provide a nonflammable film material for an illumination cover (including inside-lit signboard) and a luminous ceiling, using glass woven fabric as a base material, which has a high illumination effect and shades a light source and, especially, when the film material is held over the light source, alleviates defects of shadows by thread line of fabric and textile construction, and shadow contrast due to partial loosening and slippage of textile construction, and produces beautiful luminescent appearance.SOLUTION: The nonflammable film material for the illumination cover has glass woven fabric as a base material and is provided with a light-transmitting resin-coated layer on one side of the base material, and is further provided with a light diffusion resin-coated layer which includes specific crushed glass powder being infinite-form and irregular reflection particles, on the other side of the base material, in a specific amount. |
